The last decade has seen an explosion of domestic climate change litigation around the world and an equally rich body of academic literature examining the case law from a variety of disciplinary perspectives. The Sabin Center for Climate Change Law maintains an excellent data base[1] covering these developments. Important cases in other jurisdictions include the Urgenda decision[2] and Shell[3] decision in the Netherlands, and the 2021 decision of the German constitutional court[4]. Australian environmental non-governmental organizations (ENGOs) have been particularly active in bringing climate change issues before the courts, especially in the context of proposed natural gas and coal projects, most famously in the Sharma case[5].
These cases have different doctrinal and theoretical bases. Some are based on domestic constitutional law; some on the domestic implementation of international human rights treaties; and some, like Sharma, on principles of tort law. And while ENGOs have been met with significant successes, there have also been significant setbacks — perhaps most surprisingly in Norway.[6]
Within this broader global context, climate change litigation in Canada, especially rights-based litigation, has been slow to emerge, but with the La Rose[7] decision of the Federal Court of Appeal (the subject of this article) and the Mathur[8] case in the Ontario courts, we are starting to see some engagement. In Mathur v Ontario,[9] and Mathur v His Majesty the King in Right of Ontario,[10] the applicants challenged Ontario’s greenhouse gas emissions reduction target as contrary to section 7 (the right to security of the person) and section 15 (the right to equality) of the Canadian Charter of Rights and Freedoms.[11] The application was permitted to proceed to a hearing on the merits after surviving the Ontario government’s motion to strike, but was unsuccessful at trial. Justice Marie-Andrée Vermette of the Ontario Superior Court of Justice ultimately concluded that there was no violation of section 7 since the “[a]pplicants have not demonstrated that any deprivation of their rights under section 7 of the Charter was contrary [to] the principles of fundamental justice…”[12] Neither was there a breach of section 15, principally because any disproportionate impact that would be experienced by the applicants as youth would be caused by climate change itself and not by Ontario’s greenhouse gas reduction target.[13] The applicants’ appeal was heard by the Ontario Court of Appeal in January 2024 and judgment was reserved.
The La Rose plaintiffs are 15 children and youth residing in seven provinces and one territory. In this case, the target is the federal government. The plaintiffs allege that the government’s failure to address the problem of climate change constitutes a breach of sections 7 and 15 of the Charter. The La Rose plaintiffs also allege that Canada is in breach of its public trust duties, in particular its duty “to preserve and protect inherently public resources — bodies of water, the air, and the permafrost — so that current and future generations may access, use, and enjoy these resources.”[14] The plaintiffs’ requests for relief — discussed in the Federal Court decision considering the government’s motion to strike — included “an order requiring the Defendants to develop and implement an enforceable climate recovery plan that is consistent with Canada’s fair share of the global carbon budget plan to achieve GHG emissions reductions compatible with the maintenance of a Stable Climate System”.[15] The plaintiffs referred to a Stable Climate System as a climate “capable of sustaining human life and liberties.”[16] Justice Michael Manson of the Federal Court granted Canada’s motion to strike principally on the basis that the claims were not justiciable. On appeal, in a unanimous judgment written by Justice Donald Rennie, the Federal Court of Appeal affirmed the motion to strike in relation to the section 15 claim but allowed the appeal in respect of the plaintiffs’ section 7 claim — at least to the extent that the Court gave the parties leave to amend their pleadings.[17]
Justice Rennie’s judgment also provides the Court’s reasons for the appeal in the companion case of Misdzi Yikh v Canada.[18] This was a case brought by two Wet’suwet’en House groups represented by their Dini Ze’ (Head Chiefs) alleging that the federal government’s actions in relation to climate change amounted to a breach of sections 7 and 15 of the Charter and a failure by Canada to make laws in relation to peace, order and good government. Justice Glennys McVeigh of the Federal Court had struck the Misdzi Yikh claim in its entirety.[19]
Justice Rennie found that the section 7 Charter claim could proceed with amended pleadings here too.
This article begins with, and focuses on, Justice Rennie’s reasons for decision in the La Rose case but we also offer some comments on the Misdzi Yikh case.
THE TEST FOR A MOTION TO STRIKE
A claim should be struck if it is plain and obvious that the claim has no reasonable prospect of success. In applying this standard, “the facts are to be taken as proven unless they are manifestly incapable of proof…the pleading must be read generously and, recognizing that the law is not static and evolves to address new and emerging situations, the court must err on the side of permitting novel but arguable claims to proceed to trial…”[20]
JUSTICIABILITY
Justice Rennie noted several possible bases for striking the claims: non-justiciability, failure to disclose a reasonable cause of action, or a failure of the pleadings.[21] A claim is justiciable if a court has both the institutional capacity (what a court can do) and legitimacy to adjudicate the matter (what a court ought to do). A question is justiciable in a constitutional case if it concerns the validity of government (in)actions rather than the wisdom of the choices made by Parliament. Questions as to the wisdom of actions or inactions are issues to be determined by the legislative or executive branches of government within a Westminster parliamentary system rather than the judicial branch.[22] A claim is not rendered non-justiciable just because it concerns matters that are politically sensitive or controversial so long as the claim has a sufficient legal component.[23]
In applying these tests in the La Rose case, Justice Rennie concluded that the plaintiffs’ claims were justiciable. He noted that the question of climate change was not simply a matter of political choice since it had been crystallized into law. Here, Justice Rennie referenced[24] the preamble of the Greenhouse Gas Pollution Pricing Act,[25] which in turn references Canada’s commitment to achieve its Nationally Determined Contribution under the Paris Agreement.[26] Furthermore, “[i]t must not be forgotten that the target of the appellants’ claims is legislation — existing laws, regulatory instruments and Orders in Council.”[27] It followed that there is, “therefore, a sufficient legal component to their claims, and the claims satisfy the legitimacy portion of a justiciability analysis.”[28]
In reaching this conclusion, Justice Rennie was able to distinguish the decision in Friends of the Earth v Canada (Governor in Council).[29] As Justice Rennie noted,[30] Friends of the Earth was a case in which the conclusion as to non-justiciability largely turned on the determination that Parliament allocated the accountability mechanisms in the Kyoto Protocol Implementation Act,[31] to Parliament itself and not to the courts. We agree with this assessment and also agree that Friends of the Earth cannot “stand for the proposition that all claims addressing climate change are inherently non-justiciable.”[32]
While this analysis revealed a sufficient legal target, it was also necessary to assess whether that target was too diffuse and whether a court had the institutional competence to tailor “effective, enforceable remedies to meaningfully address the asserted harms.”[33] Here, Justice Rennie cautioned that a court should be slow to conclude that the remedies sought might render a claim non-justiciable. After all, the courts have the capacity to issue a suspended declaration as a response to unconstitutional behaviour so as to afford the legislative branch the opportunity to respond.[34] In addition, climate change science has been evolving so as to allow “a science-based GHG reduction target,” meaning that “a stable climate system could be established through expert evidence” at trial.[35] This is an important acknowledgement of the concept of a Stable Climate System even though Justice Rennie does not expressly refer to the idea of a carbon budget. Justice Rennie went on to note that requests for remedies are often amended in the course of litigation and while some of the plaintiffs’ requests for remedies might be overly prescriptive or overly general, there would still be the opportunity to tailor remedies appropriately should a breach be found.[36]
In sum, the claims in La Rose were found to be justiciable and the same conclusion must presumably apply to the claims in Misdzi Yikh. This is a significant conclusion, fully in line with the case law in other jurisdictions and with Mathur. In our view, it would be a very strange and unfortunate outcome if rights-based climate change cases were justiciable in other jurisdictions but not here in Canada.
PLAIN AND OBVIOUS AND THE SUBSTANTIVE LAW
With the threshold issue of justiciability disposed of, Justice Rennie could turn to the substantive law underlying the specific claims of the plaintiffs to see if they would falter under the plain and obvious test for failing to disclose a reasonable cause of action. First up was the non-Charter public trust argument of the youth plaintiffs.
THE PUBLIC TRUST CLAIM
The public trust doctrine does not have the salience in Canadian law generally, or in Canadian constitutional law specifically, that it does in the United States. For this reason alone, it is hardly surprising that Justice Rennie declined to interfere with Justice Manson’s conclusion that the plaintiffs’ claim did not disclose a reasonable cause of action.[37] Justice Rennie found that the government’s standing (or power) to act in the public interest did not translate into a general obligation for it to do so.[38] This does not mean that all public trust claims are doomed to failure, but any effort to apply such a doctrine across the whole of the federal government was a leap too far. Better to build this doctrine incrementally — the methodology of the common law — rather than proclaiming a brave new world.
THE POGG CLAIM OF THE MISDZI YIKH PLAINTIFFS
The next issue Justice Rennie addressed was the claim of the Misdzi Yikh plaintiffs in relation to the federal government’s peace, order and good government (POGG) power. Similar to the public trust doctrine, the plaintiffs faced the challenge of converting a federal power to make certain types of laws into a duty to make a law co-extensive with the power (and a correlative right of the plaintiffs to see that such a law would be enacted). That is no small undertaking, and much like our comments above with respect to the public trust doctrine, this is not the case in which to try to use POGG to convert a legislative power into a justiciable duty to act. If there is such a duty, it must arise from the rights-conferring terms of the Charter, not from the language of the power to make laws, or from principles of federalism. In other words, POGG does not supply a free-standing cause of action, but if the plaintiffs can establish a Charter basis for protective measures, then it does seem possible that a court might be able to order federal action, even if that requires the federal government to rely on its POGG power. After all, insofar as it is provincial inability that feeds the POGG power,[39] the federal government might be the only government with the power to take the necessary protective action. But in this case, the Misdzi Yikh plaintiffs do not seem to have expressly combined their POGG and Charter arguments.
Hence, we agree with Justice Rennie’s conclusions striking the POGG claim,[40] but we do caution that his comments with respect to reliance on comparative and international jurisprudence need to be interpreted in context, as we elaborate in the next paragraph.
The Misdzi Yikh plaintiffs based their case on the Bancoult or Chagos Islands decisions of the UK courts,[41] which considered whether the British government’s POGG powers extended to the executive’s politically motivated removal of the inhabitants of the British Indian Ocean Territory. Justice Rennie dismissed any reliance on these cases in terms of the merits of the arguments but also more broadly reasoned as follows:
In any event, constitutional analysis is principally informed by Canadian jurisprudence, which is in turn shaped by our political and social history and only draws upon decisions of foreign courts or principles of international or comparative law in exceptional circumstances (Quebec (Attorney General) v. 9147-0732 Québec inc., 2020 SCC 32, [2020] 3 S.C.R. 426 at paras. 43–47). This practice is driven by the obvious reality that measures adopted in other contexts may be of scant relevance, a point particularly apposite in respect of the Bancoult decisions.[42]
While we generally agree with this sentiment when it comes to questions of division of powers, and specifically the interpretation of POGG in the context of principles of Canadian federalism, we fundamentally disagree with this sentiment as applied to rights-based litigation (and the Charter) in the context of climate change litigation. Insofar as much of this litigation is rooted in an internationally shared set of human rights norms, we think that both international and comparative jurisprudence (as outlined in our introductory paragraphs) should be of considerable interest and value to Canadian courts. We note that both the Supreme Court of Canada in the GGPPA Reference,[43] and Justice Vermette in the Mathur case[44] seem to be much more open to engaging with this jurisprudence.
There is also one more specific reason for engaging with international law in the context of Indigenous plaintiffs and climate law, and that is because of the jurisprudence of the UN Human Rights Committee on article 27 (the minority rights provision) of the International Covenant on Civil and Political Rights.[45] This jurisprudence is important because of the Committee’s insistence that article 27 (even though framed negatively) may in some circumstances require a state party to take positive measures to ensure that Indigenous minorities continue to have access to the material elements of their culture.[46] Given the judicial reluctance to interpret Charter rights as imposing a government duty to take positive protective measure to ensure the enjoyment of the right (see the discussion below), this jurisprudence supports a more generous reading of rights as more than just protections against the state.
CHARTER CLAIMS
This brings us to the plaintiffs’ Charter claims. Justice Rennie began with the equality guarantee in section 15 and the youth plaintiffs’ argument that climate change affects them disproportionately, with the lack of a robust legislative response amounting to adverse effects discrimination based on age. As noted by the Court, a violation of section 15 is assessed via a two-step test: (1) “whether the law or state action creates a distinction [or has a disproportionate impact] based on an enumerated or analogous ground,”[47] and (2) “whether the law or state action imposes burdens or denies a benefit in a manner that perpetuates, reinforces, or exacerbates some disadvantage experienced by the group, either systemically or historically.”[48]
At the outset of his analysis, Justice Rennie recognized that “[c]limate change is having a dramatic, rapidly unfolding effect on all Canadians and on northern and Indigenous communities in particular”[49] and that it is “beyond doubt that the burden of addressing the consequences will disproportionately affect Canadian youth.”[50] While accepting the principle that where the government has conferred a benefit or imposed a burden, it must do so without discrimination, Justice Rennie also noted that governments are “free to address inequality incrementally”[51] and do not have a “freestanding positive obligation…to enact benefit schemes to redress social inequalities.”[52] He characterized the plaintiffs’ claim as one related to future inequalities and intergenerational inequity, and found that it was not the proper role of the courts to address such harms.[53] Justice Rennie noted that age discrimination claims are unique in that age is experienced universally and it is accepted that government actions “will, of necessity, affect different generations differently.”[54] Although the international community is beginning to recognize youth climate rights and intergenerational equity, obligations such as those flowing from the Convention on the Rights of the Child[55] did not factor into the section 15 framework in a manner that would support the plaintiffs’ argument.[56] Justice Rennie upheld the decision to strike the plaintiffs’ section 15 claims without any leave to amend.
This left the section 7 claims, which were to be assessed on the basis of: (1) whether the law or state action deprived the plaintiffs of their life, liberty or security of the person, and (2) whether this deprivation was contrary to the principles of fundamental justice.[57] Justice Rennie also noted the need for the pleadings to draw a sufficient causal connection between the impugned state action and the prejudice suffered by the plaintiffs.[58]
Justice Rennie’s analysis of positive versus negative rights, focused on the idea that section 7 protects against the deprivation of life, liberty, and security of the person by the state, rather than providing a right to a legislative regime or state action that furthers these interests.[59] That said, he acknowledged that the Supreme Court and lower courts have left the door open on the argument that section 7 might encompass positive rights claims in special circumstances, an approach that is particularly important for recognizing Canada’s international human rights obligations.[60] Justice Rennie also noted that it is well accepted that the dividing line between positive and negative rights can be difficult to draw[61] and that the positive/negative orientation of a right might simply depend on the perspective taken.[62] He used an excellent example to illustrate this point, referring to the right to accessibility for persons with disabilities who require assistive devices, “but only because the state has constructed inaccessible programs and infrastructure.”[63]
In the environmental law context, it is useful to recall that, prior to the expansion of the modern environmental state, the common law’s position was that “[p]ollution is always unlawful and, in itself, constitutes a nuisance.”[64] Subsequently, modern environmental laws were passed to broadly prohibit environmental harms in one breath, but also to open the door to regulatory (i.e., statutory) authorization of such harms in the next. In other words, like the disability example where Justice Rennie noted the state’s construction of inaccessible programs and infrastructure, so too has the state authorized climate-destabilizing industries and activity that now threaten the plainitffs’ Charter rights.
Justice Rennie also found that the requirement that the state expend funds to redress a breach is not fatal to section 7 claims.[65]
With this background established, Justice Rennie held that the courts below had erred in striking the section 7 claims on the basis that they were claims for the recognition of positive rights. The Misdzi Yikh claim alleged a direct and ongoing deprivation of security of the person related to specific state actions that affected the plaintiffs’ food security, culture, and economies.[66] While the youth plaintiffs’ claim in La Rose was more prospective in nature, it could be read to allege deprivations of “the fruits of Canada’s legislated commitments”[67] towards climate change, causing psychological distress.[68] Although in Mathur the Ontario Superior Court of Justice (ONSC) found that any deprivation of life, liberty, or security of the person in Ontario’s response to climate change was not shown to be contrary to the principles of fundamental justice, this ruling followed a full trial on the merits.[69] Citing the Supreme Court’s GGPPA Reference,[70] Justice Rennie noted that climate change constitutes “an existential challenge, a threat of the highest order to the country, and to the future of humanity which cannot be ignored.”[71] This amounted to the type of “special circumstance” that should allow a section 7 claim to proceed,[72] albeit with amendments to the pleadings required.[73]
Justice Rennie also disagreed with the government’s argument that “a causal relationship between the legislation and the deprivation of a section 7 interest is “manifestly incapable of being proven.””[74] The task is not to prove that “the challenged law or government action”[75] is “the sole or dominant course [sic] of the alleged deprivation,” but more simply that there is “a real as opposed to speculative link.”[76] This is important bearing in mind the proliferation of Charter-based climate litigation in several provinces, including most recently in Saskatchewan.[77] No single government’s legislation and related GHG emissions — whether federal or provincial — will be the sole or even dominant cause of climate change. But as noted by the Supreme Court in the GGPPA Reference, each “province’s emissions are clearly measurable and contribute to climate change.”[78]
Justice Rennie’s handling of section 7 is commendable, but we are disappointed in his reasons on section 15, and indeed the two sets of reasons are difficult to reconcile. Under section 7, it is the current and ongoing impact of climate change in the form of psychological distress that allows the claim to proceed,[79] and this perspective could also have been applied to section 15. If we accept that it is at least arguable that serious anxiety about government (in)action on climate change is experienced disproportionately by youth, or that youth experience qualitatively different distress than the rest of the population, this should have been sufficient to allow the section 15 claim to proceed.[80]
Justice Rennie stated that the question before him was “whether it is reasonably arguable that this reality [viz the adverse impact of climate change on the plaintiffs] falls within the scope of section 15.”[81] He did not apply the two-part test for assessing section 15 claims that he had set out to determine if the claim was within the scope of section 15.[82] Instead, he held that the adverse impact of climate change on the plaintiffs “is not the kind of adverse effect that section 15 is to address”[83] and that “intergenerational equity is not within the scope of section 15, as the law currently stands.”[84] These are conclusions rather than reasons. Justice Rennie did provide a reason, but it was an “underlying rationale” for excluding this claim from section 15’s scope rather than a failure to meet the test for assessing section 15 claims: namely, the separation of powers.[85] This is an underlying rationale that sounds a lot like justiciability, which Justice Rennie had already dealt with.[86] He had already decided that the claim was justiciable, which means he had decided that the court did have the institutional capacity and legitimacy to adjudicate the claim. His conclusion on the justiciability issue is difficult to reconcile with his stated reason for finding that it was not reasonable to argue that this claim fell within the scope of section 15.
In addition, his reliance on the judiciary’s inability to participate “in the policy choices around resource allocation”[87] depended on the discrimination being caused solely by future inequalities. It is disconcerting to see Justice Rennie accept that the claimants might have suffered current harm for the purpose of a section 7 claim[88] while characterizing the same harm as anticipated future harm in the section 15 analysis. In particular, the pleadings in Misdzi Yikh described “a direct deprivation of their security of the person”[89] happening today and not simply concerns about how the legislation would affect them when they are older, which was how Justice Rennie framed the section 15 claim.[90]
In the same vein, it is troubling to see the government’s obligations downplayed under section 15 while being accepted as arguable under section 7, which is unfortunately a result of recent jurisprudence on positive obligations under section 15.[91] At the same time, the Supreme Court of Canada recently recognized that section 15 claims have often taken a backseat when multiple Charter sections are raised, and directed courts that “[t]he Charter should not be treated as if it establishes a hierarchy of rights in which s. 15 occupies a lower tier.”[92] This principle should have allowed the section 15 claim to proceed to trial. To the extent that Justice Rennie found “there are often solid grounds”[93] for the government to treat different age groups differently, these are considerations for section 1 of the Charter. A trial would have been the appropriate forum for the government to justify its climate-related (in)actions.
Finally, Justice Rennie seems to have been unduly dismissive of the principle of intergenerational equity, suggesting that it need not be taken seriously, apparently because of his perception of the limited recognition of the principle.[94] This is misleading. The principle is referenced in numerous international instruments, including the Framework Convention on Climate Change.[95] Thus it is far from clear how he so readily reaches the conclusion that this acceptance “does not yet create a place in the framework under section 15 that would allow the youth appellants’ claim to proceed.”[96]
CONCLUSION
We end by repeating the Supreme Court of Canada’s observation in the GGPPA Reference that climate change presents “an existential challenge…a threat of the highest order to the country, and…to the future of humanity [which] cannot be ignored.”[97] And yet, given short-term election cycles, governments are often reluctant to take stringent measures where the burden falls on the current generation of voters. It is far easier to punt the issue to future generations of voters.[98] The question at the heart of climate change litigation is the question of whether it is lawful for governments to sit on their hands or to prescribe half-hearted measures. Or, as Justice Vermette put it in Mathur, “[t]he issue [is] whether Ontario has a constitutional obligation to take steps to reduce GHG in the province at a rate higher than the [current statutory target].”[99] We applaud the Federal Court of Appeal for recognizing that this issue engages section 7 of the Charter, and only wish it had gone further to recognize the equality rights engaged by the claims in La Rose and Misdzi Yikh.
The last decade has seen an explosion of domestic climate change litigation around the world and an equally rich body of academic literature examining the case law from a variety of disciplinary perspectives. The Sabin Center for Climate Change Law maintains an excellent data base[1] covering these developments. Important cases in other jurisdictions include the Urgenda decision[2] and Shell[3] decision in the Netherlands, and the 2021 decision of the German constitutional court[4]. Australian environmental non-governmental organizations (ENGOs) have been particularly active in bringing climate change issues before the courts, especially in the context of proposed natural gas and coal projects, most famously in the Sharma case[5].
These cases have different doctrinal and theoretical bases. Some are based on domestic constitutional law; some on the domestic implementation of international human rights treaties; and some, like Sharma, on principles of tort law. And while ENGOs have been met with significant successes, there have also been significant setbacks — perhaps most surprisingly in Norway.[6]
Within this broader global context, climate change litigation in Canada, especially rights-based litigation, has been slow to emerge, but with the La Rose[7] decision of the Federal Court of Appeal (the subject of this article) and the Mathur[8] case in the Ontario courts, we are starting to see some engagement. In Mathur v Ontario,[9] and Mathur v His Majesty the King in Right of Ontario,[10] the applicants challenged Ontario’s greenhouse gas emissions reduction target as contrary to section 7 (the right to security of the person) and section 15 (the right to equality) of the Canadian Charter of Rights and Freedoms.[11] The application was permitted to proceed to a hearing on the merits after surviving the Ontario government’s motion to strike, but was unsuccessful at trial. Justice Marie-Andrée Vermette of the Ontario Superior Court of Justice ultimately concluded that there was no violation of section 7 since the “[a]pplicants have not demonstrated that any deprivation of their rights under section 7 of the Charter was contrary [to] the principles of fundamental justice…”[12] Neither was there a breach of section 15, principally because any disproportionate impact that would be experienced by the applicants as youth would be caused by climate change itself and not by Ontario’s greenhouse gas reduction target.[13] The applicants’ appeal was heard by the Ontario Court of Appeal in January 2024 and judgment was reserved.
The La Rose plaintiffs are 15 children and youth residing in seven provinces and one territory. In this case, the target is the federal government. The plaintiffs allege that the government’s failure to address the problem of climate change constitutes a breach of sections 7 and 15 of the Charter. The La Rose plaintiffs also allege that Canada is in breach of its public trust duties, in particular its duty “to preserve and protect inherently public resources — bodies of water, the air, and the permafrost — so that current and future generations may access, use, and enjoy these resources.”[14] The plaintiffs’ requests for relief — discussed in the Federal Court decision considering the government’s motion to strike — included “an order requiring the Defendants to develop and implement an enforceable climate recovery plan that is consistent with Canada’s fair share of the global carbon budget plan to achieve GHG emissions reductions compatible with the maintenance of a Stable Climate System”.[15] The plaintiffs referred to a Stable Climate System as a climate “capable of sustaining human life and liberties.”[16] Justice Michael Manson of the Federal Court granted Canada’s motion to strike principally on the basis that the claims were not justiciable. On appeal, in a unanimous judgment written by Justice Donald Rennie, the Federal Court of Appeal affirmed the motion to strike in relation to the section 15 claim but allowed the appeal in respect of the plaintiffs’ section 7 claim — at least to the extent that the Court gave the parties leave to amend their pleadings.[17]
Justice Rennie’s judgment also provides the Court’s reasons for the appeal in the companion case of Misdzi Yikh v Canada.[18] This was a case brought by two Wet’suwet’en House groups represented by their Dini Ze’ (Head Chiefs) alleging that the federal government’s actions in relation to climate change amounted to a breach of sections 7 and 15 of the Charter and a failure by Canada to make laws in relation to peace, order and good government. Justice Glennys McVeigh of the Federal Court had struck the Misdzi Yikh claim in its entirety.[19]
Justice Rennie found that the section 7 Charter claim could proceed with amended pleadings here too.
This article begins with, and focuses on, Justice Rennie’s reasons for decision in the La Rose case but we also offer some comments on the Misdzi Yikh case.
THE TEST FOR A MOTION TO STRIKE
A claim should be struck if it is plain and obvious that the claim has no reasonable prospect of success. In applying this standard, “the facts are to be taken as proven unless they are manifestly incapable of proof…the pleading must be read generously and, recognizing that the law is not static and evolves to address new and emerging situations, the court must err on the side of permitting novel but arguable claims to proceed to trial…”[20]
JUSTICIABILITY
Justice Rennie noted several possible bases for striking the claims: non-justiciability, failure to disclose a reasonable cause of action, or a failure of the pleadings.[21] A claim is justiciable if a court has both the institutional capacity (what a court can do) and legitimacy to adjudicate the matter (what a court ought to do). A question is justiciable in a constitutional case if it concerns the validity of government (in)actions rather than the wisdom of the choices made by Parliament. Questions as to the wisdom of actions or inactions are issues to be determined by the legislative or executive branches of government within a Westminster parliamentary system rather than the judicial branch.[22] A claim is not rendered non-justiciable just because it concerns matters that are politically sensitive or controversial so long as the claim has a sufficient legal component.[23]
In applying these tests in the La Rose case, Justice Rennie concluded that the plaintiffs’ claims were justiciable. He noted that the question of climate change was not simply a matter of political choice since it had been crystallized into law. Here, Justice Rennie referenced[24] the preamble of the Greenhouse Gas Pollution Pricing Act,[25] which in turn references Canada’s commitment to achieve its Nationally Determined Contribution under the Paris Agreement.[26] Furthermore, “[i]t must not be forgotten that the target of the appellants’ claims is legislation — existing laws, regulatory instruments and Orders in Council.”[27] It followed that there is, “therefore, a sufficient legal component to their claims, and the claims satisfy the legitimacy portion of a justiciability analysis.”[28]
In reaching this conclusion, Justice Rennie was able to distinguish the decision in Friends of the Earth v Canada (Governor in Council).[29] As Justice Rennie noted,[30] Friends of the Earth was a case in which the conclusion as to non-justiciability largely turned on the determination that Parliament allocated the accountability mechanisms in the Kyoto Protocol Implementation Act,[31] to Parliament itself and not to the courts. We agree with this assessment and also agree that Friends of the Earth cannot “stand for the proposition that all claims addressing climate change are inherently non-justiciable.”[32]
While this analysis revealed a sufficient legal target, it was also necessary to assess whether that target was too diffuse and whether a court had the institutional competence to tailor “effective, enforceable remedies to meaningfully address the asserted harms.”[33] Here, Justice Rennie cautioned that a court should be slow to conclude that the remedies sought might render a claim non-justiciable. After all, the courts have the capacity to issue a suspended declaration as a response to unconstitutional behaviour so as to afford the legislative branch the opportunity to respond.[34] In addition, climate change science has been evolving so as to allow “a science-based GHG reduction target,” meaning that “a stable climate system could be established through expert evidence” at trial.[35] This is an important acknowledgement of the concept of a Stable Climate System even though Justice Rennie does not expressly refer to the idea of a carbon budget. Justice Rennie went on to note that requests for remedies are often amended in the course of litigation and while some of the plaintiffs’ requests for remedies might be overly prescriptive or overly general, there would still be the opportunity to tailor remedies appropriately should a breach be found.[36]
In sum, the claims in La Rose were found to be justiciable and the same conclusion must presumably apply to the claims in Misdzi Yikh. This is a significant conclusion, fully in line with the case law in other jurisdictions and with Mathur. In our view, it would be a very strange and unfortunate outcome if rights-based climate change cases were justiciable in other jurisdictions but not here in Canada.
PLAIN AND OBVIOUS AND THE SUBSTANTIVE LAW
With the threshold issue of justiciability disposed of, Justice Rennie could turn to the substantive law underlying the specific claims of the plaintiffs to see if they would falter under the plain and obvious test for failing to disclose a reasonable cause of action. First up was the non-Charter public trust argument of the youth plaintiffs.
THE PUBLIC TRUST CLAIM
The public trust doctrine does not have the salience in Canadian law generally, or in Canadian constitutional law specifically, that it does in the United States. For this reason alone, it is hardly surprising that Justice Rennie declined to interfere with Justice Manson’s conclusion that the plaintiffs’ claim did not disclose a reasonable cause of action.[37] Justice Rennie found that the government’s standing (or power) to act in the public interest did not translate into a general obligation for it to do so.[38] This does not mean that all public trust claims are doomed to failure, but any effort to apply such a doctrine across the whole of the federal government was a leap too far. Better to build this doctrine incrementally — the methodology of the common law — rather than proclaiming a brave new world.
THE POGG CLAIM OF THE MISDZI YIKH PLAINTIFFS
The next issue Justice Rennie addressed was the claim of the Misdzi Yikh plaintiffs in relation to the federal government’s peace, order and good government (POGG) power. Similar to the public trust doctrine, the plaintiffs faced the challenge of converting a federal power to make certain types of laws into a duty to make a law co-extensive with the power (and a correlative right of the plaintiffs to see that such a law would be enacted). That is no small undertaking, and much like our comments above with respect to the public trust doctrine, this is not the case in which to try to use POGG to convert a legislative power into a justiciable duty to act. If there is such a duty, it must arise from the rights-conferring terms of the Charter, not from the language of the power to make laws, or from principles of federalism. In other words, POGG does not supply a free-standing cause of action, but if the plaintiffs can establish a Charter basis for protective measures, then it does seem possible that a court might be able to order federal action, even if that requires the federal government to rely on its POGG power. After all, insofar as it is provincial inability that feeds the POGG power,[39] the federal government might be the only government with the power to take the necessary protective action. But in this case, the Misdzi Yikh plaintiffs do not seem to have expressly combined their POGG and Charter arguments.
Hence, we agree with Justice Rennie’s conclusions striking the POGG claim,[40] but we do caution that his comments with respect to reliance on comparative and international jurisprudence need to be interpreted in context, as we elaborate in the next paragraph.
The Misdzi Yikh plaintiffs based their case on the Bancoult or Chagos Islands decisions of the UK courts,[41] which considered whether the British government’s POGG powers extended to the executive’s politically motivated removal of the inhabitants of the British Indian Ocean Territory. Justice Rennie dismissed any reliance on these cases in terms of the merits of the arguments but also more broadly reasoned as follows:
In any event, constitutional analysis is principally informed by Canadian jurisprudence, which is in turn shaped by our political and social history and only draws upon decisions of foreign courts or principles of international or comparative law in exceptional circumstances (Quebec (Attorney General) v. 9147-0732 Québec inc., 2020 SCC 32, [2020] 3 S.C.R. 426 at paras. 43–47). This practice is driven by the obvious reality that measures adopted in other contexts may be of scant relevance, a point particularly apposite in respect of the Bancoult decisions.[42]
While we generally agree with this sentiment when it comes to questions of division of powers, and specifically the interpretation of POGG in the context of principles of Canadian federalism, we fundamentally disagree with this sentiment as applied to rights-based litigation (and the Charter) in the context of climate change litigation. Insofar as much of this litigation is rooted in an internationally shared set of human rights norms, we think that both international and comparative jurisprudence (as outlined in our introductory paragraphs) should be of considerable interest and value to Canadian courts. We note that both the Supreme Court of Canada in the GGPPA Reference,[43] and Justice Vermette in the Mathur case[44] seem to be much more open to engaging with this jurisprudence.
There is also one more specific reason for engaging with international law in the context of Indigenous plaintiffs and climate law, and that is because of the jurisprudence of the UN Human Rights Committee on article 27 (the minority rights provision) of the International Covenant on Civil and Political Rights.[45] This jurisprudence is important because of the Committee’s insistence that article 27 (even though framed negatively) may in some circumstances require a state party to take positive measures to ensure that Indigenous minorities continue to have access to the material elements of their culture.[46] Given the judicial reluctance to interpret Charter rights as imposing a government duty to take positive protective measure to ensure the enjoyment of the right (see the discussion below), this jurisprudence supports a more generous reading of rights as more than just protections against the state.
CHARTER CLAIMS
This brings us to the plaintiffs’ Charter claims. Justice Rennie began with the equality guarantee in section 15 and the youth plaintiffs’ argument that climate change affects them disproportionately, with the lack of a robust legislative response amounting to adverse effects discrimination based on age. As noted by the Court, a violation of section 15 is assessed via a two-step test: (1) “whether the law or state action creates a distinction [or has a disproportionate impact] based on an enumerated or analogous ground,”[47] and (2) “whether the law or state action imposes burdens or denies a benefit in a manner that perpetuates, reinforces, or exacerbates some disadvantage experienced by the group, either systemically or historically.”[48]
At the outset of his analysis, Justice Rennie recognized that “[c]limate change is having a dramatic, rapidly unfolding effect on all Canadians and on northern and Indigenous communities in particular”[49] and that it is “beyond doubt that the burden of addressing the consequences will disproportionately affect Canadian youth.”[50] While accepting the principle that where the government has conferred a benefit or imposed a burden, it must do so without discrimination, Justice Rennie also noted that governments are “free to address inequality incrementally”[51] and do not have a “freestanding positive obligation…to enact benefit schemes to redress social inequalities.”[52] He characterized the plaintiffs’ claim as one related to future inequalities and intergenerational inequity, and found that it was not the proper role of the courts to address such harms.[53] Justice Rennie noted that age discrimination claims are unique in that age is experienced universally and it is accepted that government actions “will, of necessity, affect different generations differently.”[54] Although the international community is beginning to recognize youth climate rights and intergenerational equity, obligations such as those flowing from the Convention on the Rights of the Child[55] did not factor into the section 15 framework in a manner that would support the plaintiffs’ argument.[56] Justice Rennie upheld the decision to strike the plaintiffs’ section 15 claims without any leave to amend.
This left the section 7 claims, which were to be assessed on the basis of: (1) whether the law or state action deprived the plaintiffs of their life, liberty or security of the person, and (2) whether this deprivation was contrary to the principles of fundamental justice.[57] Justice Rennie also noted the need for the pleadings to draw a sufficient causal connection between the impugned state action and the prejudice suffered by the plaintiffs.[58]
Justice Rennie’s analysis of positive versus negative rights, focused on the idea that section 7 protects against the deprivation of life, liberty, and security of the person by the state, rather than providing a right to a legislative regime or state action that furthers these interests.[59] That said, he acknowledged that the Supreme Court and lower courts have left the door open on the argument that section 7 might encompass positive rights claims in special circumstances, an approach that is particularly important for recognizing Canada’s international human rights obligations.[60] Justice Rennie also noted that it is well accepted that the dividing line between positive and negative rights can be difficult to draw[61] and that the positive/negative orientation of a right might simply depend on the perspective taken.[62] He used an excellent example to illustrate this point, referring to the right to accessibility for persons with disabilities who require assistive devices, “but only because the state has constructed inaccessible programs and infrastructure.”[63]
In the environmental law context, it is useful to recall that, prior to the expansion of the modern environmental state, the common law’s position was that “[p]ollution is always unlawful and, in itself, constitutes a nuisance.”[64] Subsequently, modern environmental laws were passed to broadly prohibit environmental harms in one breath, but also to open the door to regulatory (i.e., statutory) authorization of such harms in the next. In other words, like the disability example where Justice Rennie noted the state’s construction of inaccessible programs and infrastructure, so too has the state authorized climate-destabilizing industries and activity that now threaten the plainitffs’ Charter rights.
Justice Rennie also found that the requirement that the state expend funds to redress a breach is not fatal to section 7 claims.[65]
With this background established, Justice Rennie held that the courts below had erred in striking the section 7 claims on the basis that they were claims for the recognition of positive rights. The Misdzi Yikh claim alleged a direct and ongoing deprivation of security of the person related to specific state actions that affected the plaintiffs’ food security, culture, and economies.[66] While the youth plaintiffs’ claim in La Rose was more prospective in nature, it could be read to allege deprivations of “the fruits of Canada’s legislated commitments”[67] towards climate change, causing psychological distress.[68] Although in Mathur the Ontario Superior Court of Justice (ONSC) found that any deprivation of life, liberty, or security of the person in Ontario’s response to climate change was not shown to be contrary to the principles of fundamental justice, this ruling followed a full trial on the merits.[69] Citing the Supreme Court’s GGPPA Reference,[70] Justice Rennie noted that climate change constitutes “an existential challenge, a threat of the highest order to the country, and to the future of humanity which cannot be ignored.”[71] This amounted to the type of “special circumstance” that should allow a section 7 claim to proceed,[72] albeit with amendments to the pleadings required.[73]
Justice Rennie also disagreed with the government’s argument that “a causal relationship between the legislation and the deprivation of a section 7 interest is “manifestly incapable of being proven.””[74] The task is not to prove that “the challenged law or government action”[75] is “the sole or dominant course [sic] of the alleged deprivation,” but more simply that there is “a real as opposed to speculative link.”[76] This is important bearing in mind the proliferation of Charter-based climate litigation in several provinces, including most recently in Saskatchewan.[77] No single government’s legislation and related GHG emissions — whether federal or provincial — will be the sole or even dominant cause of climate change. But as noted by the Supreme Court in the GGPPA Reference, each “province’s emissions are clearly measurable and contribute to climate change.”[78]
Justice Rennie’s handling of section 7 is commendable, but we are disappointed in his reasons on section 15, and indeed the two sets of reasons are difficult to reconcile. Under section 7, it is the current and ongoing impact of climate change in the form of psychological distress that allows the claim to proceed,[79] and this perspective could also have been applied to section 15. If we accept that it is at least arguable that serious anxiety about government (in)action on climate change is experienced disproportionately by youth, or that youth experience qualitatively different distress than the rest of the population, this should have been sufficient to allow the section 15 claim to proceed.[80]
Justice Rennie stated that the question before him was “whether it is reasonably arguable that this reality [viz the adverse impact of climate change on the plaintiffs] falls within the scope of section 15.”[81] He did not apply the two-part test for assessing section 15 claims that he had set out to determine if the claim was within the scope of section 15.[82] Instead, he held that the adverse impact of climate change on the plaintiffs “is not the kind of adverse effect that section 15 is to address”[83] and that “intergenerational equity is not within the scope of section 15, as the law currently stands.”[84] These are conclusions rather than reasons. Justice Rennie did provide a reason, but it was an “underlying rationale” for excluding this claim from section 15’s scope rather than a failure to meet the test for assessing section 15 claims: namely, the separation of powers.[85] This is an underlying rationale that sounds a lot like justiciability, which Justice Rennie had already dealt with.[86] He had already decided that the claim was justiciable, which means he had decided that the court did have the institutional capacity and legitimacy to adjudicate the claim. His conclusion on the justiciability issue is difficult to reconcile with his stated reason for finding that it was not reasonable to argue that this claim fell within the scope of section 15.
In addition, his reliance on the judiciary’s inability to participate “in the policy choices around resource allocation”[87] depended on the discrimination being caused solely by future inequalities. It is disconcerting to see Justice Rennie accept that the claimants might have suffered current harm for the purpose of a section 7 claim[88] while characterizing the same harm as anticipated future harm in the section 15 analysis. In particular, the pleadings in Misdzi Yikh described “a direct deprivation of their security of the person”[89] happening today and not simply concerns about how the legislation would affect them when they are older, which was how Justice Rennie framed the section 15 claim.[90]
In the same vein, it is troubling to see the government’s obligations downplayed under section 15 while being accepted as arguable under section 7, which is unfortunately a result of recent jurisprudence on positive obligations under section 15.[91] At the same time, the Supreme Court of Canada recently recognized that section 15 claims have often taken a backseat when multiple Charter sections are raised, and directed courts that “[t]he Charter should not be treated as if it establishes a hierarchy of rights in which s. 15 occupies a lower tier.”[92] This principle should have allowed the section 15 claim to proceed to trial. To the extent that Justice Rennie found “there are often solid grounds”[93] for the government to treat different age groups differently, these are considerations for section 1 of the Charter. A trial would have been the appropriate forum for the government to justify its climate-related (in)actions.
Finally, Justice Rennie seems to have been unduly dismissive of the principle of intergenerational equity, suggesting that it need not be taken seriously, apparently because of his perception of the limited recognition of the principle.[94] This is misleading. The principle is referenced in numerous international instruments, including the Framework Convention on Climate Change.[95] Thus it is far from clear how he so readily reaches the conclusion that this acceptance “does not yet create a place in the framework under section 15 that would allow the youth appellants’ claim to proceed.”[96]
CONCLUSION
We end by repeating the Supreme Court of Canada’s observation in the GGPPA Reference that climate change presents “an existential challenge…a threat of the highest order to the country, and…to the future of humanity [which] cannot be ignored.”[97] And yet, given short-term election cycles, governments are often reluctant to take stringent measures where the burden falls on the current generation of voters. It is far easier to punt the issue to future generations of voters.[98] The question at the heart of climate change litigation is the question of whether it is lawful for governments to sit on their hands or to prescribe half-hearted measures. Or, as Justice Vermette put it in Mathur, “[t]he issue [is] whether Ontario has a constitutional obligation to take steps to reduce GHG in the province at a rate higher than the [current statutory target].”[99] We applaud the Federal Court of Appeal for recognizing that this issue engages section 7 of the Charter, and only wish it had gone further to recognize the equality rights engaged by the claims in La Rose and Misdzi Yikh.
