Later in 2018, Ontario, Alberta and Manitoba all withdrew their support from the <em>Pan-Canadian Framework<\/em>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The legislation at issue: <em>GGPPA<\/em><\/h2>\n\n\n\n<p>The <em>Pan-Canadian Framework<\/em> required every province and territory to implement a carbon tax or a cap-and-trade system by 2018. In June 2018, the <em>GGPPA<\/em> came into force, and the federal government imposed carbon pricing regimes in provinces and territories with insufficiently stringent GHG pricing mechanisms.<\/p>\n\n\n\n<p>The <em>GGPPA <\/em>is comprised of four parts and four schedules as follows:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Part 1: Establishes a regulatory charge on GHG-emitting fuels that applies to producers, distributors and importers;<\/li>\n\n\n\n<li>Part 2: Creates a pricing mechanism for GHG emissions by large industrial facilities;<\/li>\n\n\n\n<li>Part 3: Authorizes the Governor in Council to regulate the application of provincial emissions laws over federal matters; and<\/li>\n\n\n\n<li>Part 4: Requires the Minister of the Environment to prepare and table an annual report on the administration of the <em>GGPPA<\/em>.<\/li>\n<\/ul>\n\n\n\n<p>As CJ Wagner notes, Parts 1 and 2 of the <em>GGPPA<\/em> \u201ctogether create a single GHG pricing scheme.\u201d<a href=\"#_ftn4\" name=\"_ftnref4\">[4]<\/a> The constitutionality of Parts 3 and 4 of the <em>GGPPA <\/em>were not at issue.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The constitutional challenges<\/h2>\n\n\n\n<p>The Attorney Generals of Alberta, Ontario and Saskatchewan each challenged the constitutionality of Parts 1 and 2 (and the 4 schedules) of the <em>GGPPA <\/em>on the grounds that the law overstepped the federal government\u2019s jurisdiction.<\/p>\n\n\n\n<p>While majorities at the Saskatchewan and Ontario Court of Appeals each upheld the <em>GGPPA<\/em>\u2019s constitutionality, the Alberta Court of Appeal found that the <em>GGPPA<\/em> intruded into the provinces\u2019 exclusive jurisdiction over the development and management of natural resources.<\/p>\n\n\n\n<p>These decisions were appealed to the SCC, where Alberta, Ontario and Saskatchewan continued to challenge the <em>GGPPA<\/em>\u2019s constitutionality<strong>, <\/strong>while Canada and British Columbia argued that the <em>GGPPA<\/em> was constitutional on the basis of the national concern branch of the POGG clause of the&nbsp;<em>Constitution Act, 1867.<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">SCC majority upholds the <em>GGPPA<\/em> as constitutional<\/h2>\n\n\n\n<p>Chief Justice Wagner, writing for a clear majority of the Court, concluded that Parliament has jurisdiction to enact the <em>GGPPA <\/em>as a matter of national concern under the POGG clause<em>. <\/em>A division of powers analysis requires the court to consider the purpose and effects of the challenged statute to identify its primary purpose, or \u201cpith and substance,\u201d before determining whether the law falls within the jurisdiction of the enacting level of government.<\/p>\n\n\n\n<p>The majority held that the <em>GGPPA<\/em>\u2019s pith and substance was to establish minimum national standards of GHG price stringency to reduce GHG emissions. Provinces retained the ability to design any GHG pricing system provided that it met the federal government\u2019s GHG pricing floor.<a href=\"#_ftn5\" name=\"_ftnref5\">[5]<\/a> CJ Wagner acknowledged that this restriction may impact a province\u2019s preferred balance between economic and environmental considerations, but found this impact justified, stating:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p>\u2026it is necessary to consider the interests that would be harmed \u2014 owing to irreversible consequences for the environment, for human health and safety and for the economy \u2014 if Parliament were unable to constitutionally address the matter at a national level. This irreversible harm would be felt across the country and would be borne disproportionately by vulnerable communities and regions, with profound effects on Indigenous peoples, on the Canadian Arctic and on Canada\u2019s coastal regions. In my view, the impact on those interests justifies the limited constitutional impact on provincial jurisdiction.<a href=\"#_ftn6\" name=\"_ftnref6\">[6]<\/a><\/p>\n<\/blockquote>\n\n\n\n<p>The SCC then considered whether the <em>GGPPA<\/em> was a valid exercise of the federal government\u2019s jurisdiction to govern over matters of national concern under the POGG clause of the&nbsp;<em>Constitution Act, 1867. <\/em>The national concern test is three-pronged, and requires Canada to show that the proposed matter:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>is of sufficient concern to Canada as whole;<\/li>\n\n\n\n<li>has a singleness, distinctiveness and indivisibility that clearly distinguishes it from matters of provincial concern; and<\/li>\n\n\n\n<li>has a scale of impact on provincial jurisdiction that is reconcilable with the fundamental distribution of legislative power under the Constitution.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Threshold<\/h3>\n\n\n\n<p>The majority found that establishing minimum national standards of GHG price stringency to reduce GHG emissions readily passes the threshold test, satisfying the first stage of the test. In this regard, CJ Wagner states that climate change is \u201ca threat of the highest order to the country, and indeed to the world,\u201d and implores that \u201c[t]he undisputed existence of a threat to the future of humanity cannot be ignored.\u201d<a href=\"#_ftn7\" name=\"_ftnref7\">[7]<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Singleness, distinctiveness and indivisibility<\/h3>\n\n\n\n<p>The majority held that recognizing minimum national standards of GHG price stringency to reduce GHG emissions as a matter of national concern is a specific and identifiable matter that is qualitatively different from matters of provincial concern.<\/p>\n\n\n\n<p>CJ Wagner also recognizes that \u201ca failure to include one province in the scheme would jeopardize its success in the rest of Canada\u201d for two main reasons.<a href=\"#_ftn8\" name=\"_ftnref8\">[8]<\/a> First, businesses in high-emitting sectors may relocate to jurisdictions with less stringent carbon pricing policies. The environmental consequences of this \u201ccarbon leakage\u201d could leave \u201cCanada\u2019s net emissions unchanged and people across Canada vulnerable to the consequences of those emissions.\u201d<a href=\"#_ftn9\" name=\"_ftnref9\">[9]<\/a> Second, emissions reductions by only a few provinces would fail to address climate change if they were offset by increased emissions in other Canadian jurisdictions. CJ Wagner explicitly rejects the Alberta Court of Appeal\u2019s reasoning that each individual province\u2019s emissions caused \u201cno measurable harm.\u201d<a href=\"#_ftn10\" name=\"_ftnref10\">[10]<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Scale of impact<\/h3>\n\n\n\n<p>The majority held that the matter\u2019s scale of impact on provincial jurisdiction was limited, as the <em>GGPPA<\/em> would impose a backstop pricing system \u201conly to the extent necessary to remedy the deficiency in provincial regulation in order to address the extra-provincial and international harm that might arise from the province\u2019s failure to act or to set sufficiently stringent standards.\u201d<a href=\"#_ftn11\" name=\"_ftnref11\">[11]<\/a> This impact is thereby reconcilable with the division of powers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Key takeaways from the decision<\/h2>\n\n\n\n<p>The SCC\u2019s acknowledgement of the climate crisis, which it states \u201cposes a grave threat to humanity\u2019s future,\u201d underpins its conclusion that the federal government can regulate a carbon pricing scheme.<a href=\"#_ftn12\" name=\"_ftnref12\">[12]<\/a> This decision means that the federal backstop will continue to apply, in part or in full, in Alberta, Saskatchewan, Manitoba, Ontario, New Brunswick, Prince Edward Island, Yukon, and Nunavut. As the constitutionality of the matter is now settled, provincial leaders may re-consider whether to install their own carbon pricing scheme. While Quebec, Nova Scotia, Newfoundland and Labrador, the Northwest Territories, and BC\u2019s carbon pricing schemes all presently meet federal benchmark stringency requirements<strong>, <\/strong>these jurisdictions will need to match federal backstop increases, which are set to rise from $30 per tonne to $170 per tonne by 2030.<\/p>\n\n\n\n<p>Carbon pricing plays a central role in the federal government\u2019s climate plan. By requiring people to pay for certain actions and activities through the carbon pricing scheme, the government hopes to \u201cincentivize individuals and businesses to change their behaviour so as to make more environmentally sustainable purchasing and consumption choices, to redirect their financial investments, and to reduce their GHG emissions by substituting carbon-intensive goods for low-GHG alternatives.\u201d<a href=\"#_ftn13\" name=\"_ftnref13\">[13]<\/a><\/p>\n\n\n\n<p>Canada has committed to reaching net zero emissions by the year 2050. Laws and policies which the federal government enacts to progress towards this goal will undoubtedly face further jurisdictional challenges. The narrow scope of this ruling, which found that the federal government has jurisdiction to establish minimum national standards of GHG price stringency to reduce GHG emissions, does not resolve questions about Parliament\u2019s jurisdictional authority to regulate emissions more broadly.<\/p>\n\n\n\n<p>As a global problem, international efforts are necessary to address climate change. By regulating carbon pricing, the federal government seeks to reduce Canada\u2019s GHG emissions and meet its emissions targets, which will increase its climate credibility in the international community and its ability to push other countries to do the same.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><a href=\"#_ftnref1\" name=\"_ftn1\">[1]<\/a> \u201cGreenhouse Gas Emissions.\u201d <em>Government of Canada<\/em>, last updated 15 April 2020, www.canada.ca\/en\/environment-climate-change\/services\/environmental-indicators\/greenhouse-gas-emissions.html.<\/p>\n\n\n\n<p><a href=\"#_ftnref2\" name=\"_ftn2\">[2]<\/a> <em>Reference re Greenhouse Gas Pollution Pricing Act<\/em>, 2021 SCC 11 at para 24 [<em>GGPPA Reference<\/em>].<\/p>\n\n\n\n<p><a href=\"#_ftnref3\" name=\"_ftn3\">[3]<\/a> \u201cGreenhouse Gas Emissions.\u201d <em>Government of Canada<\/em>, last updated 15 April 2020, www.canada.ca\/en\/environment-climate-change\/services\/environmental-indicators\/greenhouse-gas-emissions.html.<\/p>\n\n\n\n<p><a href=\"#_ftnref4\" name=\"_ftn4\">[4]<\/a> <em>GGPPA Reference<\/em>, at para 38.<\/p>\n\n\n\n<p><a href=\"#_ftnref5\" name=\"_ftn5\">[5]<\/a> <em>GGPPA Reference<\/em>, at paras 65, 80, 206.<\/p>\n\n\n\n<p><a href=\"#_ftnref6\" name=\"_ftn6\">[6]<\/a> <em>GGPPA Reference<\/em>, at para 206.<\/p>\n\n\n\n<p><a href=\"#_ftnref7\" name=\"_ftn7\">[7]<\/a> <em>GGPPA Reference<\/em>, at para 167.<\/p>\n\n\n\n<p><a href=\"#_ftnref8\" name=\"_ftn8\">[8]<\/a> <em>GGPPA Reference<\/em>, at para 183.<\/p>\n\n\n\n<p><a href=\"#_ftnref9\" name=\"_ftn9\">[9]<\/a> <em>GGPPA Reference<\/em>, at para 186.<\/p>\n\n\n\n<p><a href=\"#_ftnref10\" name=\"_ftn10\">[10]<\/a> <em>GGPPA Reference<\/em>, at para 188.<\/p>\n\n\n\n<p><a href=\"#_ftnref11\" name=\"_ftn11\">[11]<\/a> <em>GGPPA Reference<\/em>, at para 200.<\/p>\n\n\n\n<p><a href=\"#_ftnref12\" name=\"_ftn12\">[12]<\/a> <em>GGPPA Reference<\/em>, at para 2.<\/p>\n\n\n\n<p><a href=\"#_ftnref13\" name=\"_ftn13\">[13]<\/a> <em>GGPPA Reference<\/em>, at para 16.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On March 25, 2021, the Supreme Court of Canada (\u201cSCC\u201d) released its decision in the Reference re Greenhouse Gas Pollution Pricing Act, upholding the constitutionality of the Greenhouse Gas Pollution Pricing Act (\u201cGGPPA\u201d).
