Opinion Commented on: Reference re Impact Assessment Act, 2022 ABCA 165 (CanLII)
PDF Version: Carbon Tax Redux: A Majority of the Alberta Court of Appeal Opines that the Impact Assessment Act is Unconstitutional
On May 10, 2022, the Alberta Court of Appeal released its lengthy and long-awaited opinion in Reference re Impact Assessment Act, 2022 ABCA 165 (CanLII). A majority of the Court of Appeal (Chief Justice Fraser, Justice Watson, and Justice MacDonald) concluded that the Impact Assessment Act, SC 2019, c 28, s 1 (IAA), Part 1 of Bill C-69, was ultra vires (i.e. beyond) Parliament’s legislative authority pursuant to section 91 of the Constitution Act, 1867. Justice Strekaf concurred in the result. Justice Greckol dissented, concluding that the IAA was indeed constitutional. In my view, Justice Greckol’s dissent is both clearer and more consistent with current Canadian constitutional and environmental law doctrine. The majority’s opinion, on the other hand, is relatively difficult to follow, includes basic doctrinal errors in some parts, and ignores or strays far from precedent in others. In this and other ways, the majority’s approach is strongly reminiscent of its earlier opinion in Reference re Greenhouse Gas Pollution Pricing Act, 2020 ABCA 74 (CanLII) (GGPPA Reference ABCA) (see post here), which was overturned by the Supreme Court of Canada in References re Greenhouse Gas Pollution Pricing Act, 2021 SCC 11 (CanLII) (GGPPA References SCC) (see posts here, here, and here). The federal government has already confirmed that it will appeal the majority’s opinion to the Supreme Court, pending which the IAA regime will remain in force (reference opinions not being strictly binding the same way that judgments are).
