For more than a decade, uOttawa law professor Nathalie Chalifour has analyzed the constitutionality of federal climate legislation. In February this year, the outside world came knocking, and her expertise was put to the test.
Saskatchewan was challenging the constitutionality of the federal government’s new national carbon pricing legislation, which came into force on April 1, 2019, in provinces lacking their own plans to reduce carbon emissions. The Ecofiscal Commission, acting as an intervenor in support of the federal carbon tax, invited her and Professor Stewart Elgie to represent it in the case before the Saskatchewan Court of Appeal.
