Ontario v. Canada re Greenhouse Gas Pollution Pricing Act, 2019
Principle law(s): Greenhouse Gas Pollution Pricing Act
Side A: Province of Ontario (Government)
Side B: Canada (Government)
Side C: Governments of Saskatchewan, New Brunswick, and British Columbia (Government)
Ontario alleges that Parliament exceeded its constitutional authority in passing the GGPPA, arguing that the GGPPA is not authorized by the "national concern branch of the peace, order, and good government power" because the provinces are capable of regulating greenhouse gas emissions themselves and that "there is no need to expand the scope of federal jurisdiction to impose a one-size-fits-all federal carbon price." Ontario further argues that even if the GGPPA falls within the scope of a national concern, the GGPPA represents an unconstitutional tax because it does not provide an adequate nexus between the charges it imposes and its regulatory purpose. Multiple parties have intervened in the case, including a number of advocacy groups and the governments of Saskatchewan, New Brunswick, and British Columbia.
