HillNote
This HillNote examines two recent environmental law cases to highlight the different pathways the Supreme Court of Canada may take in determining the constitutionality of environmental legislation. In the first case, References re Greenhouse Gas Pollution Pricing Act, the Supreme Court considered whether the federal government has the authority to pass legislation that puts a price on carbon. The outcome in the case hinged on a rarely used residual power of the Parliament of Canada to make laws on matters of national concern. In the second case, Reference re Impact Assessment Act, the Supreme Court assessed the constitutionality of the federal government’s environmental assessment regime.
