Federal Legislative Authority in Relation to Oil and Gas Development in Canada

The report explains that while provinces have broad authority over natural resources, the Canadian federal government can regulate oil and gas development through various 'heads of power' in the Constitution. It details the legal doctrines used by courts to resolve jurisdictional overlaps, such as 'double aspect' and 'incidental effects,' and analyzes twelve specific federal powers—including criminal law, fisheries, and interprovincial works—that allow the federal government to influence the oil and gas life cycle from production to closure.

• Oil and gas development is not the exclusive domain of provincial authority; the federal government can regulate specific aspects that engage federal legislative powers, such as interprovincial infrastructure projects and the protection of transboundary waterways and fisheries.
• Federal regulations are constitutional if they focus on a federal interest, even if they have 'incidental effects' on provincial matters. These effects are considered secondary to the legislation's primary purpose and do not render a law unconstitutional.
• The federal criminal law power is a significant tool for environmental protection and climate action. Current and proposed regulations on greenhouse gas (GHG) emissions from the electricity sector and oil and gas production are consistent with existing constitutional precedents.
• The federal government possesses broad discretionary power over spending and taxation, which it has historically used to provide financial support and tax incentives to the fossil fuel industry, and can similarly use to remove such support.
• Federal authority over fisheries, specifically the Fisheries Act, serves as a de facto national water quality regime. Section 36 prohibits the deposit of deleterious substances in fish-frequented waters, and Section 35 requires authorizations for the harmful alteration, disruption or destruction (HADD) of fish habitat, which every oil sands mine has required.
• The federal Bankruptcy and Insolvency Act (BIA) may currently incentivize oil and gas companies to ignore environmental liabilities—estimated at $260 billion in Alberta alone—by allowing them to walk away from costs through the bankruptcy process.
• The federal government has comprehensive legislative authority over interprovincial works and undertakings, which includes the regulation of interprovincial oil and gas pipelines, encompassing all social, economic, and environmental considerations.
• The 'Peace, Order, and Good Government' (POGG) power allows the federal government to address matters of 'national concern.' The Supreme Court has upheld the Greenhouse Gas Pollution Pricing Act (GGPPA) on the basis that establishing minimum national standards for GHG price stringency is a matter of national concern.
• Under Section 132 of the Constitution, the federal government can implement Imperial treaties, providing the basis for the Migratory Birds Convention Act, 1994, which has been used to prosecute oil sands operators for bird mortalities in tailings ponds.
