The Supreme Court of Canada has delivered a landmark ruling, finding the federal Impact Assessment Act largely unconstitutional. In a 5-2 decision, the court determined the legislation, known as Bill C-69, overstepped federal authority by infringing on exclusive provincial jurisdiction over natural resources and local projects. The judgment represents a significant victory for provinces like Alberta, which challenged the law as an intrusion on their economic sovereignty. The federal government must now redraft the legislation, creating immediate uncertainty for major resource projects while potentially clarifying regulatory pathways in the long term.
