The Supreme Court of Canada has delivered a landmark ruling, finding key provisions of the federal Impact Assessment Act unconstitutional. In a 5-2 decision, the court concluded that the law, which assesses major energy and infrastructure projects, oversteps federal authority and infringes on provincial jurisdiction over natural resources. The ruling is a significant victory for Alberta and other provinces that challenged the legislation, often dubbed the "no-pipelines law." The federal government must now rewrite its environmental assessment framework, creating uncertainty for future resource development across Canada.
