Ontario v. Canadian Pacific Railway

Ontario v. Canadian Pacific Railway was a legal case where the province of Ontario challenged the railway company's use of certain land. Ontario argued that the railway's actions infringed on provincial rights and land use regulations. The core issue was whether the federal government or the provincial government had authority over land and transportation matters. The Supreme Court ultimately clarified the division of powers, emphasizing that while railways are national in scope, provincial governments also have regulatory authority over land use and environmental issues related to those lands. The case helped define the balance of federal and provincial powers in Canada.
