The term Canadian federalism refers to the current and evolving structure of Canada's federal government. Including the federal government and the ten individual provinces, Canada has a total of eleven levels of government (Hachard, 2020). The Canadian Constitution is the source of law for Canada's eleven provincial and territorial governments. In this paper, I will focus on Ontario Province which is situated in Eastern Canada near the border. The paper will also cover the impacts of Canadian federalism on cross-border trade and how it has affected different government relations. In relation to this assignment, I chose Ontario because it borders the US and when it comes to producing nickel and platinum group metals, Ontario ranks in the top ten worldwide.
