What is double majority in Canada?

In Canada, a double majority refers to a voting requirement in certain contexts, particularly in constitutional amendments. It requires not only a majority of votes from the general electorate but also approval from a majority of provinces or territories. This mechanism is designed to ensure that changes to the constitution reflect the consent of both the population and the regional governments, thereby balancing national and provincial interests. The concept is notably applied in the Constitution Act, 1982, particularly for amendments affecting the powers of the provinces.
