Today marks the 150th anniversary of the formation of the Dominion of Canada. The British North America Act, which served as Canada’s constitution until the constitution was “patriated” with the Canada Act of 1982, was approved by the British Parliament in February 1867, and received the assent of Queen Victoria on March 29, 1867, with an effective date of July 1, 1867. The Act united the colonies of Canada (which was divided into Ontario and Quebec), Nova Scotia, and New Brunswick.
