when did the british north america act take effect
British North America Acts Canada dates its history as a country to the British North America Act, 1867, which came into effect on July 1, 1867. However, Canada was not established as fully independent, since the United Kingdom retained legislative control over Canada and full control over Canadian foreign policy. Canada did not have any foreign embassies until its first one was established in Washington, D.C., in 1931. Until 1949, changes to the British North America Acts could be made only by the British parliament. The British North America (No. 2) Act, 1949, gave the Parliament of Canada the power to make limited constitutional amendments, but full Canadian control over the constitution was not achieved until the passage of the Canada Act 1982. This long delay was in large part due to the inability to agree upon a procedure for making constitutional amendments that was acceptable to all of the provinces, in particular the Province of Quebec.
