Canada Emerges: Dominion Formed Under British North America Act

The British North America Act of 1867 united three colonies into a single Dominion, yet London retained full control over foreign policy and constitutional amendments for over a century. This arrangement prevented Canada from establishing its own embassies until 1931 and blocked provincial agreement on amendment procedures for decades. Full sovereignty finally arrived in 1982 when patriation transferred ultimate constitutional authority to Ottawa, ending the era of British legislative oversight.
