On July 1, 1867, with the coming into force of the British North America Act (enacted by the British Parliament), the Province of Canada, New Brunswick, and Nova Scotia became a federated kingdom in its own right.[37][38] The term dominion was chosen to indicate Canada's status as a self-governing colony of the British Empire, the first time it was used in reference to a country.

I should have clarified, we have not had to defend our border since confederation in 1867, 142 years.
