Answer:
Federation of colonies
Step-by-step explanation:
Dominion of Canada is a federation of colonies in British North America - New Brunswick, Nova Scotia, Quebec, and Ontario - joined together to become the Dominion of Canada on July 1, 1867.
John A. Macdonald was the dominant creative mind which produced the British North America Act and the union of provinces which became Canada. As the first prime minister of Canada, he oversaw the expansion of the Dominion from sea to sea. His government dominated politics for a half century and set policy goals for future generations of political leaders.
