Definition:

In Canada, the term Confederation refers to the union of the three British North American colonies of New Brunswick, Nova Scotia and Canada to become the Dominion of Canada on July 1, 1867. The three colonies were made into the four provinces of New Brunswick, Nova Scotia, Ontario and Quebec. The other provinces and territories entered Confederation later. (See Entry Into Canadian Confederation.)

Canadian Confederation is sometimes referred to as the "birth of Canada."
