When Newfoundland entered the Canadian Confederation in 1949, it was hoped it would promote greater unity between the Maritime provinces, as Term 29 of the Newfoundland Act explicitly linked the region's economic and political fortunes.

However, Newfoundland's arrival did little at first to bring about a comprehensive Atlantic Canadian regionalism.
