Inventing Atlantic Canada is the first book to analyse the reaction of the Maritime provinces to Newfoundland's entry into Confederation. Drawing on editorials, government documents, and political papers, Corey Slumkoski examines how each Maritime province used the addition of a new provincial cousin to fight underdevelopment. Slumkoski also details the rise of regional cooperation characterized by the Atlantic Revolution of the mid-1950s, when Maritime leaders began to realize that by acting in isolation their situations would only worsen.
