Since 1958, the Canadian government has used the celebration of 1 July to promote particular models of national identity and to foster national unity. Commemorating the anniversary of Confederation, these Dominion Day and Canada Day (as renamed in 1982) observances changed over the decades to reflect changing government public policy objectives and new conceptions of the nation. From a celebration rooted in military pageantry stressing Canada's British heritage, these events were modified to promote a vision of a multicultural, bilingual country with a strong Aboriginal component. Moreover, Canada Day messages increasingly stressed the themes of individual achievement and respect for diversity. Although politicians played roles in determining the form and content of these events, and public response influenced which components were maintained, bureaucrats working in the Secretary of State department exercised a particularly strong influence on these celebrations, providing institutional continuity and expertise to planning efforts. These celebrations provide a key window into understanding the Canadian government's evolving cultural and national identity policies in the post–Second World War era.
