Canadian diplomacy has greatly shaped Canada’s debates over language and vice versa. How has the history of Canadian diplomacy reflected the bilingual and bicultural nature of the country? Or, conversely, how have Canada’s debates over language and Quebec nationalism affected Canadian diplomacy? The answers are complex. Francophone diplomats played a key role in pushing for Canadian autonomy from Britain at the 1926 Imperial Conference. As Robert Talbot explained, “Canadian foreign policy was being shaped with French-Canadian and modern Anglo-Canadian priorities in mind.” This role was less prominent over the following three decades but, with the election of the Quebec Liberals in 1960, federal diplomacy became directly challenged by Quebec’s international ambitions. This tension reached a crisis point with the Montreal 1967 visit of General Charles De Gaulle, President of France, and again during the Quebec referendums of 1980 and 1995.
