"Vive le Québec libre!" (French: [vivᵊ ləkebɛk ˈlibʁᵊ], "Long live free Quebec!") was a controversial phrase in a speech delivered by President Charles de Gaulle of France on July 24, 1967, during an official visit to Canada under the pretext of attending Expo 67 in Montreal, Quebec. While giving an address to a large crowd from a balcony at Montreal City Hall, he uttered "Vive Montréal; Vive le Québec !" ("Long live Montreal, Long live Quebec!") and then added, followed by loud applause, "Vive le Québec libre !" ("Long live free Quebec!") with particular emphasis on the word 'libre'. The phrase, a slogan used by Quebecers who favoured Quebec sovereignty, and de Gaulle's use of it, was seen by them as giving his support to the movement. The speech sparked a diplomatic incident with Canada's government, and was condemned by Prime Minister Lester B. Pearson, saying that "Canadians do not need to be liberated". In France, though many were sympathetic to the cause of Quebec nationalism, de Gaulle's speech was criticized by much of the media as being a breach of protocol. Over four decades later, it is still seen as a turning point in English and French Canadian relations and politics.
Even before his arrival, the Canadian federal government had been concerned about President de Gaulle's visit. Earlier that year, the French government had not sent a high-level representative to the funeral service for Governor General Georges Vanier. This attracted notice in Canada, as Vanier and his wife, Pauline, had been personal friends of de Gaulle since 1940, when the latter was in exile in London, England. In April, de Gaulle did not attend the 50th anniversary ceremonies commemorating the Canadian victory at Vimy Ridge. So worried was the Pearson government about potential interference of France in domestic affairs that Secretary of State for External Affairs, Paul Martin, was dispatched to visit de Gaulle in Paris to mend the two countries' relationship. It was speculated by The Montreal Gazette, 45 years after the incident, that De Gaulle was still annoyed over a perceived slight from World War II-era Canadian Prime Minister Mackenzie King's slow recognition of the new French government in late summer 1944.
