1970 - In October, separatist terrorists in Quebec (members of the Front de libération du Québec, the FLQ) kidnapped the British trade commissioner, James Cross, and the provincial labour minister Pierre Laporte. Laporte was later found murdered. Quebec premier Robert Bourassa seemed to hesitate in dealing with the terrorists, influenced by Quebec nationalists who wanted to negotiate with them. Prime Minister Pierre Trudeau responded by invoking the War Measures Act, the first and only time this act has been used in peace time.

Although some people have said that the federal government over-reacted, others were glad of strong action during what were very frightening times. This period has been called the October Crisis.
