The 1970s ushered in a period of wide-ranging social and political changes , stemming largely from the concerns of the French speaking majority about the conservation of their culture and language , given the traditional predominance of the English Canadian minority in the business arena . The October Crisis and the 1976 election of the Parti Québécois , supporting sovereign status for Quebec , resulted in the departure of many businesses and people from the city . In 1976 Montreal was the host of the Olympics . During the 1980s and early 1990s , Montreal experienced a slower rate of economic growth than many other major Canadian cities . Montreal was the site of the 1989 École Polytechnique massacre , Canada 's worst mass shooting , where 25-year-old Marc Lépine shot and killed 14 people , all of them women , and wounding 14 other people before shooting himself at École Polytechnique
