MONTREAL - INTRODUCTION Montreal, city, Île-de-Montréal County, southern Quebec Province, Canada, on the Île-de-Montréal (Montreal Island), at the confluence of the St Lawrence and Ottawa rivers. Montreal is Canada's most populous city; its metropolitan area population, however, is second to that of Toronto. Most of Montreal's citizens speak French as their first language. The landscape of Montreal is primarily flat, but encompasses scattered hills, including Mount Royal (233 m/764 ft high), situated in the centre of the city. The area around Mount Royal is densely urbanized, and the population spreads along river arms and trunk roads into the suburbs. The business district is wedged between the St Lawrence River and Mount Royal. High office buildings are concentrated downtown around René Lévesque Boulevard, and large department stores are situated on St Catherine Street. Population 3,480 (2000 estimate).
