Montréal is the largest city in Québec. Predominantly French-speaking, it?s set on an island in the Saint Lawrence River and named after Mt. Royal, the triple-peaked hill at its heart. Its 19 boroughs, many of which were once independent cities, include neighbourhoods from cobblestoned, French colonial Vieux-Montréal ? with imposing Notre-Dame Basilica at its center ? to industrial Sud-Ouest and artist-friendly Plateau.
