Area code 450 surrounds the island of Montreal in Quebec and serves the North and South Shores, including cities like Laval, Longueuil, Brossard, and Saint-Jérôme. Established in 1998, it was created as a split from the 514 area code to serve the rapidly expanding suburbs. The 450 area includes both affluent communities and growing industrial zones. Laval is Quebec’s third-largest city and a major center for biotech, commerce, and education. Longueuil and Brossard feature booming residential development, shopping centers, and a growing immigrant population. The region is largely French-speaking and serves as a bridge between urban Montreal and rural Quebec. A 450 number allows businesses to establish a local identity just outside Montreal’s core, making it ideal for tradespeople, contractors, retailers, and healthcare providers serving the suburban belt.
