Most of Quebec operates on Eastern Standard Time (EST) during winter months, which is 5 hours behind Coordinated Universal Time (UTC-5). During daylight saving time, observed from the second Sunday in March to the first Sunday in November, Quebec switches to Eastern Daylight Time (EDT), which is UTC-4.
Major cities including Montreal, Quebec City, Laval, and Gatineau all follow Eastern Time. The eastern tip of Quebec (Îles-de-la-Madeleine) observes Atlantic Time (AST/ADT). Quebec shares the same timezone as Ontario and the U.S. East Coast, making business coordination straightforward.
Quebec is the largest Canadian province by area and the only one with French as its sole official language. Montreal is the second-largest French-speaking city in the world after Paris. The province is also known for its maple syrup production, accounting for about 70% of the world's supply.
