Canada has six time zones, and poll closures are synchronized to happen at roughly the same time nationwide.

The first polls opened in Newfoundland and Labrador, an Atlantic province, at 8:30 a.m. local time, which is 7 a.m. Eastern. Ontario and Quebec, the most populous provinces, which fall in the Eastern time zone, will vote from 9:30 a.m. to 9:30 p.m.

The country’s westernmost province, British Columbia, will close a half-hour later than Ontario and Quebec do, at 10 p.m. Eastern.

(Elections Canada, the nonpartisan agency that administers the federal election, has a complete list of polling hours.)

About 7.3 million Canadians cast their ballots during the early-voting period, April 18 to April 21, according to Elections Canada, a 25 percent increase over early-voting turnout in the 2021 election.
