Canada stretches across six time zones from Newfoundland (UTC−3:30) in the east to British Columbia in the west. Atlantic Canada, Ontario and Quebec still change their clocks on the same dates as the United States, but every province from Manitoba westwards now keeps one time all year: Saskatchewan and Yukon already did, and in 2026 Manitoba, Alberta and British Columbia ended seasonal clock changes too.
Where these times apply
All ten provinces and three territories are included. A few communities follow a neighbouring province’s time; the main exceptions are noted below.
Daylight saving time in Canada
Newfoundland, the Atlantic provinces and most of Ontario and Quebec still change their clocks at 2:00 a.m. local time on the second Sunday of March and the first Sunday of November — the same dates as the US, so Toronto and New York always show the same time.
Saskatchewan has stayed on Central Standard Time all year since the 1960s, and Yukon moved to permanent UTC−7 in 2020. In 2026 three more provinces and a territory stopped: British Columbia stays on UTC−7 (Pacific Time), Alberta and the Northwest Territories on UTC−6 (Alberta Time / Northwest Territories Time), and Manitoba, with Ontario west of 90° W, on UTC−5 (Manitoba Standard Time). All three sprang forward on 8 March 2026 and stay on that time instead of falling back on 1 November 2026. In winter, Vancouver is therefore an hour ahead of Seattle, Calgary an hour ahead of Denver and Winnipeg an hour ahead of Chicago.
The half-hour zone
Newfoundland is one of the few places in the Americas with a half-hour offset. A national TV schedule famously adds “half an hour later in Newfoundland”, and a 9:00 call in Toronto is at 10:30 in St. John’s.
Business hours across Canada
A typical office day is 9:00 to 17:00. The Toronto Stock Exchange opens at 9:30 Eastern Time — 10:30 in Halifax and 11:00 in St. John’s — and closes at 16:00 Eastern.
