Canada time zones
Canada spans six standard time zones. In 2026 the rules changed in the west: British Columbia moved to permanent daylight time in March, and Alberta adopted year-round “Alberta Time”. Here is every area with its winter and summer offset and the time right now.

Questions people ask
How many time zones does Canada have?
Six standard time zones, from Newfoundland Time (UTC−3:30) in the east to Pacific Time in the west. In 2026 several western provinces stopped changing their clocks, so the exact offsets now depend on the season and the province.
Does all of Canada use daylight saving time?
No. Most of Saskatchewan has never changed its clocks in modern times, and in 2026 British Columbia moved to permanent daylight time (UTC−7) and Alberta adopted permanent “Alberta Time” (UTC−6). The table shows the current rules for every area.
What time zone is Toronto in?
Eastern Time: UTC−5 in winter and UTC−4 in summer, the same as New York.
