Summer time ends in eastern Canada on Sunday 1 November 2026. At 02:00 local time, the clocks go back one hour, to 01:00.^[1] But this year most of western Canada does not change: British Columbia, Alberta, the Northwest Territories, Manitoba and northwestern Ontario now stay on summer time all year.^[2][3]

These places turn their clocks back one hour:^[1]

Most of Ontario and Quebec, for example Toronto, Ottawa and Montréal: from UTC-4 to UTC-5.
New Brunswick, Nova Scotia and Prince Edward Island, for example Halifax: from UTC-3 to UTC-4.
Newfoundland, for example St. John's: from UTC-2:30 to UTC-3:30. Most of Labrador: from UTC-3 to UTC-4.

British Columbia: UTC-7 all year since March 2026.^[4] The East Kootenay region and Golden follow Alberta's time.^[1]
Alberta and the Northwest Territories: UTC-6 all year since 2026.^[1][2]
Manitoba and northwestern Ontario west of 90° west, for example Kenora: UTC-5 all year from November 2026.^[3][5]
Saskatchewan (UTC-6) and Yukon (UTC-7) already kept one time all year.^[1]

British Columbia, Alberta, the Northwest Territories, Manitoba and northwestern Ontario simply keep their summer time: their last clock change was on 8 March 2026, when the clocks went forward.^[1][4]

New time differences this winter

Because only the east changes, some familiar time differences change from Sunday:

Toronto is 2 hours ahead of Vancouver, not 3.
Toronto is 1 hour ahead of Calgary, not 2.
Toronto and Winnipeg have the same time.

The differences with the USA change too: Vancouver is one hour ahead of Seattle, Calgary one hour ahead of Denver, and Winnipeg one hour ahead of Chicago. So a weekly call set in Toronto or New York time starts one hour later in western Canada. More in Clocks go back one hour in the USA. The Canada time zone map shows the time in every province.

Lake Louise in Alberta: a turquoise lake below snowy mountains, with a red canoe — Lake Louise in Alberta. Alberta now keeps the same time all year.

Phones, computers and apps need new time zone data for these changes. Until a device has it, it may show the wrong time in British Columbia, Alberta, the Northwest Territories, Manitoba or northwestern Ontario after 1 November.^[2] Google advises updating the system and apps. In Google Calendar, events after 1 November in these places may appear one hour later than planned; the web version of Calendar offers a one-click fix.^[2]
