Canada no longer changes its clocks as one country. Time is a provincial matter, and in 2026 the west broke away: British Columbia, Alberta and Manitoba put their clocks forward on 8 March 2026 and left them there, joining Yukon and Saskatchewan. Ontario, Quebec and the Atlantic provinces still follow the United States, forward on the second Sunday in March and back on the first Sunday in November, which in 2027 means 14 March and 7 November. Each province has its own row in the table.

Provinces That Still Change: Ontario, Quebec and the Atlantic

Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island and Newfoundland and Labrador keep the North American dates, as does most of Nunavut. The change is at 2:00 a.m. local time in each zone. Newfoundland adds its own twist: the island runs half an hour ahead of Atlantic time, so St. John's changes at 2:00 a.m. on a clock that is already thirty minutes off everyone else's. Ontario passed a law in 2020 to stay on daylight time permanently, but only if Quebec and New York State do the same, and neither has, so for now Toronto, Ottawa and Montreal change with New York. A small part of eastern Quebec, east of the Natashquan River, stays on Atlantic Standard Time all year.

The West Stopped in 2026

British Columbia had held a public consultation in 2019 in which more than nine in ten respondents wanted to stop changing clocks, and for years it waited for Washington, Oregon and California. In March 2026 it stopped waiting. The spring change of 8 March 2026 was its last, and most of the province is now on Pacific Time fixed at seven hours behind Universal Time. Alberta and Manitoba did not turn their clocks back on 1 November 2026 either. The practical result is new: in winter Vancouver now shows the same time as Denver instead of Seattle, Calgary the same as Chicago, and Winnipeg the same as Toronto, while in summer the familiar pattern returns because the places that still change catch up. Anyone booking winter flights or calls across the Prairies should check the table rather than rely on habit.

Saskatchewan and Yukon: The Ones That Never Moved, and the One That Left First

Saskatchewan has kept Central Standard Time all year since the 1960s, which by the sun is closer to permanent daylight time, since the province lies largely in the Mountain zone. The border city of Lloydminster follows Alberta instead. Yukon made its last change on 8 March 2020 and has stayed seven hours behind Universal Time since. A few communities have always gone their own way: parts of the Peace River district and the East Kootenay in British Columbia, and Southampton Island in Nunavut. Canada also has a claim on the history: Port Arthur, Ontario, now part of Thunder Bay, put its clocks forward on 1 July 1908, eight years before any country did.

Born in Canada? Check the Province and the Year

For a birth chart, a Canadian birth time needs three facts: the place, the date and the rule that applied there then, and the rule has changed often. Before 2007 the dates ran from the first Sunday in April to the last Sunday in October. During the Second World War the whole country was on daylight time continuously from February 1942 to September 1945. Saskatchewan towns chose individually until the 1966 Time Act. And from 2026 a winter birth in Vancouver, Calgary or Winnipeg is an hour different from what the old rule would give. Get the hour wrong and the Ascendant lands some fifteen degrees away, often in the next sign. The calculator on this site looks up the province's rule for the exact date, the 2026 break included.
