In 2007, the United States and Canada implemented changes to “spring forward” earlier and “fall back” later. They extended Daylight Saving Time to last 238 days, giving Americans and Canadians more daylight hours in the evening during much of the year. Daylight Saving Time in Europe is 21 or 28 days shorter than in the United States and Canada, depending on the calendar year.
In Europe, DST will end a week before Canada, on October 26, 2025.
Clocks will change in almost all areas in Canada, except:
Several Canadian provinces, including British Columbia (BC), Ontario, and Alberta, have pushed to end Daylight Saving Time (DST), but progress remains slow.
BC introduced a legislation amendment in 2019 to stay on permanent DST but is waiting for Washington, Oregon, and California to take action to maintain alignment.
Ontario passed the Time Amendment Act in 2020 to remain on DST year-round. But they are unlikely to implement it until New York State and Québec formalize their positions, again to ensure alignment on trade and other economic factors.
In 2021, Alberta held a referendum on abolishing the biannual time change. The public vote was a narrow result in favor of retaining the system of adjusting clocks twice a year.
Canada implemented DST as far back as 1908, making the small towns of Port Arthur and Fort William (later Thunder Bay) the first documented cases of Daylight Saving Time being adopted in the world.
Also starting DST on March 9, 2025, are Cuba, Bermuda, The Bahamas, Saint Pierre and Miquelon, and Thule Air Base in Greenland.
