Tomorrow We Switch to Daylight Saving Time

On the night of March 8, 2026, most Canadians will move their clocks forward by one hour. Provinces and territories that observe Daylight Saving Time include Newfoundland and Labrador, Nova Scotia, Prince Edward Island, New Brunswick, Quebec, Ontario, Manitoba, Alberta, the Northwest Territories, and most of Nunavut. Yukon, most of Saskatchewan, and Southampton Island in Nunavut do not change their clocks. For British Columbia, however, tomorrow’s change will be the last seasonal time shift, as the province has decided to stop changing the clocks in the future.

For the human body, this shift is small but noticeable stress. The spring time change often disrupts sleep, reduces concentration, and increases fatigue. In the first few days it can also be associated with short-term health risks. On average, people adapt within a few days, although for some it may take up to a week or longer. Exposure to morning daylight helps the body adjust more quickly.

As for electricity savings, they are no longer as significant as they once were. Energy-efficient LED lighting has greatly reduced the share of lighting in household electricity use. As a result, the main argument for changing the clocks appears weaker today. In other words, we still move the clocks, but the actual energy savings are no longer as impressive.
