Fri Feb 28 11:30:00 UTC 2025: ## Daylight Saving Time Returns to Canada: March 9th Marks the “Spring Forward”

**Toronto, ON** – Daylight Saving Time (DST) will begin in Canada on Sunday, March 9th, at 2 a.m. local time. Most Canadians will need to set their clocks forward one hour before bed on Saturday, March 8th, although smart devices will typically adjust automatically.

While DST provides longer evenings during spring and summer, its benefits are increasingly debated. Experts point to potential negative impacts on health, including disrupted sleep patterns and increased risk of cardiovascular issues. A recent study in the *Journal of Sleep Research* highlighted the negative effect on sleep regulation caused by the “spring forward” shift. Clinical psychologist Roger Godbout emphasizes the importance of morning light for mental and physical well-being, suggesting a permanent “fall back” time would be more beneficial.

Professor Michael Antle of the University of Calgary notes that the original purpose of DST—energy conservation during wartime—is less relevant today due to energy-efficient lighting. He highlights the disruption to circadian rhythms caused by the yearly time change. Further studies have linked DST to increased heart attack risk, as detailed in a 2019 *Journal of Clinical Medicine* report.

While most of the country observes DST, exceptions include Yukon, parts of Saskatchewan, Quebec, Ontario, and British Columbia, which remain on standard time year-round. The debate over the merits of DST continues, with some advocating for its abolishment altogether.
