On Sunday, Canadians across most provinces will lose an hour of sleep as Daylight Saving Time (DST) kicks in. This annual tradition of “springing forward” continues to spark conversations about its benefits and drawbacks. Most clocks will advance an hour at 2:00 a.m. local time, shifting directly to 3:00 a.m., bringing brighter evenings and darker mornings.
Why Does Canada Observe Daylight Saving Time?
Daylight Saving Time was implemented to better use daylight during the longer summer days. Adjusting the clocks allows evening daylight to stretch further, benefiting various activities after work or school. It was initially adopted during World War I to conserve energy, but arguments about its benefits remain ongoing.
In Canada, most regions participate in this biannual clock change. However, some areas—including the Yukon and most of Saskatchewan—stick to standard time year-round. Certain British Columbia and Ontario communities, like Chetwynd and Atikokan, also bypass the time change entirely.
When and Where Does DST Begin?
This year, DST officially begins on Sunday, March 9, 2025, at 2:00 a.m. Clocks in most provinces will be shifted forward by an hour. This change means sunsets will happen later in the evening, making activities like evening walks or patio dinners more enjoyable.
According to Immigration News Canada, notable sunset times on March 9 include:
- Vancouver: 7:08 p.m.
- Toronto: 7:16 p.m.
- Calgary: 7:31 p.m.
- Halifax: 7:12 p.m.
These extended daylight hours often lead to increased outdoor activity, boosting local economies and improving overall well-being.
DST in Canadian History
Canada first adopted Daylight Saving Time in the early 20th century as a wartime measure to save energy. Over time, it became commonplace, with standardization occurring in the mid-20th century. Despite these efforts, the practice has faced criticism for disrupting sleep schedules and providing limited evidence of energy savings.
Various studies suggest the clock changes can negatively affect human health. The abrupt shift in time has been linked to increased risks of heart attacks, strokes, and even traffic accidents in the days following the change.
Regions That Don’t Observe Daylight Saving Time
Not all parts of Canada participate in Daylight Savings Time. For instance, Saskatchewan has maintained standard time for decades, except for areas like Lloydminster, which observes Alberta’s DST schedule. Additionally, Yukon now follows permanent daylight time, eliminating the need to adjust clocks twice a year.
Other regions, including parts of British Columbia like Fort St. John, Creston, and Dawson Creek, also bypass this practice. These areas argue that sticking to one consistent time better serves the community.
The Debate Around Daylight Saving Time
Though many Canadians follow the twice-a-year clock adjustment, the debate remains heated. Proponents suggest Daylight Savings Time extends evening sunlight, increasing the potential for outdoor activities. This could benefit mental health, boost energy levels, and reduce electricity usage during peak hours.
Critics, however, argue that disrupting circadian rhythms can have serious health implications. Sleep experts often side against DST, citing the risks of shifting internal clocks. Some jurisdictions, including large portions of Europe, have explored eliminating the practice.
Proposals in the United States, like the “Sunshine Protection Act,” have sought to make DST permanent nationwide. While this bill has yet to pass, it mirrors discussions across Canada, questioning whether the tradition still makes sense in modern society.
Tips for Managing the Time Change
Switching clocks forward can be a challenge, but there are ways to ease the transition:
- Gradual Sleep Adjustment: In the days before DST, try going to bed 15 minutes earlier each night.
- Focus on Morning Light: Natural sunlight can help adjust your internal clock. After the time change, spend some time outdoors in the morning.
- Limit Evening Screen Time: Reducing late-night screen use may improve sleep quality.
- Prepare Ahead: Change manual clocks the night before to avoid confusion in the morning.
Being proactive can help minimize the grogginess that often accompanies the clock change.
What Comes Next?
DST in Canada will continue until Sunday, November 2, 2025, when clocks “fall back” by an hour. Until then, Canadians can enjoy extended daylight hours for evening activities and events. While the time change isn’t universally loved, it marks the unofficial start of spring—a hopeful signal for warmer days ahead.

Daylight Saving Time is more than just a seasonal inconvenience; it’s a longstanding tradition that echoes historical necessity and modern debate. So, as Canadians prepare to lose an hour this weekend, the larger conversation about its future continues. Whether DST remains or fades into history, one thing is certain—this ritual unites the country, one clock at a time.
