Toronto is about to “spring forward.”

At 2 a.m. on March 8, clocks across much of Canada — including Toronto — will move one hour ahead as daylight saving time begins. The seasonal shift is designed to make better use of daylight during the warmer months by pushing sunset later into the evening.

The change will be noticeable right away. On March 7, sunset in Toronto is expected at 6:13 p.m., but after the time change it jumps to 7:15 p.m. on March 8 and 7:16 p.m. on March 9, giving residents longer evenings of sunlight as spring approaches.

Daylight saving time in Ontario will remain in effect until November 1, when clocks will “fall back” one hour.

Not every region in Canada observes the time change. Saskatchewan stays on the same time year-round, while parts of Nunavut, eastern Quebec, and some northwestern Ontario communities also skip the seasonal shift.

The practice dates back to 1908, when the first Canadian daylight saving experiment was introduced in the cities of Port Arthur and Fort William — now part of Thunder Bay.

So before heading to bed Saturday night, make sure your clocks are set ahead — even if it means losing an hour of sleep.
