Starting at 2 a.m. Sunday, clocks roll back one hour in most of Canada as Daylight Saving Time comes to an end for this year.
Daylight Saving Time, which begins in March every year, is a relatively recent invention: northern Ontario’s Port Arthur was the first town in Canada to start changing its clocks twice a year in 1908.
What you should do:
Clocks go back one hour starting at 2 a.m. Sunday, Nov. 4. When you get up Sunday morning, make sure to change your clocks — and especially your alarms.
Places that don’t have Daylight Saving Time:
Of course, don’t change your clocks if you’re in one of the various parts of Canada that doesn’t observe Daylight Saving Time, which include:
- Most of the province of Saskatchewan
- Peace River Regional District, B.C.
- Fort Nelson, B.C.
- Creston, B.C.
- Pickle Lake, Ont.
- New Osnaburgh, Ont.
- Atikokan, Ont.
- Quebec’s north shore
What the time change might do to you:
An extra hour of sleep sounds great, right? Unfortunately, like all time changes, it’s likely to have an impact on you.
A Global News analysis of 10 years of car accident data found that nine more pedestrians, on average, are hurt or killed in Toronto during the week following the time change. Various research studies in the U.S. suggest that this is linked to the evening rush hour suddenly going dark.
Getting an extra hour of sleep could also trigger headaches in people who are already prone to them, according to the Canadian Headache Society. The time transition has also been linked to a slight increase in diagnoses of depression and the rate of strokes.
Slowly adjusting your bedtime over a few days, rather than all at once, can help to mitigate the negative effects of a time change, according to Stuart Fogel, an assistant professor of psychology at the University of Ottawa.
