More Canadian Provinces Move Away From Changing Clocks: What It Means for Your Health

Published 2026-10-30

Many Canadians will change their clocks again this fall. Most of Ontario, Quebec and the Atlantic provinces will turn their clocks back by one hour on November 1 to mark the end of daylight saving time. However, the change is part of a larger debate across the country, because more provinces are now considering or deciding to stop changing their clocks twice a year.

Supporters of ending the time change often say that it would make daily life simpler. People would no longer need to remember to adjust their clocks, devices and schedules in the spring and fall. Some people also say that it would give families and businesses more stable routines. Lawmakers in several provinces have discussed the idea, but the details of each plan can be different, and not every region has made the same choice.

The time change also raises questions about health. Many sleep experts say that moving the clock forward or backward can disrupt the body's internal clock, which is known as the circadian rhythm. This disruption can affect sleep quality, mood and daily energy for some people, especially in the days after the change. Because of this, health professionals often encourage Canadians to keep regular sleep habits, get natural light during the day and prepare for the time change in advance.

For now, residents in most of Ontario, Quebec and the Atlantic provinces should expect to change their clocks on November 1. Readers who want to know the rules in their own province should check official government sources, since the timing and future plans can vary from one region to another.
