Daylight Saving Time Ends: Prepare for Sleep Disruptions and Health Impacts

As of November 1, 2025, Canadians will soon experience the biannual ritual of Daylight Saving Time coming to an end. On Sunday, November 2nd, clocks will fall back by 1 hour, with sunrise and sunset occurring about an hour earlier than the previous day.

While most digital devices will automatically adjust, analog clocks and watches will need to be manually updated. This time change, which occurs twice a year, has long been a subject of debate due to its potential impact on people's health and wellbeing.

Studies show the shift in daylight patterns can disrupt the body's natural circadian rhythms, leading to sleep disturbances, increased risk of accidents, and even a rise in suicides in the days following the time change. Those with seasonal affective disorder or irregular sleep schedules may struggle the most to adapt.

In 2020, the Ontario government voted to end the practice of biannual clock changes and make Daylight Saving Time the year-round standard. However, this change has not yet been implemented, as it requires coordination with neighboring regions like New York and Quebec, which have not yet followed suit.

For now, Canadians will continue to experience the biannual time shift, and experts recommend adjusting sleep schedules gradually in the days leading up to the change to help ease the transition and minimize potential health impacts.
