Daylight Saving Time in Canada

As of 2007, the standard North American period for Daylight Saving Time is from the second Sunday of March to the first Sunday of November. Prior to 2007 from 1987 to 2006, Canadian provinces and territories practiced DST from the first Sunday of April to the last Sunday in October.

Daylight Saving Time begins and ends at 2 am local time (i.e., 2 am PST). For more information see the National Research Council Daylight Saving Time information.

In Canada, Time Zones and Daylight Saving Time usually have been regulated by provincial and territorial governments.

Clocks following the new North American standard for Daylight Saving Time are to be turned forward by one hour on the second Sunday in March and turned back on the first Sunday of November.

Smoke Alarms and Carbon Monoxide Detectors
An easy way to remember to change the batteries in your smoke alarms and carbon monoxide detectors is to change them when you change your clocks for Daylight Saving Time.

Every six months make it a habit to:

  • Replace batteries in smoke alarms and carbon monoxide detectors.
  • Prepare or restock an emergency supply kit for your home.
  • Prepare or restock an emergency supply kit for your vehicle.
  • Check home, yard and shed for hazardous materials and carefully discard any that are outdated, no longer used, or in poor condition.
