In Canada, daylight saving time (DST) is observed in nine of the country's ten provinces and two of its three territories—though with exceptions in parts of several provinces and Nunavut.[1]

Under the Canadian Constitution, laws related to timekeeping are a provincial and territorial matter.[2] Most of Saskatchewan, despite geographically being in the Mountain Time Zone, observes year-round Central Standard Time (CST). In 2020, Yukon abandoned seasonal time change and moved to permanently observe year-round Mountain Standard Time (MST).[3]

In the regions of Canada that use daylight saving time, it begins on the second Sunday of March at 2 a.m. and ends on the first Sunday in November at 2 a.m. As a result, daylight saving time lasts in Canada for a total of 34 weeks (238 days) every year, about 65 percent of the entire year.
