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