Daylight saving Time in Canada - wikipedia Daylight saving Time in Canada Contents 1 History 2 By province or territory 2.1 British Columbia 2.2 Nunavut 2.3 Ontario 2.4 Quebec 2.5 Saskatchewan 3 See also 4 References 5 External links Daylight saving time ( DST ) is observed in all ten Canadian provinces and three territories. However, there are exceptions within several provinces and the territory of Nunavut, including most of Saskatchewan, which observes Central Standard Time year - round even though the province is in the Mountain Zone, effectively putting it on DST year - round. Under the Canadian Constitution, laws related to timekeeping are a purely provincial or territorial matter. In regions where daylight saving time is used, it commences on the second Sunday of March, and standard time restarts on the first Sunday in November. History Five Canadian cities, by local ordinance, used Daylight Saving Time before 1918 : Brandon, Manitoba and Winnipeg, Manitoba ( already in 1916 ) as well as Halifax, Nova Scotia, Hamilton, Ontario, and Montreal, Quebec. St. John 's, Newfoundland ( now Newfoundland and Labrador ), which did not become part of Canada until 1949, also used DST before 1918. In practice, since the late 1960s DST across Canada has been closely or completely synchronized with its observance in the United States to promote consistent economic and social interaction. When the United States extended DST in 1987 to the first Sunday in April, all DST - observing Canadian provinces followed suit to mimic the change. The latest United States change ( Energy Policy Act of 2005 ), adding parts of March and November starting in 2007, was adopted by the various provinces and territories on the following dates : Ontario, Manitoba - October 20, 2005 Quebec - December 5, 2005 Prince Edward Island - December 6, 2005 New Brunswick - December 23, 2005 Alberta - February 2, 2006 Northwest Territories - March 4, 2006 British Columbia - March 31, 2006 Nova Scotia - April 25, 2006 Yukon - July 14, 2006 Newfoundland and Labrador - November 20, 2006, but officially announced on January 18, 2007 Nunavut - February 19, 2007 Saskatchewan - no official action taken, as most of the province does not change their clocks back in winter, but the small parts that have historically observed ' DST ' near Alberta and Manitoba are presumed to be authorized to have the start and end dates the same as Alberta and Manitoba. By province or territory British Columbia Most of British Columbia ( BC ) is on Pacific Time and observes DST. However, there are two main exceptions : Part of the Peace River Regional District of BC ( including the communities of Chetwynd, Dawson Creek, Hudson 's Hope, Fort St. John, Taylor and Tumbler Ridge ) is on Mountain Time and does not observe DST. This means that the region 's clocks are the same as those in Calgary and Edmonton in the winter, they are the same as those in Vancouver in the summer. The residents of Fort Nelson have voted to also stay on year - round MST since 2015. The East Kootenay region of south - eastern BC ( including the communities of Cranbrook, Fernie, Golden and Invermere ) is on Mountain Time and observes DST. This means that the region is always on the same time as Calgary ; much of the region gets television by way of rebroadcasters of Calgary stations. One exception in this region is Creston, which observes MST year round. Clocks in Creston match those in Calgary in the winter, and Vancouver in the summer. Nunavut While the rest of Nunavut observes DST, Southampton Island including Coral Harbour remain on Eastern Standard Time throughout the year. The Kitikmeot Region including Cambridge Bay observes DST but is on Mountain Time. Ontario Most of Ontario uses DST. Pickle Lake, Atikokan and New Osnaburgh, three communities located within the Central Time Zone in northwestern Ontario, observe Eastern Standard Time all year long. Quebec Most of Quebec observes DST. However, the eastern reaches of Quebec 's North Shore, east of 63 ° west longitude, are in the Atlantic Time Zone, but do not observe DST ( see exception, below ). The effect is that in summer their clocks match those of the rest of the province, while in November, their clocks are rejoined by their Atlantic Standard Time neighbours. Although places east of 63 ° west are officially on Atlantic Time, local custom is to use Eastern Time as far east as the Natashquan River. Those communities observe DST, including all of Anticosti Island, which is bisected by the 63rd meridian. The Magdalen Islands observe Atlantic Time including DST. Saskatchewan Main article : Time in Saskatchewan Although the entire province is geographically within the MST ( UTC - 7 ) zone, the province is officially part of the Central time zone ( UTC - 6 ). As a result, while most of Saskatchewan does not change clocks spring and fall, it technically observes DST year round. This means that clocks in most of the province match clocks in Winnipeg during the winter and Calgary and Edmonton during the summer. This time zone designation was implemented in 1966, when the Saskatchewan Time Act was passed in order to standardize time province - wide. The charter of the city of Lloydminster, which is bisected by the Saskatchewan -- Alberta boundary, gives it a special exemption. Lloydminster and the immediately surrounding region in Saskatchewan observe Mountain Time year - round, with officially sanctioned seasonal daylight saving time ( which in the summer, puts it in sync with the rest of Saskatchewan ). This is to keep clocks on the Saskatchewan side in sync with those on the Alberta side ; Alberta mandates the use of daylight saving time province - wide. Along the Manitoba border, the small, remote Saskatchewan towns of Denare Beach and Creighton unofficially observe Central Daylight Time during the summer, thereby keeping the same time as larger neighbouring Manitoba communities.
