Time in Canada

{{Short description|none}}  {{Use dmy dates|date=November 2025}} {{original research|date=March 2026}} {{Time zones of Canada}} Canada is divided into five time zones: Mountain, Central, Eastern, Atlantic and Newfoundland time.{{efn|At any given time in Canada, either five or six UTC offsets are active in Canada: UTC−7, UTC−6, UTC−5, UTC−4, UTC−3:30 (standard time only), UTC−3 (DST only), and UTC−2:30 (DST only).}} Many areas of the country's provinces and territories operate on standard time from the first Sunday in November to the second Sunday in March and daylight saving time the rest of the year.<ref name="CFS">{{CFS}}</ref>

The divisions between time zones are based on proposals by Scottish Canadian railway engineer Sandford Fleming, who pioneered the use of the 24-hour clock, the world's time zone system, and a standard prime meridian.<ref>{{cite journal |last1=Creet |first1=Mario |title=Sandford Fleming and Universal Time |journal=Scientia Canadensis: Canadian Journal of the History of Science, Technology and Medicine |date=1990 |volume=14 |issue=1–2 |pages=66–89 |doi=10.7202/800302ar|doi-access=free }}</ref>

==Daylight saving time== {{main|Daylight saving time in Canada}} Four Canadian cities, by local ordinance, observed daylight saving time in 1916. Brandon, Manitoba, adopted it on 17 April. It was followed by Winnipeg on 23 April, Halifax on 30 April, and Hamilton, Ontario, on 4 June.<ref>Doris Chase Doane, ''Time Changes in Canada and Mexico'', 2nd edition, 1972.</ref> Port Arthur, Ontario, was the first place in the world to introduce it, on 1 July 1908.

Daylight saving time is observed in eight of ten provinces and two of three territories, with exceptions in several provinces and Nunavut. Most of the province of Saskatchewan, despite geographically being in the Mountain Time Zone, observes year-round CST. In 2020, the territory of Yukon abandoned seasonal time change and moved to permanently observing MST year-round.<ref name="Yukon">{{Cite web|url=https://yukon.ca/en/news/yukon-end-seasonal-time-change|last=Government of Yukon|title=Yukon to end seasonal time change|date=4 March 2020|access-date=23 September 2020}}</ref> Under the Constitution of Canada, laws related to timekeeping are a purely provincial matter. 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.

In 2019, the legislature of British Columbia began the process of eliminating the practice of observing daylight saving time in the province. On 31 October 2019, the government introduced Bill 40 in the legislature, which would define "Pacific Time" as "7 hours behind Coordinated Universal Time (UTC)".<ref>{{cite web |url=https://www.leg.bc.ca/content/data%20-%20ldp/pages/41st4th/1st_read/gov40-1.htm |title=Bill 40 – 2019: Interpretation Amendment Act, 2019 |publisher=Legislative Assembly of British Columbia |year=2019 |access-date=3 November 2019 |archive-url=https://web.archive.org/web/20191103234634/https://www.leg.bc.ca/content/data%2520-%2520ldp/pages/41st4th/1st_read/gov40-1.htm |archive-date=3 November 2019 |url-status=live}}</ref> In a press release, the provincial government stated an intention to maintain alignment of clock time with Washington, Oregon, California, and Yukon.<ref>{{cite press release |url=https://archive.news.gov.bc.ca/releases/news_releases_2017-2021/2019PREM0118-002084.pdf |title=Interpretation amendment act sets stage for year-round daylight time |date=31 October 2019 |access-date=3 November 2019 |publisher=British Columbia Office of the Premier / Ministry of Attorney General |archive-url=https://web.archive.org/web/20191103234636/https://archive.news.gov.bc.ca/releases/news_releases_2017-2021/2019PREM0118-002084.pdf |archive-date=3 November 2019 |url-status=live}}</ref> The move follows a consultation earlier in 2019, in which the province received over 223,000 responses, 93% of which said they would prefer year-round DST as compared to the status quo of changing the clocks twice a year.<ref>{{cite news |newspaper=Vancouver Sun |first=Cheryl |last=Chan |date=11 September 2019 |access-date=3 November 2019 |title=B.C. survey shows overwhelming support for permanent Daylight Saving Time |url=https://vancouversun.com/news/local-news/b-c-survey-shows-overwhelming-support-for-permanent-daylight-time |archive-url=https://web.archive.org/web/20191103234635/https://vancouversun.com/news/local-news/b-c-survey-shows-overwhelming-support-for-permanent-daylight-time |archive-date=3 November 2019 |url-status=live}}</ref><ref>{{cite web |url=https://engage.gov.bc.ca/app/uploads/sites/502/2019/09/Daylight-Saving-Time-Final-Report.pdf |title=Daylight Saving Time Public Consultation: Final Report |year=2019 |access-date=3 November 2019 |archive-url=https://web.archive.org/web/20190911012641/https://engage.gov.bc.ca/app/uploads/sites/502/2019/09/Daylight-Saving-Time-Final-Report.pdf |archive-date=11 September 2019 |url-status=dead}}</ref><ref>{{cite news |website=CBC News |url=https://www.cbc.ca/news/canada/british-columbia/daylight-savings-poll-engagement-1.5200828 |title=B.C.'s daylight saving survey gets more public engagement than marijuana regulation |date=5 July 2019 |access-date=3 November 2019 |archive-url=https://web.archive.org/web/20190707082907/https://www.cbc.ca/news/canada/british-columbia/daylight-savings-poll-engagement-1.5200828 |archive-date=7 July 2019 |url-status=live}}</ref> The premier of British Columbia discussed the issue with Yukon premier Sandy Silver, who said in October that he needs more consultation with Yukon stakeholders, and with Alberta and Alaska.<ref>{{cite news |url=https://www.whitehorsestar.com/News/b-c-premier-meets-with-silver-grand-chief |title=B.C. premier meets with Silver, grand chief |first=Gabrielle |last=Plonka |date=1 October 2019 |access-date=3 November 2019 |newspaper=Whitehorse Daily Star |archive-url=https://web.archive.org/web/20191102233348/https://www.whitehorsestar.com/News/b-c-premier-meets-with-silver-grand-chief |archive-date=2 November 2019 |url-status=live}}</ref> On 2 March 2026, Premier David Eby announced that following these consultations, the province will permanently adopt daylight time on 8 March 2026; however, some eastern parts of the province that use Mountain Time will not be affected by the change.<ref>{{cite news |title=B.C. to end time changes, adopt year-round daylight time |url=https://www.cbc.ca/news/canada/british-columbia/b-c-adopting-year-round-daylight-time-9.7111657 |work=CBC News |date=2 March 2026}}</ref>
