in the world to introduce it, on July 1, 1908. Daylight saving time is currently observed in nine of ten provinces and two of three territories, but 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. 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 October 31, 2019, the government introduced Bill 40 in the legislature, which would define "Pacific Time" as "7 hours behind Coordinated Universal Time (UTC)". In a press release, the provincial government stated an intention to maintain alignment of clock time with Washington, Oregon, California, and Yukon. 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. 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. The latest United States change (Energy Policy Act of 2005) to daylight saving time, adding parts of March and November to when daylight saving time is observed, which began in 2007 was adopted by the various provinces and territories on the following dates: Ontario and 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. Year-round MST as of March 8, 2020. Newfoundland and Labrador – November 20, 2006, but officially announced on January 18, 2007 Nunavut – February 19, 2007 Saskatchewan – No official action was
