In 1973, the last portions of Yukon switched to Pacific Time, leaving UTC−09:00 unused in Canada. * In 1988, Newfoundland observed "double daylight saving time" from April 3 until October 30, meaning that the time was set ahead by 2 hours. All of Newfoundland and southern Labrador, which observes UTC−03:30 as its standard time zone, observed UTC−01:30. This only happened in 1988 and the province now only adjusts its time by one hour for daylight saving time.

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)".
