Canadian time zone and daylight saving time
There are six time zones in Canada: EST, CST, MST, PST, AST and NST.
There are six time zones in Canada, similar to the US, including Eastern Time (EST), Central Time (CST), Mountain Time (MST), and Pacific Time (PST). The other two are Atlantic Standard Time (AST) and Newfoundland Standard Time (NST).
Since 2007, Canada has followed North American Daylight Saving Time standards. Daylight saving time begins on the second Sunday of March each year. At this time, people adjust the clock one hour ahead; summer time ends on the first Sunday of November every year, and the people need to adjust the clock one hour later.
According to daylight saving time regulations, the start and end times of daylight saving time are different each year. Take 2019 as an example. Canada's summer time in 2019 begins on March 10 and ends on November 3.
It should be noted that some parts of Canada do not implement daylight saving time, including: Québec in the east of 63 degrees west longitude, most parts of Saskatchewan, and Southampton Island.
There is also a related news that just happened: In November 2019, BC legislation will begin to use daylight saving time permanently in 2020.
