Daylight saving time

Daylight saving time is observed in most provinces, and has since the late 1960s 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 Canadian provinces followed suit to mimic the change.

The latest United States change (Energy Policy Act of 2005), adding parts of March and November.
