[edit] Daylight saving time

Daylight saving time is observed in all provinces except Saskatchewan. Under the Canadian Constitution, laws related to timekeeping are a purely provincial matter whereas in the United States the Congress is able to enact laws related to timekeeping at the national level. In practice, since the late 1960s DST across Canada 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 starting in 2007, was adopted by the various provinces and territories on the following dates:

• Ontario, 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
• Newfoundland - November 20, 2006, but officially announced on January 18, 2007
• Nunavut - February 19, 2007^[1]
• Saskatchewan - no official action taken, as most of the province does not change their clocks back in winter, but the small parts that have historically observed DST near Alberta and Manitoba are presumed to be authorized to have the start and end dates the same as Alberta and Manitoba.^{[citation needed]}
