This is the weekend most Canadians will gain an hour of sleep as they switch from daylight saving time to standard time.
In most parts of the country, clocks should be turned back one hour by 2 a.m. Sunday.
The time change doesn't apply to Saskatchewan, which remains on central standard time year-round -- except for the city of Lloydminster which straddles the border with Alberta, and is on mountain time.
Other parts of Canada that keep to standard time include northeastern British Columbia, the East Kootenay region of southeastern B.C., three communities in northwestern Ontario, the eastern tip of Quebec and Southampton Island in Nunavut.
But there are rumblings across the continent that people are growing weary of moving their clocks ahead one hour in the spring -- losing an hour of sleep -- and then turning them back in the fall.
The Alberta government looked into scrapping daylight saving time before rejecting the idea last week, and there are similar proposals taking root in New England, where there are several anti-DST bills at various stages.
