Canadians are changing their clocks tonight as much of the country prepares to spring forward for daylight time.
The change happens for most of the country at 2 a.m. local time.
Yukon and most of Saskatchewan keep their clocks the same year-round.
Canadians can thank an avid Ontario golfer in Thunder Bay for introducing daylight time to the country.
In 1908 the towns of Port Arthur and Fort William – now Thunder Bay – brought in seasonal time-shifting for July and August.
