In the summer all of Canada’s provinces, except for part of Saskatchewan and a few other areas, shift to daylight saving time, meaning that the clock is put forward in the spring in order to extend daylight hours in the evening. Normal time is restored in the fall by putting clocks and watches back an hour.
Sandford Fleming never experienced this system, which was proposed by the federal government in 1918. Putting the clocks forward makes it possible to save energy by benefiting from natural lighting at the end of the day.
However, the federal regulation disappeared with the end of the war and from then on, municipalities decided by referendum every year whether or not they would join the daylight saving system.
Since 1987, provinces and territories have had the power to make decisions about time zones and daylight saving time.
