FORT ST. JOHN -- Millions of Canadians will notice their clocks turn back by one hour on Nov. 3, marking the end of daylight saving time for this year.
Most provinces and territories observe the shift, which occurs yearly on the first Sunday of November, with the exception of Northeast BC, Yukon, most of Saskatchewan, and parts of Nunavut and Quebec, which follow standard time year-round.
Dawn will come earlier in the morning, and darkness will loom sooner in the afternoon when standard time returns.
Canadians have, perhaps begrudgingly, participated in sunshine-oriented time changes since 1918.
The federal government introduced daylight saving time to increase production during the First World War, shifting an hour of sunlight from before breakfast to after dinner.
The federally-regulated time change ended with the First World War but resumed during the second, when Canada returned to a year-round daylight saving time.
The Canadian Sleep Society and the American Academy of Sleep Medicine have called for an end to daylight saving time.
In March, nearly 90,000 people signed a petition to end daylight saving time permanently in Canada.
