Time information on Canada - Ottawa

Only a minority of the world's population uses DST because Asia and Africa generally do not observe it.

William Willett independently proposed DST in 1907 and advocated it tirelessly.
Willett's 1907 proposal argued that DST increases opportunities for outdoor leisure activities during afternoon sunlight hours
The longer days nearer the summer solstice in high latitudes offer more room to shift daylight from morning to evening so that early morning daylight is not wasted.
General agreement about the day's layout confers so many advantages that a standard DST schedule usually outranks ad hoc efforts to get up earlier, even for people who personally dislike the DST schedule.
DST's potential to save energy comes primarily from its effects on residential lighting, which consumes about 3.5% of electricity in the U.S. and Canada.
Delaying the nominal time of sunset and sunrise reduces the use of artificial light in the evening and increases it in the morning
As Franklin's 1784 satire pointed out, lighting costs are reduced if the evening reduction outweighs the morning increase, as in high-latitude summer when most people wake up well after sunrise
An early goal of DST was to reduce evening usage of incandescent lighting, formerly a primary use of electricity.
Energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results
Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.
The U.S. of Transportation (DOT) concluded in 1975 that DST might reduce the country's electricity usage by 1% during March and April,
In 2000 when parts of Australia began DST in late winter, overall electricity consumption did not decrease, but the morning peak load and prices increased.
In Western Australia during summer 2006–07, DST increased electricity consumption during hotter days and decreased it during cooler days, with consumption rising 0.6% overall.
Although a 2007 study estimated that introducing DST to Japan would reduce household lighting energy consumption,
A 2007 study found that the earlier start to DST that year had little or no effect on electricity consumption in California.
A 2007 study estimated that winter daylight saving would prevent a 2% increase in average daily electricity consumption in Great Britain.
