About the time in Ottawa
The zone identifier America/Toronto is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/Toronto keeps pointing at Toronto time whatever the date, which is why every timestamp on this page is built from it.
Ottawa runs on America/Toronto, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Sunrise today lands at 06:12 and sunset at 07:59 local time, giving 13h 48m of daylight. Those figures come from the city's own coordinates (45.42, -75.70) rather than a country-wide average, so they match what you would actually see from a window in Ottawa.
