Ottawa is located at 45.42°N, 75.70°W. Its latitude determines how dramatically daylight hours change through the year.
The city uses the America/Toronto timezone (EDT). It observes Daylight Saving Time, so sunrise and sunset times shift by one hour in spring and autumn.
Solar noon — the moment the sun reaches its highest point in the sky — occurs when the sun crosses the local meridian. In Ottawa this falls around 13:01 in mid-summer and 11:52 in December, reflecting UTC offset and any DST adjustments.
