Why sunset time shifts in Ontario

Sunset drifts through the year with Earth’s ~23.4° axial tilt — see the full daylight explainer.

In Ontario, the longest day carries about 14h 25m of daylight and the shortest just 9h 53m — a swing of roughly 4h 33m between the June and December solstices. The farther a place sits from the equator, the wider that gap; the pace also isn’t steady, moving fastest near the equinoxes and barely at all near the solstices. Every figure here is computed from the sun’s position for Ontario’s exact coordinates, in local time.
