Correction: Ottawa, Ontario IS in the Northern Hemisphere (45.4°N). The original answer was factually wrong.
Ottawa is at ~45°N—well north of the equator. The summer solstice (June 20–22) is the longest day of the year in the Northern Hemisphere. All locations north of the equator experience sunrise that day (except possibly within the Arctic Circle where midnight sun means no sunset/sunrise). Ottawa has a normal sunrise/sunset cycle.
