Stargazing in Toronto, Canada

Toronto's Bortle 8 urban glow is one of the brightest in Canada, but the Ontario countryside darkens within 90 minutes heading north. The Torrance Barrens Dark Sky Preserve (2 hours north) was one of Canada's first, offering Bortle 3 conditions on the Canadian Shield. Lake Ontario moderates temperatures but also generates lake-effect cloud in autumn. Winter high-pressure systems bring the clearest, coldest, and most transparent nights.
