Most of the getaways above sit on big water — Lake Huron, Georgian Bay, Lake Erie, Lake Ontario or Lake Superior — or in lake-dense highland country. Large lakes generate onshore breezes and sit away from the boreal fire zones, so during many smoke events they stay a band cleaner than inland cities. That's not a guarantee: smoke plumes move, which is why we re-rank this list against live PM2.5 and AQHI data every hour rather than publishing a fixed list. If everything within three hours of St. Catharines is smoky, the rankings will say so — sometimes the honest answer is to stay inside with a filter running.
