What winter is actually like in Oshawa
Oshawa sits directly on Lake Ontario, which keeps the lakeshore a degree or two warmer than the north end of the city and turns that difference into freezing rain rather than snow more often than people expect. The practical effect is potholes: the constant freeze-thaw along Simcoe Street and Ritson Road opens them up fast in February and March, and a hard hit into one is the single most common cause of the sidewall damage and knocked-out wheel balance we see here in early spring.
