How hot was it in Hamilton on Wednesday?
Hot enough to break the all-time temperature record for Sept. 5.
Environment Canada says the temperature at Hamilton’s John C. Munro International Airport reached a high of 31.4 C on Wednesday afternoon.
That beat the old record of 30 C set in 1971.
St. Catharines, Toronto, Kitchener and London also broke temperature records on Wednesday, the final day of a four-day heat wave in southern Ontario.
