I looked it up! We reached 109 degrees in Ontario in 1975. I don’t remember that, but, whatever. I obviously survived it, but I sure wouldn’t now without air!
Growing up here I recall many summers of 110+ with no air-conditioning. We had a fan and I remember my mother putting a cold towel in front of it. No air in cars just wing windows.
The year we moved back here from Calif. in July 1979 it was 115. Thankfully we had air conditioning then.
