As a Canadian myself, it really depends. Most of us only understand farenheit in certain contexts. Some of us can understand it for weather but I think that’s mostly older generations. I use farenheit for oven and pool temperature only. In every other context, it is meaningless to me.
Oh I know! It’s so weird. Ovens are probably because we get ours from the US, but why we do pool temperature in farenheit is a mystery to me.
