I think younger people in Canada only know °F if their thermostat is set to it and they can’t or don’t bother to change. My stupid fridge is in Fahrenheit and that can’t be changed (even though the handbook shows the display in Celsius! A variation of the model is probably sold abroad).
I think Canada properly adopted Celsius, kilometres, litres and millilitres (at least here in Toronto), but all other metric units are the underdog. Even CBC, that is probably the only media outlet that tries to stick to metric will specify people’s height in feet and inches. Shameful.
