40+ - most Canadians stop eating food and hope for a quick death
35 - you might just be able to live with this if you do nothing at all
28 - right about the place where comfort gives way to a general sense of warmth, something that makes any Canadian uncomfortable
23 - room temperature, and why “room temperature IQ” is an insult only Americans could have come up with because their scale was made by a madman
15 - If it’s Autumn you are wearing a light jacket, if it’s Spring you are sweating
5 - sweater time
0 to -10 - that stereotypical TV winter experience, where everyone is skating and sipping hot chocolate? Yeah that’s like half the year here. You better like hot chocolate.
-15 - We enjoy the fresh air, others will probably find it painful to breathe directly; put on a scarf! Do not brush your teeth immediately before going outside unless you want to experience mint-flavoured pain.

-40 - turns out you can’t form snowballs in hell because the snow is too crispy
