Turn down the heat. Turn up your sweater. Sweater Day is back! On February 9, we want Canadians to put on a sweater and lower their thermostats, to take action on climate change. Show your support by wearing the brightest one you own.

This year, we’ve enlisted a few helpers to get the word out (hint: What’s 80 years old, sweet, and always trying to get you into a sweater?)
