This has been the most sustained cold winter I have experienced in 30 years. -30C at night has been normal for a long time, with highs between -24C and (rarely) -9C. And we near Thunder Bay, are in the same latitude as Vancouver! I hate the Polar Vortex! So much for global warming. I suspect many people in our area, who have spent a fortune on heating bills, will be thinking of moving south.
