The Arctic air is back in Toronto, Peterborough, and other parts of Canada this winter; and outside temperatures are dipping to as low as the -30s. Hopefully, you have done all the necessary preparations to winterize your Toronto home. If not, make sure to take all the necessary precautions, as the chill is expected to last for a few months more.
First, check that your heating system is in very good condition, and have it professionally inspected to ensure that it continues working properly throughout the season. Toronto city officials recommend keeping indoor temperatures at 21 degrees C. It would also be good to install carbon monoxide detectors for added security.
