Ontario Weather

Ontario’s climate is considered continental. Due to Ontario’s size and diverse geography, temperatures may vary tremendously from region to region and even within the regions themselves.


Temperatures are given officially in degrees Celsius (C) with the Fahrenheit equivalent (F) often added. To convert Celsius to Fahrenheit, multiply the Celsius temperature by 9, divide that total by 5, and then add 32. The Weather Network provides current Ontario weather updates and local forecasts.
