What is cost of stamp to Toronto?

The cost of a stamp to send a letter to Toronto, Canada, typically depends on the weight and size of the letter, as well as the service used (e.g., standard mail, express). As of my last update, domestic postage rates in Canada start at around CAD 1.07 for standard letters. It's best to check with Canada Post or a current postal service provider for the most accurate and up-to-date pricing.
