Toronto is the largest city in Canada and one of the most popular destinations for American expats for a good reason. The lifestyle in Toronto is very similar to many large cities in the United States. There are some differences, though. Toronto has slightly colder winters than what you may be used to. On the plus side, you'll be able to enjoy free primary healthcare. Canadians use metric measures instead of miles, liters instead of gallons at gas stations, and Celsius instead of Fahrenheit.
