The cost of public transportation in Toronto varies based on the type of transit service you’re using. The Toronto Transit Commission (TTC), which includes buses, streetcars, and subways, typically charges a single-ride adult fare of $3.25 CAD (Canadian dollars) with discounts for tokens, Presto cards, monthly passes, and younger riders. However, fares can change over time, so I recommend checking the official TTC website for the latest information.
