The number of days needed to visit Toronto depends on personal preferences and interests. However, a minimum of 3-4 days is recommended to explore the city's top attractions and neighborhoods, as well as to experience its food, culture, and outdoor activities.

The cheapest way to travel in Toronto is by using the TTC (Toronto Transit Commission) public transit system, which includes buses, streetcars, and subways. Single rides with the TTC are more affordable than other options like taxis or rideshares, making it a cost-effective choice for getting around the city.

Before visiting the CN Tower in Toronto, it's important to know that tickets can be purchased online to avoid long lines. Check the weather, as visibility affects the view. The EdgeWalk attraction requires advance booking and has certain age/height restrictions. Parking can be limited, so public transit is recommended. Cameras and tripods are allowed, but selfie sticks are not. The tower offers dining options.

In Toronto, there are several free activities you can do and enjoy. For example, exploring High Park’s nature trails, gardens, and zoo, or wandering through the Distillery History District that is famous for its art installations and boutiques.
