Getting around in the city, and outlying areas, is simply a matter of preference. The Toronto Transit Commission (TTC) operates subways, buses and streetcars along the main arteries of Toronto giving commuters a variety of options. For those who want a little exercise with their commute, BIXI Toronto is a year-round public bike service that launched in 2011. Eighty bike stations and 1,000 bikes offer an additional and accessible mode of getting around the city. Connecting the Greater Toronto Area (GTA) with the downtown, GO Transit operates daily train and bus services and for those who would rather drive, the 401 highway, the Gardiner Expressway and the Don Valley Parkway all offer routes in and out of the city.
