If you live in Southern Ontario, chances are you often hear the term GTA, or Greater Toronto Area. But what cities and towns are included in the GTA? If you're curious or just want to learn more, whether you live in Toronto or you're a visitor, below you will find an outline of the cities and towns in the GTA as well as a few highlights of what you can see and do in each area.

Besides all of the neighbourhoods in the amalgamated City of Toronto, when people refer to the Greater Toronto Area they are usually talking about an area which includes the regions of Halton, Peel, York and Durham. These regions often make great day trips from the city for their many attractions, which include everything from beaches and conservation areas, to art galleries, craft breweries and museums.

Living and Working in the GTA

It is not uncommon for GTA residents to live in one municipality and work in another, including people who commute both into and out of Toronto daily. In these cases, it's helpful to stay updated on Toronto traffic. But there are also ways to use public transit between the regions, such as GO Transit, and options to connect between the public transportation systems in the GTA using local transit systems.
