Greater Toronto and Hamilton Area


The Greater Toronto and Hamilton Area is a contiguous urban region that is composed of some of the largest cities and metropolitan areas by population in the Canadian province of Ontario. The GTHA consists of the Greater Toronto Area and the city of Hamilton. The GTA is Canada’s most populous metropolitan area that includes the city of Toronto and the regional municipalities of Halton, Peel, York, and Durham. The GTHA forms the core of a larger urban agglomeration known as the Golden Horseshoe.
The GTA population is 6,417,516. Beginning in the late-2000s, the term "Greater Toronto and Hamilton Area" was introduced by a few public bodies to refer to the GTA and the city of Hamilton as a single entity. The population of the combined area is 6,954,433 as of 2016, and is projected to grow to 8.6 million by 2031. The main series of roadways that connects all the areas together includes highways 401, 427, 403, and the Queen Elizabeth Way. The GTHA region is served by regional transport agency, GO Transit.
