There are a number of public transportation operators within the Greater Toronto Area, providing services within their jurisdictions. While these operators are largely independent, provisions are being made to integrate them under Metrolinx, which manages transportation planning including public transport in both the GTA and Hamilton. GO Transit, which recently merged with Metrolinx, is the Ontario's only intra-regional public transit service, linking the communities in the GTA and the city of Hamilton. Implementation of a 'Presto card' by Metrolinx has created a common means for all fare payments and allow for seamless connection between these and other transit operators.
Public transit operators in the GTA include Brampton Transit, Burlington Transit, Durham Region Transit, GO Transit, Milton Transit, MiWay (serving Mississauga), Oakville Transit, Toronto Transit Commission (TTC), and York Region Transit.
The GTA also has the largest and busiest freeway network in Canada, consisting of the King's Highways and supplemented by municipal expressways. One of the most principal highways in the GTA, Highway 401 is also longest in Ontario and is also one of the busiest highways in the world. Notably, a segment of the highway passing through the GTA holds the distinction of being the North America's busiest highway. The GTA is laced with a number of limited-access highways, including the 400-series highways. These include:
Highway 400 – York Region, Toronto
Highway 401 – Durham Region, Toronto, Peel Region, Halton Region
Highway 403 – Peel Region, Halton Region
Highway 404 – York Region, Toronto
407 ETR – Durham Region, Peel Region, York Region, Halton Region
Highway 409 – Toronto, Peel Region
Highway 410 – Peel Region
Highway 427 – York Region, Toronto, Peel Region
Queen Elizabeth Way – Peel Region, Halton Region, Toronto
Gardiner Expressway – Toronto
Don Valley Parkway – Toronto
William R. Allen Road – Toronto
The Toronto Pearson International Airport in Mississauga serves as the primary airport for the GTA.
The main airport serving the GTA is Toronto Pearson International Airport in Mississauga, which is Canada's largest and busiest airport. It processed over 33 million passengers in 2011 and nearly 35 million passengers in 2012. Toronto Pearson International Airport is operated by the Greater Toronto Airports Authority (GTAA), and could potentially be asked to help observe in the operations of the other airports in the area, but has yet to be asked to do so. John C. Munro Hamilton International Airport in nearby Hamilton also handles international flights handles some discount flights and charters and acts as an alternate to Pearson. Billy Bishop Toronto City Airport on Toronto Island is used for civil aviation, air ambulance traffic and regional scheduled airlines. YTO is a multiple airport code that works for Pearson, City Centre, and Buttonville Municipal Airport (located in Markham). There are also a number of smaller airports which are scattered throughout the GTA.
The Greater Toronto Airport Authority has also placed a tentative proposal to develop a new airport in Pickering (which also spills over into Markham and Uxbridge). As the GTAA predicts that Toronto Pearson would be unable to indefinitely be the sole provider for the bulk of Toronto's commercial air traffic in the next 20 years, they believe that a new airport in Pickering would address the need for a regional/reliever airport east of Toronto Pearson, as well as complement the airport in Hamilton, Ontario. The GTAA also stated that the new airport would create more opportunities for economic development in the eastern region of the Greater Toronto Area.
Communication

The Greater Toronto Area is served by seven distinct telephone area codes. Before 1993, the GTA used the 416 area code. In a 1993 zone split, Metropolitan Toronto retained the 416 code, while the other municipalities of the Greater Toronto Area were assigned the new area code 905. This division by area code has become part of the local culture to the point where local media refer to something inside Toronto as "the 416" and outside of Toronto as "the 905". Though for the most part this was correct, it is not entirely true as some portions of Durham and York Regions use the 705 area code. Furthermore, there are areas, such as Hamilton, the Regional Municipality of Niagara and Port Hope that use the 905 area code, but are not part of the GTA. The unincorporated community of Acton (located in Halton Hills), is the only community in the GTA that is covered under the area codes 519 and 226, the area code which covers most of Southwestern Ontario.
To meet the increased demand for phone numbers, two overlay area codes were introduced in 2001. Area code 647 (supplementing the 416 area code) was introduced in March 2001 and area code 289 (supplementing the 905 area code) was introduced in July 2001. Some individuals within the 905 area code region may have to dial long distance to reach each other; although residents of Mississauga and Hamilton share the same area code (905), an individual from Toronto, for example, would have to dial "1" to reach Hamilton, but not to reach Mississauga. Ten-digit telephone dialling, including the area code for local calls, is required throughout the GTA. In March 2013, two additional area codes will be introduced to the GTA: area code 437 in Toronto, and area code 365 in the area currently served by 905 and 289.
