The arterial road network in York Region is a grid, with most roads running north–south or east–west. This was done under the leadership of British surveyor Augustus Jones during the 1790s. York Region assigned approximately 50 roads as
York Regional Roads, meaning that maintenance of these roads is done by York Region. They are signposted with numbers. The major highways in the Region are: •
Highway 7 (east-west) •
Highway 9 (east-west) •
Highway 48 (north-south) •
Highway 400 (north-south) •
Highway 404 (north-south) •
Highway 407 (east-west) •
Highway 427 (north-south) Former highways include: •
Highway 11 (north-south) •
Highway 27 (north-south) •
Highway 47 (east-west) •
Highway 49 (east-west) •
Highway 50 (north-south) • Note: Highway 27 and Highway 50 are still referred to as such on municipal road signs, but are no longer provincial highways.
Air transportation Most air travel is served by
Toronto Pearson International Airport, which is outside of York Region and is Canada's largest airport.
Markham Airport is a private aerodrome in Markham. There are also a few small airports with unpaved runways serving the region: Hare Field in Holland Landing (East Gwillimbury), Belhaven Airport in Georgina, and
Stouffville Aerodrome north of Stouffville.
Buttonville Municipal Airport was a larger regional airport in Markham that was used for general aviation and business aircraft. It closed in November 2023.
Public transportation at Yonge & Highway 7 subway platform York Region is served by: •
York Region Transit (YRT), which includes the
Viva bus rapid transit network, is the Region's local transit service •
GO Transit, which provides commuter bus and rail service •
Toronto Transit Commission (TTC), which has several bus routes which cross York's southern border, and which provide service along many north–south arterial streets in Vaughan, Richmond Hill and Markham. The western arm of the TTC's
Line 1 Yonge-University extends into Vaughan to serve
Vaughan Metropolitan Centre, and a future extension of the Yonge Street (eastern) portion of the line will serve the boundary areas of Vaughan, Richmond Hill, and Markham by the mid-2030's. Until 2001, the towns of York Region operated separate public transit services, which did not connect very well with each other. YRT was created by the Regional Government to combine five of these services: •
Vaughan Transit •
Markham Transit •
Richmond Hill Transit •
Aurora Transit - merged in 1999 with
Newmarket Transit •
Newmarket Transit Since 2001, bus routes have been extensively enhanced in the five communities which had pre-existing services, but YRT's services to East Gwillimbury is limited to two routes, and service to King, Georgina and Whitchurch-Stouffville are even more limited due to the relatively small populations in each of those towns. ==Water==
