York Region, located in southcentral Ontario, Canada, assigned approximately 50 regional roads, each with a number ranging from 1 to 99. All expenses for York Regional Roads (i.e: maintenance, traffic lights, and snow clearing) are funded by the York Region government. Several new roads were assumed by the region include King–Vaughan Town Line and Kirby Sideroad. Most north-south roads originating in Toronto retains the proper names from south of Steeles Avenue. Roads on Georgina Island are maintained by Chippewas of Georgina Island First Nation despite the island being within York Region. Roads are generally paved with some gravel roads in less populated areas. Before the 20th Century most cleared roads were dirt roads.

Types of roads

King's Highways

There are 161 km of provincially maintained highways, termed "provincial highways" or "King's Highways" As in the rest of Ontario, the provincially maintained highways in York Region are designated with a shield-shaped sign topped with a crown. The highway number is in the centre, with the name ONTARIO below. These signs are known as shields. Provincially maintained highways generally have greater construction standards than municipally or locally maintained roads. Although they are usually one lane in either direction, several short sections with two lanes in one direction as a passing lane exist along the highways. York Region is also home to three 400-series highways, which are controlled-access freeways.

Toll highway

York Region is home to a privately-maintained (but provincially-owned) toll freeway, the 407 ETR. The freeway crosses the Region east-west near the southern border. Toll rates vary depending on the section, time of day, and mileage driven.

Regional Roads

York Regional Roads are signed with a flowerpot-shaped sign, as are most regional and county roads in Ontario. The road number appears in the centre of the sign, with the word REGION above and the word YORK below. Like King's Highways, these signs are known as shields. As par standard practice in regional municipalities, they run through and are signed in urban areas in addition to rural areas.
