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.
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.[3]
Provincially maintained highways generally have greater construction standards than municipally or locally maintained roads.[4] 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.[3] As par standard practice in regional municipalities, they run through and are signed in urban areas in addition to rural areas.
King's Highways
The following is a list of provincially maintained highways in York Region. Communities are ordered by where the route encounters them (either from south to north or from west to east).
Richmond Hill, Markham, Aurora, Newmarket, Whitchurch-Stouffville, East Gwillimbury, Georgina
Highway 404 forms the eastern/western borders of part of Richmond Hill/Markham, Richmond Hill/Whitchurch-Stouffville, Aurora/Whitchurch-Stouffville, Newmarket/Whitchurch-Stouffville, and part of Newmarket/East Gwillimbury.
York–Durham Regional Road 30 (York–Durham Line), York Regional Road 32 (Ravenshoe Road), and Durham Region Road 23 (Lake Ridge Road) marks the York Region/Durham Region boundary
Formerly Highway 11. This road is the central divider of York Region (and Toronto, from where it continues). Very busy road (especially in Richmond Hill, Markham, and Vaughan). Yonge Street turns off York Road 1 south of Holland Landing and is signed York Road 51, while York Road 1 continues northwest to Bradford in Simcoe County. The Viva Blue BRT line serves Yonge Street.
Continues from Toronto. Before naming it was the 6th Line. Former sections of Kennedy before the present alignment include Old Kennedy Road, Fresno Circuit, and Main Street Unionville. Section bypassing Main Street Unionville was briefly named Unionville By-pass. York Regional Road status was interrupted between Davis Drive (continues briefly north to dead end) and Herald Road.[8] The interruption due to the existence of the Bendor and Grave Tract (York Regional Forest), created by re-forestation of developed land acquired by the province beginning in 1924.[9] Pheasant Run Golf Course's eastern end overlaps roadway. Its length is 68km (including Toronto parts of Kennedy road)
Continues from Toronto. Unsigned road continues north of Lloydtown-Auroa Road as to King Street then becomes 4th Concession Road ending just before the Holland River. Briefly across the Holland River is a short roadway called Keele Lane which end shortly at Tornado Road.
This route is a heavily travelled route, especially between Highway 400 and McCowan Road in Vaughan, Richmond Hill, and Markham. Most of Viva Purple and Viva Pink run on Highway 7. This route was part of Ontario Highway 7 before the 1997 downloadings. Portions in Markham was once called Wellington Street (short section exists south of 7 at Markham Road). Ontario Highway 7 continues east of Reesor Road.
Runs closely parallel to Highway 404. Formerly continued south into Toronto, with that section today incorporated into Highway 404, which was constructed on a separate alignment to the west through York Region. Connects with the highway south of Steeles with directional ramps. In 2010, the Woodbine Avenue By-Pass, was opened to preserve the community of Victoria Square in Markham as urbanization encroached; with the old alignment renamed Victoria Square Boulevard', though the bypass was redesignated as part of Woodbine Avenue proper in 2015.[10][11][12] Several former road stub exists with new names after various realignments: Union Street, in Gormley south of Stouffville Road.

Woodbine Avenue
Dalton Road
Georgina
Road is a suffixed route that runs east-west and defaults from Woodbine Avenue (RR #8), (with a turn required for traffic to continue along Woodbine). The road is also secretly designated as number #88.[7] Road name derived from early road surveying commonly used in the 19th and early 20th Centuries in Ontario.
Two of the roads pass through the centre of the village of Sutton. Richard Dalton was a landowner in nearby Virginia located near the Roman Catholic Church along the route from Highway 48 east of Sutton.[13]
Markham, Richmond Hill, Aurora, Newmarket, East Gwillimbury, Georgina
Continues from Toronto as Don Mills Road at Steeles Avenue and becomes Leslie Street north of John Street. Becomes The Queensway and passes through the centre of Keswick. This section is proposed to be renamed Main Street Keswick in the future. Leslie Street also continues from Toronto, but a short section north of Steeles is bypassed and/or broken (hence the portion following Don Mills Road) due to geography including (German Mills Park, Duncan Creek) and the German Mills residential area; section from Steeles to slightly north of Simonston Boulevard was once part of German Mills Road. The section of Leslie from Steeles to Waterloo Court is not part of the regional road. All sections of Leslie in Markham were once signed as 3rd Line.[14]

From Highway 27 to 8th Concession it follows the 19th sideroad. At the 8th, to avoid Pottageville swamp, it curves diagonally southwards until it reaches 7th Concession road. From the 7th to 5th Concession Road (Jane St), it runs roughly due east, between sideroads. At Jane St, it turns south until it reaches the former 18th sideroad. Turning east again, it follows the former 18th to Dufferin (3rd Concession). At Dufferin, it turns east, running on 17th sideroad.

Ninth Line Box Grove By-pass Donald Cousens Parkway
Aurora Road
Steeles Avenue
Markham, Whitchurch–Stouffville
Begins at a T-intersection at Steeles Avenue along the Toronto-York Region border, following Ninth Line north, before curving east to follow Donald Cousens Parkway. It then turns left at the Box Grove By-pass (Constructed in 2006-2007), which curves to rejoin Ninth Line just south of Highway 407. Ninth Line itself is bypassed through the former hamlet of Box Grove, ending at dead ends north of Rouge Bank Drive in the north and Sanders Drive near Donald Cousens Parkway in the south. North of the 407, Ninth Line divides Markham Village and Cornell. The jog north of Donald Cousens will be likely be eliminated by future road work by the region. The name Ninth Line is the original number assigned in the 1793-1794 surveying and was never named.[25] North of Aurora Road Ninth Line continues as local road to Vivian Creek Road and ends as a driveway into Mount Albert water tower. Sometimes referred to as 9th Concession Road.
14th Avenue / Alden Road / Centre Street
Highway 7
York–Durham Line
Markham, Vaughan
Has two sections, mostly following 14th Avenue through Markham and Centre Street in Vaughan. York Regional Road status is interrupted between Warden Avenue and Bathurst Street. West of Warden Avenue it briefly is signed as Alden Road and resumes by turning north opposite Hood Road, following a bypassed section of 14th Avenue, despite the remainder of Alden Road, a section of Esna Park Drive, and John Street creating a direct link between the through portion of 14th Avenue and Centre Street (albeit partially with only two lanes and a jog), which picks up the Regional Road 71 designation west of Bathurst. 14th Avenue itself ends at a dead end at Highway 404. Originally ran west of 404 to end at Bayview Avenue but this section was removed as a through road as residential areas developed, with the remaining section being parts of Green Lane, Bronte Road, Littlebrook Court, and 14th Lane. There are two sections of roadway re-routed: at Donald Cousens Parkway, a former section is now an abandoned gravel stub and a short section west of Markham Road is named Old 14th Avenue and leads into a retail plaza. Centre Street begins at Yonge Street and heads westward and bends north after Dufferin Street to end at Highway 7.
The road is interrupted twice. The first time is between Keele Street and Jane Street because of the CN rail yard. The second time is between Islington Avenue and Highway 27 because of the Humber River.
