Dufferin Street

The southern end of Dufferin is the Dufferin Gates at the entrance to Exhibition Place, which holds the annual Canadian National Exhibition (CNE). The two Dufferin Street bridges connect the Exhibition Place with the rest of Dufferin Street to the north. The 1911 bridge span across the railway north of the CNE grounds was determined to be unsafe for vehicular traffic in 2013, and was closed to vehicles. The bridge was scheduled for replacement starting in 2016.[3] The City of Toronto plans to build a temporary bridge to restore vehicular traffic in advance of the replacement construction.[4]

North of the CNE grounds, the east side of Dufferin Street is dominated by industrial or transitional industrial to residential and commercial buildings of Liberty Village, with several old factories being converted to loft-style condominiums. The west side is mostly single-family homes with one apartment building south of King Street. The neighbourhood to the west is named Parkdale, which was developed mostly before 1900.

North of Queen Street West, Dufferin is primarily residential on both sides, with the large Dufferin Mall on the west side of Dufferin, south of Bloor Street. This was the former site of the Dufferin Park Racetrack. Across the street from the mall is the Dufferin Grove city park. From Queen Street north to College Street, the neighbourhood is known as Little Portugal. North of College, and west of Dufferin is the former village of Brockton and on the east is the Dufferin Grove neighbourhood, named after the park on the east side of Dufferin. Dufferin station is located at Dufferin and Bloor Street on Line 2 Bloor–Danforth of the Toronto subway system.

From Bloor Street to Davenport Road, Dufferin is lined with homes built from the 1920s to post-World War II. The Galleria Shopping Centre is located on the west side of Dufferin and on the south side of Dupont Street. The neighbourhood west of Dufferin in this area is known as Wallace Emerson, while on the east it is known as Dovercourt Park. North of Davenport, Dufferin ascends the former Lake Iroquois shoreline escarpment. North of the escarpment, the street continues to be residential on both sides north to Eglinton Avenue West. Between Rogers Road and Eglinton Avenue West, Dufferin crosses two steep ravines.

Dufferin Street is eight lanes wide in the vicinity of Highway 401.

North of Eglinton Avenue, it becomes a six-lane arterial road through industrial and low-density commercial lands of the former North York. The regional shopping centre of Yorkdale Shopping Centre is located at Dufferin and Highway 401. The sections from Eglinton into York Region was originally Vaughan Road.

North of Wilson Avenue, Dufferin is interrupted by Downsview Airport and Allen Road, the latter of which feeds Dufferin north of Kennard Avenue (formerly Wilson Heights Boulevard), north of Sheppard Avenue.

A broken section of Dufferin Street runs parallel with Allen Road, one block east, south of the continuation from Allen Rd., from Sheppard Ave. to Kennard Ave. This section is a residential street and ends in a cul-de-sac just south of Kennard. North of Wilson, Dufferin Street runs 210 metres (690 ft) to Katherine Street and continues on as Beffort Road/Hanover Road.

Dufferin Street continues north of Steeles Avenue into the city of Vaughan. The section north to Highway 7 and Langstaff Road is a six-lane arterial road, designated as York Regional Road 53. North of that, it narrows to four lanes, then narrows again two blocks north of Major Mackenzie Drive to two lanes. North of Lloydtown/Aurora Road (York Road 16) / 18th Sideroad (York Road 26), it is maintained by King Township and terminates just north of Graham Sideroad in the Holland Marsh, after jogging at Davis Drive (York Road 31), the former Highway 9.

The Dufferin Jog was recently removed at Queen Street, providing drivers with a direct continuation of Dufferin Street

The intersection of Dufferin Street and Queen Street West intersects with the main railway line from northwest of Toronto to downtown at Union Station. This intersection was the site of the Parkdale Train Station which was originally a level crossing. In the 1890s, an underpass (initially called "the subway") was built for Queen Street to accommodate growing east–west traffic; however, one was not built for Dufferin Street to connect it a block north of Queen. At the time, the area north of the railway line was heavily industrial and factories backed onto the tracks. North–south traffic was not expected nor planned for and the two sections of Dufferin were not connected.[5] As automobiles arrived in Toronto around 1903, and for the next 107 years, vehicles looking to travel along Dufferin detoured around the closed section to Peel (east–west) and Gladstone (north–south), which became de facto sections of Dufferin. The detour was known locally as the "Dufferin Jog".

The jog was eliminated in 2010 with the construction of a four-lane underpass beneath the railroad track, including public art and an amphitheatre-styled park with tiered gardens at the southwest corner of the underpass. This project was approved by city council in 2007, and work on extending the roadway began in July 2009.[6] The underpass was opened on November 18, 2010.[7] A further widening of the north side of the bridge was completed in 2016–2017 to support expanded GO Transit train service.[8]

The section of the east side of the bridge along Queen Street was built in 1897 as the Queen Street Subway.

There is also currently a jog from Wilson to Sheppard, caused by the Downsview airbase built in 1929, which when built, was a rural area. Wilson Heights Blvd was built rerouting the northern section to head east avoiding the airport, with a jog at the southern section. In 1982, the northern section was rerouted again into Allen road. Today the path to connect the 2 sections is to go east on Wilson Avenue, north on Transit road, north on Allen road, of which funnels into Dufferin, and vice-versa.
