The Hurontario-Main LRT is a planned light rail line in Peel Region, Ontario, Canada. This line will run along Hurontario Street, also called Main Street north of Steeles Avenue, within the cities of Mississauga and Brampton. Due to the involvement of two transit agencies in this project, it is currently unclear which agency will operate the line; however, it is likely that Metrolinx will own the line.
The Cities of Mississauga and Brampton have identified higher-order transit along Hurontario and Main Streets due to the chronic overcrowding situation in Mississauga's (and the 905 region's) busiest bus route, 19 Hurontario, which carries more than 25,000 passengers a day, combined with the massive-scale high-density development proposals along the corridor and the anticipated high growth in both cities. They have identified three options: light rail transit for the entire corridor, bus rapid transit for the entire corridor, or a combination of both (light rail south of Mississauga City Centre and bus rapid transit north of it). After three public information sessions, the residents of both cities agreed overwhelmingly in favour of light rail transit along the full length of the corridor.
The LRT line will cost around $1.6 billion.
The LRT line will run from the intersection of Port Street and Elizabeth Street for better access in the waterfront. The line will then turn left at St. Lawrence Drive. North of Lakeshore Road, St. Lawrence Drive becomes Hurontario Street. At Park Sreet, the LRT will directly connect to a relocated Port Credit GO Station. The line continues northward crossing Queen Elizabeth Way. At Dundas Street, it will connect to a proposed rapid transit line (either a BRT or an LRT). The LRT will indirectly connect to Cooksville GO Station using the LRT stop at John Street. The line continues northward until it splits into two branches between Burnhamthorpe Road and Rathburn Road:
- Downtown alignment: from Hurontario Street, the LRT will turn left at Burnhamthorpe Road, turn right at Duke of York Boulevard, then turn right at Rathburn Road, then turn left and meet up with the other branch at a location yet to be determined. This branch serves almost all of Mississauga City Centre using a walking distance of 500 metres (1,600 ft), including those who are transferring to the BRT and City Centre Transit Terminal.
- Mainline alignment: the route continues straight along Hurontario Street. This branch serves passengers working in the offices in the eastern part of the City Centre and those who want to bypass Downtown Mississauga and allow faster through travel along Hurontario Street.
From Rathburn Road, the LRT will bridge over Highway 403. At Highway 407, the LRT will connect to GO Transit's proposed Highway 407 Transitway. At Steeles Avenue, it connects to Shoppers World Terminal to connect with Züm Steeles BRT line. North of Steeles, Hurontario Street becomes Main Street. The line will then end at Downtown Brampton directly at Brampton GO Station.
As of the second Public Information Centre, the LRT will have a dedicated right-of-way throughout the entire corridor, except for a few sections at the segment north of Nanwood Drive, where the segregated right-of-way has been removed to allow left-turn or right-turn lanes. As a result, road space along most of the corridor will be reallocated from two car lanes to the LRT, leaving four lanes for automotive traffic. Some narrower sections of Hurontario/Main Street will be reduced to one car lane per direction. These sections include:
- Port Credit,
- Duke of York Boulevard,
- north of Nanwood Drive, and
- Downtown Brampton (if the transit mall proposal wouldn't be approved).
- Port Street, where two lanes at the south side will be taken away,
- Duke of York Boulevard, where two lanes at the east side will be taken away,
- Main Street within Downtown Brampton, where the two curbside lanes will be taken away (if the transit mall proposal wouldn't be approved), and
- Hurontario Street between Inglewood Drive and Lakeshore Road, where two lanes to the west side will be used for LRT, with a new bridge at Eaglewood Boulevard to compensate for the proposed removal of the intersection at Inglewood Drive.
- Rathburn Road, which will be widened at the south side, with two lanes taken away at the north side for the LRT.
The LRT line can have a few modifications along the route as it enters the later phases of the study:
- At Downtown Brampton, a transit mall is proposed between Queen Street and Nelson Street. This section of Main Street would be closed to traffic if this alternative is to be approved.
- Within Downtown Brampton, it is possible for the LRT to directly serve Brampton GO Station by tunnelling under the Georgetown line. However, during the early design phase, this alignment has been rejected since:
- running the LRT on two streets would prove to be costly during construction, especially with the proposed rail bridge underpass
- constructing the LRT on two streets would be disruptive to traffic, utilities and businesses, and
- the LRT would block access to the City Hall 
- There is also a proposed diversion to Peel Memorial Hospital, but ultimately rejected due to its floodplain location, significant distance away from Downtown Brampton and increased costs.
- The LRT line is designed to perform short turns within Mississauga City Centre from both Brampton and Port Credit in case of accidents, closures or high ridership loads.
- Within Mississauga City Centre, the LRT may cross Highway 403 in two ways:
- the mainline branch turns left at Square One Drive, then turns right to City Centre Drive, then meets with the downtown branch at Rathburn Road, then cross Highway 403 using a new bridge.
- the downtown branch meets with the mainline branch at Hurontario Street north of Rathburn Road, requiring the Hurontario Street bridge to be widened to accommodate the LRT.
- Mayor Susan Fennell of Brampton proposed to run the 502 Zum Main along the entire LRT route to Port Credit. Mayor Hazel McCallion of Mississauga rejected the alternative proposal, citing gridlock south of Mississauga City Centre as a reason.
The LRT is planned to run every 5 minutes during rush hours, and every 10 minutes for the rest of the week. Service hours on the LRT corridor is planned to be between 5:00 AM and 1:30 AM Mondays to Saturdays and 7:00 AM to 12:00 AM on Sundays and holidays. Bus service is expected to supplement the remaining hours, making the Hurontario-Main corridor have a 24/7 transit operation. The LRT will take 47 minutes to travel the whole route, compared to 58 minutes using the private automobile.
The LRT vehicle will be 30 metres in length, carrying up to 200 passengers. However, the LRT is planned to have 3-car trains, carrying up to 600 people. This configuration matches the 90-metre platforms to be built for the LRT stations.
Typical Traction Power Substations (TPSS) 
The LRT will have between 15 to 21 substations, which will be distributed evenly throughout the corridor. These substations convert electricity from the local power sources to the levels needed by the LRT vehicles. The LRT will operate on either 750 or 1500 volts of power.

On May 16, 2011, MiWay realigned service along Hurontario to include limited-stop service (Route 202) during Saturdays for passengers wishing to bypass Square One.
In September 6, 2011, Brampton Transit launched its second bus rapid transit line, Route 502 Züm Main, which runs from Sandalwood Parkway to Mississauga City Centre all week long. This route replaced MiWay's 102 Intercity Express. Züm buses run every 10 minutes during rush hours and 20 minutes during off-peak hours and weekends. The frequency of its local counterpart, 2 Main, was reduced to boost ridership in the express service.
At the same date, MiWay replaced 202 Hurontario with a new route, 103 Hurontario Express, which offers additional mid-day and evening services. Its local counterpart, 19 Hurontario, was cut to GO Transit's Highway 407 Park and Ride to fortify the overlapping express services, however its frequency was further increased to address ongoing overcrowding issues between Britannia and Lakeshore Roads, the busiest section of the corridor. 103 Hurontario Express runs every 17.5 minutes during rush hours, 19 minutes during middays and 24 minutes during Saturdays.
Stations and connections 
There are 27 proposed stations throughout the corridor, as well as two potential stations. These proposed stations have an average spacing of 850 metres and will feature 90-metre platforms. They are expected to have heated shelters, CCTV cameras, real-time information system and bicycle lockers. Most of them will feature secondary entrances, but since most of the corridor is currently suburban in nature, these secondary entrances create mid-block crossings throughout Hurontario and Main Streets, which enhance pedestrian access.
