Who Is Responsible for an Injury Near Yonge North Subway Construction?
A crash that occurs near Yonge North Subway Extension construction could be caused entirely by a negligent driver. Metrolinx, York Region or a construction contractor might also be responsible if temporary lanes, barriers, pedestrian routes, equipment or construction work contributed to the injury.
The presence of a construction zone does not establish liability on the part of a construction company. Investigations must identify the precise location, what caused the incident and which organization controlled the road, walkway, transit area or construction operation at the time.
Our Markham personal injury lawyers represent people seriously injured in motor vehicle collisions, pedestrian accidents and other incidents throughout Markham and York Region.
Where Is Yonge North Subway Construction Taking Place?
The Yonge North Subway Extension will extend TTC Line 1 approximately eight kilometres north from Finch Station through Vaughan, Markham and Richmond Hill. The project includes five new stations.
Infrastructure Ontario and Metrolinx awarded the advance-tunnelling contract to North End Connectors in August 2025. The contract includes approximately 6.3 kilometres of twin tunnels extending from Finch Station to an area south of Langstaff Road in Markham, where the route will transition toward the surface.
As of September 2026, construction and preparatory work is occurring at several locations along the future route. Near Yonge Street and John Street, work includes road widening, removal of the centre median, temporary concrete barriers, lane and turn restrictions, relocated bus stops and a shifted pedestrian route. Metrolinx issued a further notice on August 4, 2026 confirming that piling work is beginning on Yonge Street south of John Street.
In the Royal Orchard area, Metrolinx has carried out environmental investigations and other preparatory work around Royal Orchard Boulevard and Kirk Drive. Residential demolitions at Kirk Drive also began in July 2026 as the area is prepared for future subway infrastructure.
Farther north, the south commuter parking lot and passenger pickup and drop-off area at Langstaff GO have been closed for an extended period while utilities are relocated and work sites are prepared for the future Bridge Station.
At High Tech Station in Richmond Hill, Metrolinx currently identifies environmental investigations as being in progress. The station is planned at surface level beneath the High Tech Road bridge within the Richmond Hill Centre area.
Construction conditions will continue to change as the project advances. Metrolinx’s Yonge North Subway construction notices provide current information about work along the route.
Who Is Responsible for a Car Accident Near Yonge North Subway Construction?
Subway construction frequently produces congestion, unfamiliar lane arrangements and sudden slowing. Drivers must still watch the road, leave enough stopping distance and respond safely to temporary conditions.
If traffic stops because a was reduced and a distracted driver strikes the vehicle ahead, the construction may explain the congestion without shifting responsibility away from the driver who caused the collision.
The same principle applies to unsafe lane changes, failure to yield, excessive speed for the conditions or ignoring a temporary traffic restriction.
Someone who is injured in a car accident in Ontario might still be entitled to statutory accident benefits regardless of who caused the collision. A separate lawsuit might also be available against an at-fault driver or another party whose negligence contributed to the injuries.
When Can the Construction Arrangement Contribute to an Accident?
The analysis can change if the temporary road configuration or construction operation itself contributed to the collision.
For example, an investigation might be necessary to determine whether temporary and permanent lane markings conflicted, a concrete barrier interfered with visibility, a lane ended without adequate warning or construction equipment entered live traffic without sufficient control.
An abrupt pavement edge, misplaced sign or material left within an open travel route could also become relevant if it contributed to the accident.
These cases require evidence of more than the existence of construction. The injured person must establish a connection between an unsafe condition or negligent activity and the collision.
Responsibility can also be shared. A driver may have failed to respond reasonably while a contractor or road authority contributed by creating an unreasonable hazard. Where the negligence of two or more parties contributed to an injury, Ontario’s Negligence Act allows responsibility and damages to be apportioned according to their respective degrees of fault.
Construction Around Yonge Street and John Street
The work around Yonge Street and John Street provides a clear example of how the Yonge North project is changing an established York Region road.
Metrolinx has removed portions of the centre median and introduced temporary concrete barriers while Yonge Street is widened on its east side. Lane reductions and turn restrictions are being used around the intersection, traffic signal equipment is being relocated and the east sidewalk is being shifted.
Bus stops are also being moved and temporary pedestrian routes installed.
The work is creating space for an emergency exit building that will connect with the future subway tunnels. Metrolinx says construction of the emergency exit building will continue over several years.
On August 4, 2026, Metrolinx added piling south of John Street to the work taking place in this area. In some cases, the placement of a barrier, a temporary traffic control or the movement of construction equipment could require further investigation.
Royal Orchard and Kirk Drive Construction in Markham
The Royal Orchard area gives the project a particularly strong connection to Markham.
Royal Orchard Station is planned along the Yonge North Subway Extension, and Metrolinx has been carrying out environmental investigations, property work and other preparations in the surrounding community.
In July 2026, residential demolitions began at 128, 130 and 132 Kirk Drive. Metrolinx has identified 130 Kirk Drive as the planned location of an emergency exit building, with the neighbouring properties being used to support construction.
Other work in the Royal Orchard area has included environmental site assessments, tree removals and monitoring connected to future tunnelling.
As construction continues to expand, residents and road users may encounter changes to access, temporary pavement, construction vehicles, modified pedestrian routes and other conditions that did not previously exist.
None of those conditions creates liability simply because it is inconvenient or unfamiliar. A claim requires evidence that negligent driving, construction activity or an unreasonable condition caused or contributed to an injury.
Langstaff GO and the Future Bridge Station
The future Bridge Station will be located between Highway 7 and Highway 407 and connected to the existing Langstaff GO Station.
Metrolinx plans for Bridge Station to provide connections among the subway, Richmond Hill GO trains, GO buses, Viva and local York Region Transit services.
Preparation for the station is already affecting how passengers enter Langstaff GO.
Since April 28, 2026, the south commuter parking lot and passenger pickup and drop-off area have been closed for an extended period. Access to the station and train platform from Langstaff Road and the south lot is also closed. Passengers are being directed to the north parking and pickup area from Red Maple Road.
Metrolinx currently identifies preparation for major construction and utility relocation at Bridge Station as being in progress.
An incident described simply as occurring “at Langstaff GO” may therefore require closer examination. A collision could happen on a surrounding public road, in a parking or pickup area, along a temporary passenger route or on property controlled by Metrolinx or a construction contractor.
Our guide to Highway 7 car accident claims in Vaughan, Richmond Hill and Markham addresses collisions on the surrounding York Region corridor.
High Tech Station and Richmond Hill Centre
High Tech Station will serve the Richmond Hill Centre area at the northern end of the subway extension. Metrolinx plans to construct the station at surface level beneath the High Tech Road bridge over the existing railway corridor. The project is still at an earlier stage here than at some construction areas farther south.
Metrolinx currently lists environmental investigations at High Tech Station as in progress. Preparation for major construction, piling and excavation are later stages on the published construction timeline.
The surrounding Richmond Hill Centre area already contains regional roads, transit services, commuter traffic, new development and pedestrian routes. As subway construction advances, responsibility for an injury will depend on the construction phase and the specific location involved.
An incident which involves a temporary pedestrian route, construction operation or work site may require investigation of Metrolinx, York Region, a contractor or another property controller.

Who Is Responsible for a Pedestrian Injury Near Subway Construction?
Construction can change how pedestrians reach homes, businesses, parking areas and transit stops. A familiar sidewalk may be narrowed, shifted or temporarily replaced.
Ontario’s Occupiers’ Liability Act requires that an occupier to take reasonable care in the circumstances to see that people entering the premises are reasonably safe.
Which organization owes that duty will depend on where the injury occurred. A temporary route may cross a regional road allowance, construction-controlled property, transit property or privately occupied land.
After a pedestrian fall, the condition of the route should be documented before it changes. The investigation may examine the walking surface, lighting, barriers, signs, separation from construction equipment and whether the route could reasonably accommodate the people expected to use it.
Different principles apply when a pedestrian is struck by a motor vehicle.
Section 193 of Ontario’s Highway Traffic Act can place the burden on the motor vehicle’s owner or driver to prove that the injury did not arise through their negligence or improper conduct where the statutory requirements are met.
Further information about serious pedestrian claims is available from our Markham pedestrian accident lawyers.
Cyclists Travelling Through Yonge Street Construction Areas
Construction can also change the space available to cyclists along the Yonge Street corridor. A curb lane or road edge previously used by riders may narrow or end as traffic is shifted around barriers and work areas.
If a cyclist is struck or falls, the investigation may need to determine whether the driver responded safely, whether the rider had adequate warning of the route change and whether the temporary configuration created an unreasonable hazard.
A pavement edge, construction material or barrier may be relevant where it forced a cyclist suddenly into traffic or caused the rider to lose control.
If an automobile is involved, an injured cyclist may still have access to mandatory accident benefits even without personally owning an automobile insurance policy. Since Ontario’s July 2026 automobile insurance reforms, the scope of other benefits can depend on the insurance policies and optional coverages that apply to the injured person.
Who Could Be Responsible for a Yonge North Subway Construction Injury?
The organization which is responsible for the overall subway extension is not necessarily the organization responsible for the condition that caused a particular injury.
Metrolinx is delivering the project, while major work is divided among contractors and subcontractors. York Region has responsibilities for regional roads. GO Transit or York Region Transit may control different transit operations, while adjoining land may be controlled by a private occupier.
Depending on what happened, a claim could involve a negligent driver, Metrolinx, York Region, Markham, Richmond Hill, North End Connectors, another contractor or subcontractor, a transit provider, a property occupier or several parties together.
Infrastructure Ontario and Metrolinx are also delivering advance tunnelling separately from the future stations, rail and systems contract. A contractor working on one part of the extension should not be assumed to control a condition at another site.
The investigation should identify who was responsible for the specific road configuration, work site, equipment or property involved in the injury.
Who Controls Yonge Street in the Construction Corridor?
Yonge Street is a York Regional road along the affected subway-extension corridor in Markham and Richmond Hill. That makes York Region the relevant municipal road authority where a claim concerns the condition or repair of that portion of Yonge Street itself. A nearby local street, sidewalk, transit facility or construction site may be controlled by someone else.
Section 44 of Ontario’s Municipal Act, 2001 requires a municipality to keep highways and bridges under its jurisdiction in a state of repair that is reasonable in the circumstances.
A municipal highway claim generally requires proof that the highway was in a state of non-repair, that the municipality failed to meet the applicable standard and that the condition caused or contributed to the injury.
Municipalities also have statutory defences, including a defence based on compliance with Ontario’s minimum maintenance standards where the requirements of the legislation are met.
A contractor could separately be responsible for negligent construction or traffic-control work. Municipal road jurisdiction does not decide the liability of every other organization involved in a construction project.
The 10-Day Municipal Notice Requirement
A very short notice period can apply when an injury claim is based on a municipal highway or bridge being in a state of non-repair.
Section 44(10) of the Municipal Act, 2001 generally requires written notice of the claim and injury within 10 days after the occurrence. The notice must include the date, time and location of the incident.
Because Yonge Street is a York Regional road along the project corridor, a claim concerning its state of repair may require notice to The Regional Municipality of York rather than the City of Markham or Richmond Hill.
The 10-day requirement does not apply merely because an accident happened near construction. A lawsuit against a negligent driver is different from a statutory municipal highway claim, and claims against contractors or other defendants can be governed by different provisions.
Late notice does not automatically defeat every municipal claim. The Municipal Act, 2001 permits an action to proceed where there is a reasonable excuse for the delay and the municipality has not been prejudiced in its defence.
Evidence Can Disappear as Construction Changes
Yonge North construction sites can change quickly. Barriers could be relocated, signs replaced, pavement completed and pedestrian routes moved before an injured person begins a legal claim.
Photographs should therefore show more than the damaged vehicle or immediate hazard. They should establish where the incident occurred in relation to the street, barriers, lane markings, construction entrance and surrounding landmarks.
The exact date is equally important because Metrolinx publishes construction notices for particular stages of work.
Other evidence may include dashcam footage, witness information, police or transit reports and the names displayed on nearby construction equipment or fencing.
For a serious or disputed claim, further investigation may require traffic-management plans, road-occupancy permits, inspection records, daily site reports, contractor records and communications concerning changes to the location.
Frequently Asked Questions
Is Metrolinx responsible for every accident near Yonge North Subway construction?
No. A collision which occurs near the project could still result entirely from negligent driving. Metrolinx or a contractor becomes relevant where project work, property or an unsafe temporary arrangement under its control contributed to the injury.
Can a driver and a construction contractor both be responsible?
Yes. Responsibility can be divided if the negligence of more than one party contributed to an injury. A driver may fail to respond safely while a contractor also contributed by creating an unreasonable hazard.
Is Yonge Street controlled by Markham or Richmond Hill?
Along the Yonge North Subway Extension corridor in Markham and Richmond Hill, Yonge Street is a York Regional road. Local streets and other properties can have different responsible authorities.
Should municipal notice be sent after every construction-zone accident?
No. The 10-day notice provision discussed above concerns claims based on a municipal highway or bridge being in a state of non-repair. Different claims can have different requirements.
Can a pedestrian or cyclist receive accident benefits after being struck by a vehicle?
Yes. Mandatory accident benefits remain available to people injured in Ontario automobile accidents, including pedestrians and cyclists. A person who does not have an automobile policy of their own may still be able to make a claim through another applicable insurer or, in some circumstances, Ontario’s Motor Vehicle Accident Claims Fund. The availability of optional benefits after the July 2026 reforms depends on the applicable coverage.
What if the construction setup has changed since the accident?
Contemporaneous photographs, witnesses and the Metrolinx notice in effect on the date can help establish the earlier configuration. Construction records and traffic-management documents may also need to be preserved.
How long does someone have to start a lawsuit?
Ontario’s Limitations Act, 2002 generally establishes a two-year limitation period from discovery of a claim. Earlier notice requirements can apply depending on the defendant and legal basis of the case.
