Legal News: Snowplows, Salters & Private Contractors: Who’s Liable After a Winter-Operations Crash?

Understanding Fault in Snowplow, Salter, and Winter-Operations Collisions Across Canada

Every Canadian knows that winter driving comes with its own set of hazards, but few collisions are as complicated as those involving snowplows, salters, and private winter-maintenance contractors. These vehicles operate in harsh weather, often in low visibility, and frequently stop or swerve unpredictably. On top of this, impatient drivers may try to pass these slow moving heavy vehicles, putting themselves at risk unnecessarily. When a crash happens, determining liability becomes a tangled mix of municipal responsibility, contractor agreements, and driver conduct.

For injured victims, understanding who may be legally at fault is critical—especially when navigating insurance disputes or seeking compensation with the help of a personal injury lawyer in Toronto.

This article breaks down how liability works, what evidence matters, and how injured people can protect their rights after a winter-operations accident.

Why Winter-Operations Collisions Are So Complex

Unlike standard motor-vehicle accidents, winter-operations crashes often involve:

• Government vehicles working under statutory protections
• Private contractors with shifting responsibilities
• Real-time decision-making in dangerous weather
• Unique equipment with blind spots and limited stop times

Because of these factors, determining fault requires a thorough investigation, sometimes involving expert analysis, maintenance logs, winter-operations standards, and municipal contracts.

When Municipalities Can Be Liable

Most Canadian municipalities manage at least some portion of winter road maintenance. Under provincial laws such as Ontario’s Municipal Act, cities must keep roads in a “reasonably safe condition.” Failure to meet this duty can result in municipal liability—but only under specific circumstances.

Municipalities may be liable when:

1. They fail to meet minimum road-maintenance standards

If a road wasn’t plowed or salted within the timeframes required by provincial guidelines like Ontario’s Minimum Maintenance Standards, the municipality could be considered negligent.

2. Winter-maintenance vehicles were operated carelessly

Although plow operators get leeway to move slowly, cross lanes, reverse, or stop suddenly, their actions must still be reasonable.

Examples of negligent operation include:

• Backing up without checking blind spots
• Operating with non-functioning safety lights
• Failing to properly secure equipment

3. The municipality ignored complaints or known hazards

If citizens reported icy roads repeatedly—or if the city already knew of a problem area—and still failed to respond promptly, liability becomes more likely.

How Evidence Helps Prove Municipal Fault

Municipal investigations often require technical evidence, such as:

Maintenance Logs

These records track salting, sanding, plowing times, and road temperature readings. Missing or incomplete logs can suggest negligence.

GPS Tracking Data

Most plow and salter vehicles have GPS systems showing their routes, speeds, and stop points. This information can reveal whether operators followed protocol.

Dashcam Footage

More drivers than ever rely on dashcams, which often become crucial in showing:

• Lane changes during plowing
• Proximity of vehicles
• Traffic-light behaviour
• Visibility and weather conditions

Because municipal defendants tend to have strong legal teams and heightened evidentiary protections, working with knowledgeable personal injury lawyers becomes essential.

When Private Contractors Can Be Liable

Many cities outsource road maintenance to private contractors for subdivisions, parking lots, commercial plazas, and rural roads. In these cases, liability often depends on the contractual wording between the city and the contractor.

Private contractors may be liable when they:

1. Fail to follow contract requirements

If the contract requires salting within 60 minutes of snowfall and the contractor waited two hours, the delay may be deemed negligent.

2. Perform the job incorrectly or dangerously

This includes:

• Damaging road surfaces
• Over-salting or under-salting
• Failing to clear intersections or crosswalks
• Leaving windrows in dangerous spots

3. Cause collisions due to negligent vehicle operation

A plow driver employed by a private company may be responsible for:

• Improper reversing
• Swinging the blade into traffic
• Driving without proper lighting
• Failing to clear mirrors or use spotters

Contractors have fewer statutory protections than municipalities, making lawsuits against them more straightforward.

Evidence Used to Establish Contractor Negligence

• Employee time sheets
• On-board vehicle data
• Winter-maintenance schedules
• Internal dispatch records
• Surveillance footage from nearby properties

Contractor liability frequently overlaps with municipal responsibility, especially when both parties share maintenance duties.

When Drivers Can Be Liable

Not all winter-operations collisions are the fault of plows or cities. In many cases, private motorists contribute to or entirely cause the crash.

Drivers may be liable if they:

• Tailgate a plow (a common issue, since plows can throw snow backward)
• Ignore flashing amber lights
• Attempt to pass a plow in poor visibility
• Brake suddenly in front of a salter
• Fail to maintain winter tires or safe driving practices

Winter-maintenance vehicles have extremely limited visibility, and their stopping distances are far longer due to size and weight. Courts often consider these factors when assessing fault.

Shared Liability Is Common

In many cases, more than one party shares responsibility. For example:

• A municipality may have delayed salting a roadway.
• The contractor’s plow driver may have reversed improperly.
• The injured driver may have been travelling too fast for the conditions.

Canadian courts apportion fault based on percentage responsibility, which then affects how much compensation a victim can receive.

What Victims Should Do After a Winter-Operations Crash

If you’re involved in a collision with a plow, salter, or winter-maintenance contractor, taking early action is crucial.

Steps to protect yourself:

• Report the collision immediately to police and your insurer.
• Take pictures and video of the scene, vehicle damage, weather, and road conditions.
• Identify the operator — municipal worker or private contractor.
• Save dashcam footage before it is overwritten.
• Get witness information (drivers, pedestrians, homeowners).
• Speak with a Personal Injury Lawyer Toronto team that understands municipal and contractor liability.

Municipal claims also have strict notice periods under provincial legislation—sometimes as short as 10 days—so acting quickly is essential.

How Personal Injury Lawyers Help in These Cases

Experienced personal injury lawyers help victims by:

• Obtaining maintenance logs and GPS records
• Analyzing municipal standards and contractor agreements
• Working with crash-reconstruction engineers
• Challenging municipal or contractor defences
• Ensuring deadlines are met for municipal notice requirements
