If you’ve been injured in a car accident involving self-driving cars or cars with or driver-assist features in Ontario, you’re not alone in wondering who’s responsible and how compensation works.
Most vehicles on Ottawa’s roads are not fully autonomous. They rely on systems that assist the person behind the wheel rather than replace them. Canada follows the SAE “levels” of driving automation (Level 0 to Level 5). Most consumer vehicles sit at the lower levels and still require close human supervision. These features are often called advanced driver-assistance systems (ADAS), and they support, not replace, the driver.
So, the short answer is that liability still starts with people. In most crashes on Ottawa-area roads, the driver, and often the vehicle owner, are first in line under Ontario’s Highway Traffic Act. Automated features don’t change that starting point.
Manufacturer or software liability can also apply, but only when credible evidence shows a defect caused or contributed to the collision.
Meanwhile, compensation follows the familiar Ontario path: SABS (no-fault accident benefits), tort (a lawsuit for losses SABS can’t cover), and DCPD (property damage with your own insurer).
In the sections below, we explain what Ontario allows on public roads, where responsibility usually lies after a crash involving driver-assist or automated features, how compensation is paid, the evidence to preserve right away, and how MG Law can help protect your health, your claim, and your future.
What Ontario Allows on Public Roads
Ontario permits advanced driving technology on public roads, but with clear guardrails that prioritize safety and responsibility. Everyday features like lane-keeping assist or adaptive cruise control are allowed because they support the human driver rather than replace them. In other words, Ontario treats most on-road technology as ADAS, not full autonomy.
By contrast, vehicles that can handle the full driving task may operate only if specific legal requirements are met, including appropriate liability coverage in Ontario for approved trials.
The starting point for self-driving cars is Ontario’s Automated Vehicles Pilot Project regulation, which states that no one may operate an automated vehicle on a highway unless permitted under the regulation.
The Automated Vehicle (AV) Pilot Sets the Rules
The AV Pilot is Ontario’s framework for real-world trials of higher-automation systems. Participants must apply for approval and follow the pilot’s conditions.
Key conditions include:
- A qualified driver must remain in the driver’s seat and monitor the vehicle, unless the Ministry authorizes driverless testing under additional safeguards.
- Participants must carry substantial liability insurance: $5 million for most vehicles and $8 million for those with seating for eight or more passengers.
- Compliance with collision-reporting and other safety oversight obligations set by the Ministry of Transportation.
What “Driverless” Means in Ontario Trials
Ontario was the first Canadian province to allow public-road testing and expanded it in 2019 to permit driverless trials under tightly defined circumstances. Usually, only select companies in self-driving cars research participate in these trials, and they must meet strict safety and reporting conditions.
For drivers using consumer features like Tesla’s Autopilot, Nissan’s ProPILOT, or similar systems, the legal expectation remains: a person is responsible for the vehicle’s operation under the Highway Traffic Act. This applies alongside the AV Pilot to non-pilot vehicles.
Federal Guidance Frames Canada’s Safety Expectations
Transport Canada complements Ontario’s rules with national guidance for testing and deploying automated driving systems. The Guidelines for Testing Automated Driving Systems in Canada set a baseline, emphasizing:
- Safety assessments
- Operational design domains (where and when the system is meant to work)
- Fallback strategies if the system disengages
- Robust data logging for investigations
In February 2025, Transport Canada released Canada’s Safety Framework for Connected and Automated Vehicles 2.0, updating the national policy and anchoring it to internationally recognized automation definitions.
This guidance shapes how trials are planned, monitored, and documented; important for injured people and their lawyers.
A Separate Pilot for Automated Heavy Trucks
In August 2025, Ontario launched a 10-year Automated Commercial Motor Vehicle (ACMV) Pilot for heavy trucks. It requires at least $10 million in public liability insurance and prompt collision notification to the Ministry.
Limited to approved carriers, this pilot reflects Ontario’s cautious approach. While not relevant to every crash, it shows how safeguards are scaling with the technology.
Who Is Liable in Ontario?
After a crash in Ontario, even one involving self-driving cars or cars with driver-assist features, the law starts with people. The driver is responsible for the vehicle’s operation, and often the owner is liable for the driver’s negligence. These rules come from Ontario’s Highway Traffic Act and remain the foundation for injury claims.
Driver Responsibility
If a vehicle is driven carelessly or breaks road rules and someone gets hurt, the injured person can sue the driver for negligence. This applies whether the driver was steering manually or using a driver-assist feature.
Ontario courts assess what the driver did or failed to do before the collision. The Highway Traffic Act governs vehicle operation on Ontario highways.
Owner Responsibility
Ontario holds owners liable when someone drives their vehicle with consent. The Highway Traffic Act makes owners responsible for loss or damage from negligent operation, unless the vehicle was taken without consent.
This “vicarious liability” ensures injured people can recover when the at-fault driver has limited resources.
What Counts as Consent?
The law focuses on consent to possession, not approval of every use. If the owner handed over the keys, they may be liable even if the driver used the vehicle unexpectedly.
Owners avoid liability only by proving no consent to possession.
How This Interacts with Automated Features
Ontario’s AV Pilot regulation doesn’t replace these basics. It considers the person in the driver’s seat as the driver, whether the system is engaged or not.
Usual Highway Traffic Act rules apply unless narrow driverless authorization is met.
Why This Matters if You’re Injured
In most Ottawa collisions, lawsuits start against the driver and owner. If evidence shows a system defect contributed, manufacturers may be added later.
Ontario law starts with human responsibility and owner liability to give injured people a clear recovery path.
When Manufacturer or Software Liability Applies
While Ontario law starts with human responsibility, facts sometimes support claims against manufacturers or technology providers of self-driving cars. This happens when evidence shows a defect in the automated or driver-assist system caused or contributed to the crash.
Defects can include:
- Design flaws (e.g., poor engineering)
- Manufacturing issues (e.g., failed components)
- Inadequate warnings or instructions (e.g., unsafe if not used as intended)
In modern vehicles, risks also arise from calibration errors, failed updates, or sensor misalignment.
These cases are evidence-heavy. Early investigation seeks:
- Event data recorder (EDR) information
- Automation/ADAS logs
- Fault codes
- Software version history
- Calibration and service records—common in car accident investigations involving sensors or software.
Transport Canada’s testing guidance expects safety assessments, operational domains, fallback strategies, and data logging; guiding evidence lawyers pursue.
Most lawsuits start against drivers and owners. If defects emerge, manufacturers, suppliers, or developers may be added, often with expert input from accident reconstruction and system specialists.
In these cases, preserving data is key. Lawyers will send preservation notices to prevent data loss, aligning with Transport Canada’s data retention emphasis.
If you suspect system failure, early investigation matters. Preserving data, engaging experts, and linking findings to legal standards turn speculation into proof.
What This Means for the Insurance Sector
Canada’s insurance sector is also adapting. The Insurance Bureau of Canada proposes a single-policy model where the at-fault vehicle’s insurer pays injured people first, then pursues manufacturer fault. This is a recommendation, not law, but aims for fair, quick payments as automation grows.
How Compensation Works
A serious collision disrupts life. Medical bills mount, work time is lost, and the process confuses, especially with automated features involved.
In Ontario, compensation for a car accident involving self-driving cars and those with advanced driver-assist systems follows Ontario’s familiar path. Knowing the steps protects your claim and aids recovery.
Step 1: Statutory Accident Benefits (SABS)
Your Immediate Safety Net
Regardless of fault, every Ontario auto policy provides SABS. These cover medical and rehabilitation treatment, income replacement, attendant care, and other supports. You can apply for SABS through your own insurer.
Step 2: The Lawsuit (Tort Claim)
Filling the Gaps SABS Can’t Cover
SABS address immediate needs, but not pain, suffering, or long-term losses. If negligence caused the crash, you could start a lawsuit for additional damages like pain and suffering or future income/care costs.
Step 3: Vehicle and Property Damage
Direct Compensation—Property Damage (DCPD)
Damage to your vehicle and certain contents is typically resolved under DCPD. In most scenarios, you deal directly with your own insurer for repairs, loss of use, or the vehicle’s value, rather than suing the other driver over property loss.
DCPD is a standard part of Ontario auto policies.
Special Situations
Uninsured or Unidentified Vehicles
For a hit-and-run, or if the other driver is uninsured, the Motor Vehicle Accident Claims Fund (MVACF) may pay as a last resort. This program exists so injured people are not left without a path to compensation when insurance coverage is missing.
How the Pieces Fit Together
Most Ontario cases involve both paths: you open a SABS file for medical and income supports, and you pursue a tort claim against the at-fault party to address losses SABS cannot fully cover. Meanwhile, DCPD handles your vehicle damage.
Even when automated or driver-assist features are in play, these compensation steps remain the same; what changes is the evidence you may need if a product issue is suspected.
Evidence to Preserve Immediately
Strong claims are built on clear facts. After a car accident involving self-driving cars or those with automated features, preserve digital and real-world evidence quickly.
On-Board Digital Data
Ask that the vehicle not be moved, altered or powered up until key data can be preserved: EDR downloads, ADAS/automation logs, diagnostic fault codes and software/firmware version history.
These sources can show what the vehicle “thought,” what the sensors saw, when automation was engaged and when an alert or handover occurred. Transport Canada’s guidance anticipates robust data logging for exactly this reason.
Service, Calibration and Update Records
Keep invoices and work orders from dealerships or repair shops for sensor calibration, alignment, and over-the-air updates. These documents can explain why a system failed to detect a hazard.
Scene & Third-Party Evidence
Photograph the scene (skid marks, debris, sightlines, weather, road signs), vehicle damage, and any warning messages on the instrument cluster. Download dash-cam footage and gather witness contacts.
Communication & Insurer Files
Save emails, texts, app notifications and letters with insurers, dealerships and manufacturers. If you opened a SABS claim, request your insurer’s file and keep benefit explanations, medical approvals/denials and assessment notices.
Formal Preservation Requests
Your lawyer can send preservation (litigation-hold) notices to the vehicle owner, dealer, manufacturer and any telematics provider to prevent overwriting of logs or remote deletion during routine updates.
If a Pilot-Approved Automated Vehicle Was Involved
Ontario’s AV Pilot imposes extra collision-reporting and oversight duties. If your crash involved a pilot vehicle, obtain the pilot approval details, the participant’s collision report and any data the participant was required to keep.
Medical Documentation
Seek care promptly and follow through with referrals. Keep discharge summaries, imaging reports, physiotherapy notes and employer absence records.
Aligning the mechanism of injury with medical findings supports both SABS benefits and any lawsuit for additional losses.
