An impaired driving collision can leave victims facing serious injuries, emotional distress, lost income and unexpected expenses. Although the impaired driver may be charged with a criminal offence, the criminal case does not automatically compensate the people injured in the collision.
An injured person may need to pursue insurance benefits, a civil claim or both. These processes serve different purposes and may proceed separately from the criminal prosecution.
Ontario’s automobile insurance laws apply to collisions in Ottawa. However, the facts of the crash, the available insurance coverage and the severity of the injuries will determine which forms of compensation may be available.
Criminal Charges and Civil Claims Are Different Proceedings
Impaired driving is addressed through Canada’s criminal justice system. Police investigate the driver’s conduct, and prosecutors decide whether to pursue charges under the Criminal Code.
A criminal prosecution is intended to determine whether the accused committed an offence and, if so, what sentence should be imposed. The prosecution does not ordinarily recover all of an injured person’s financial and personal losses.
A civil claim has a different purpose. It allows an injured person to seek compensation from a driver or another legally responsible party.
The two proceedings may arise from the same collision, but they involve different legal questions and standards of proof. A civil claim may still be possible even if the impaired-driving charge is withdrawn, reduced or does not result in a conviction.
Similarly, a criminal conviction does not automatically establish the amount of compensation owed to an injured person. The claimant must still prove the nature of the injuries, the connection between those injuries and the collision, and the resulting losses.
Who May Bring a Civil Claim?
A civil claim may be available to anyone who was injured because of the collision, including:
- A driver or passenger in another vehicle
- A passenger travelling with the impaired driver
- A pedestrian or cyclist
- A motorcyclist
- A family member bringing a claim after a serious injury or death
A person’s relationship with the impaired driver does not necessarily prevent a claim. For example, a passenger injured while being driven by a friend or relative may still have legal rights.
However, knowingly entering a vehicle with a driver who appeared impaired could become relevant when fault is assessed. The defence may argue that the passenger failed to take reasonable care for their own safety. This does not necessarily eliminate the claim, but it could reduce the compensation awarded, depending on the evidence.
What Must Be Proven in a Civil Claim?
The injured person generally needs to establish that the other driver acted negligently and that this conduct caused or contributed to the injuries.
Evidence of alcohol or drug impairment may be highly relevant, but impairment is not the only issue. A civil claim may also examine whether the driver:
- Was speeding
- Disobeyed a traffic signal
- Followed another vehicle too closely
- Failed to remain in the proper lane
- Drove too quickly for the weather or road conditions
- Failed to keep a proper lookout
- Lost control of the vehicle
The claimant must also connect the collision to the losses being claimed. Medical evidence may be required to show that an injury was caused or aggravated by the crash.
Does a Criminal Conviction Help the Civil Case?
A conviction or guilty plea may become important evidence in a related civil proceeding. Police reports, breath or blood test results, witness statements, collision-reconstruction evidence and findings from the criminal case may also assist in establishing how the collision occurred.
However, civil responsibility is not determined solely by the impaired-driving charge. The civil court may still examine whether another driver, a road condition, a mechanical failure or some other factor contributed to the crash.
The injured person should not assume that it is necessary to wait until the criminal case is completed before obtaining legal advice or beginning the insurance process. Important civil and insurance deadlines may continue to run while the criminal proceeding is underway.
Accident Benefits May Be Available Regardless of Fault
Ontario uses a no-fault accident-benefits system. This means that someone injured in an automobile accident may apply for certain benefits through an automobile insurer without first proving that another driver caused the collision.
The benefits available under Ontario’s Statutory Accident Benefits Schedule may include assistance with:
- Medical and rehabilitation expenses
- Income replacement
- Attendant care
- Certain caregiving or housekeeping expenses
- Funeral expenses
- Death benefits for eligible family members
Eligibility and benefit limits depend on the policy, the claimant’s circumstances and the medical classification of the injuries.
An innocent driver, passenger, pedestrian or cyclist does not lose the right to seek accident benefits merely because the at-fault driver was impaired.
Different considerations may apply when the person applying for benefits was the impaired driver. The Statutory Accident Benefits Schedule contains exclusions that can restrict certain benefits when the insured person was convicted of specified driving offences. Because the exact effect depends on the benefit and the circumstances, the exclusion should not be interpreted as eliminating every possible benefit without a careful review.
A Civil Claim May Provide Additional Compensation
Accident benefits and a civil claim are related but distinct. Accident benefits provide access to specified benefits under an insurance policy, while a civil claim seeks damages from the person or parties legally responsible for the collision.
Depending on the circumstances, a civil claim may seek compensation for:
- Pain, suffering and loss of enjoyment of life
- Past and future income loss
- Loss of earning capacity
- Medical, rehabilitation and attendant-care expenses
- Future care requirements
- Housekeeping and home-maintenance losses
- Damage to personal property
- Out-of-pocket expenses
- Losses experienced by eligible family members
Ontario’s Insurance Act places restrictions on claims for pain, suffering and certain health-care expenses arising from automobile collisions. In many cases, the injured person must demonstrate a permanent serious impairment of an important physical, mental or psychological function, or permanent serious disfigurement.
Statutory deductibles may also apply to some non-pecuniary damage awards. The applicable rules and amounts can change, so a claim must be assessed using the law in force at the relevant time.
Family Members May Have Their Own Claims
When a person is seriously injured or killed, certain relatives may be entitled to pursue claims under Ontario’s Family Law Act.
Depending on the situation, a family member’s claim may include losses connected with:
- Nursing or caregiving services provided to the injured person
- Travel expenses incurred while visiting or assisting them
- Lost income resulting from providing care
- Funeral expenses
- Loss of care, guidance and companionship
These are sometimes called derivative claims because they arise from the injury or death of another person. Their value depends on the relationship, the effects of the collision and the evidence supporting the claimed losses.
What If the Impaired Driver Was Uninsured?
The absence of valid insurance does not always leave an injured person without a potential source of compensation.
Ontario automobile policies include uninsured automobile coverage. Depending on the circumstances, an injured person may be able to make a claim through their own policy or another applicable policy.
When no insurance is available, Ontario’s Motor Vehicle Accident Claims Fund may serve as a payer of last resort. The Fund has specific eligibility requirements, procedural rules and payment limits. It is not a substitute for available automobile insurance.
Identifying every potentially applicable policy is important, particularly when the driver did not own the vehicle or was operating it without permission.
Can Other Parties Be Held Responsible?
The impaired driver is often the primary defendant, but the investigation may reveal that another person or organization shares responsibility.
Possible additional defendants may include:
- The vehicle’s owner
- An employer whose employee was driving during work
- A business responsible for maintaining a commercial vehicle
- Another driver who contributed to the collision
- A municipality or contractor responsible for an unsafe road condition
Liability against these parties is not automatic. Each claim requires evidence connecting the party’s conduct or legal responsibility to the collision.
Claims involving a municipality can also involve shorter notice requirements and special procedural rules. A person injured on a public road should therefore obtain advice promptly if poor maintenance, missing signs, defective traffic controls or another road-related issue may have contributed to the crash.
What Evidence Should Be Preserved?
Evidence can disappear quickly after a collision. Vehicles may be repaired, surveillance recordings may be erased and witnesses may become difficult to locate.
Useful evidence may include:
- Police occurrence and collision reports
- Photographs or video of the vehicles and scene
- Dash-camera recordings
- Names and contact details of witnesses
- Medical records and diagnostic results
- Ambulance and hospital records
- Employment and income documents
- Receipts for treatment, medication, transportation and assistance
- Notes describing symptoms and their effect on daily activities
- Correspondence with insurers
- Information about the impaired-driving prosecution
An injured person should provide accurate information to medical professionals and attend recommended appointments. Gaps in treatment or incomplete descriptions of symptoms can make it more difficult to demonstrate the progression and effect of an injury.
Social media activity should also be approached carefully. Photographs, videos and written posts may be reviewed by insurers or defence representatives and presented without their original context.
How Long Do You Have to Start a Claim?
Ontario’s Limitations Act, 2002 establishes a basic two-year limitation period for many civil claims. The period generally begins when the claim was discovered or reasonably should have been discovered.
That rule has exceptions, and not every deadline is calculated in the same way. Claims involving minors, people who are legally incapable, municipalities, unidentified drivers or accident-benefit disputes may involve different requirements.
Insurance policies also impose notice and application deadlines. According to the Financial Services Regulatory Authority of Ontario’s accident-claims guidance, policyholders should report a collision to their insurer promptly and follow the required claims process.
Waiting for the criminal prosecution to finish can put a civil or insurance claim at risk. The safest approach is to determine the applicable deadlines as soon as possible after the collision.
What Happens During the Civil Claims Process?
A motor vehicle injury claim commonly begins with notification to the relevant insurers and the collection of medical, employment and collision evidence.
Before starting a lawsuit for personal injuries arising from an automobile accident, Ontario’s Insurance Act requires the claimant to provide written notice of the intention to bring an action. The parties may then exchange information and explore whether the matter can be resolved.
If a settlement is not reached, the injured person may commence a court proceeding. The case can involve documentary disclosure, examinations for discovery, medical assessments, expert evidence and settlement discussions. Some cases resolve through negotiation or mediation, while others proceed to trial.
Civil claims valued within the monetary jurisdiction of Ontario’s Small Claims Court may be heard there. As of August 2026, the Ontario Superior Court of Justice states that Small Claims Court hears civil claims of up to $50,000. Larger or more complex personal injury claims are generally brought in the Superior Court of Justice.
Compensation Depends on Evidence, Not the Driver’s Conduct Alone
Impaired driving is serious misconduct, but the value of a civil claim is not determined simply by how unacceptable the driver’s behaviour was.
Compensation usually depends on factors such as:
- The severity and permanence of the injuries
- The claimant’s medical history
- The effect on employment and earning ability
- Future treatment and care needs
- The claimant’s ability to perform household and personal activities
- Whether the claimant contributed to the collision or injuries
- The amount and type of insurance coverage available
- The strength of the medical and financial evidence
In exceptional cases, a claimant may seek punitive damages based on particularly wrongful conduct. Such awards are not automatic in impaired-driving cases and are generally reserved for conduct that warrants punishment beyond ordinary compensatory damages.
Taking Action After an Impaired Driving Collision
Someone injured by an impaired driver in Ottawa may have rights under both Ontario’s accident-benefits system and the civil justice system. A criminal prosecution may provide useful evidence, but it does not replace the injured person’s own claim for compensation.
Promptly reporting the collision, obtaining medical care, preserving evidence and identifying the relevant deadlines can help protect those rights. Because motor vehicle claims involve detailed insurance rules and fact-specific legal questions, an injured person may wish to speak with an Ontario lawyer before signing a release, accepting a settlement or allowing a limitation period to expire.
Legal note: This article provides general information about Ontario law and is not legal advice. The rights and deadlines that apply depend on the facts of the collision, the insurance policies involved and the law in force at the relevant time. Anyone injured in an impaired driving collision should seek advice from a qualified Ontario lawyer about their specific circumstances.
