A Guide to Personal Injury Lawsuits in Ontario

When someone’s carelessness leaves you hurt, a personal injury lawsuit is the formal legal path to get the compensation you deserve. At its core, this process is about accountability—making sure the person responsible for your injuries is held accountable for the harm they’ve caused. It’s important to remember this is a civil claim, completely separate from the criminal justice system.

Understanding the Goal of an Injury Lawsuit

Think of an unexpected injury like a debt you never agreed to take on. Suddenly, you’re facing medical bills, time off work, and constant pain—all costs you’re forced to bear. In Ontario, a personal injury lawsuit is how you legally shift that “debt” back to the person or company whose negligence put it on you in the first place.

The main purpose is to recover financial compensation, which the law calls ‘damages.’ This isn’t about hitting the lottery; it’s about making you whole again. The legal system’s goal is to restore you, as much as possible, to the financial position you were in before the accident ever happened.

The Two Pillars of a Successful Injury Claim

To get there, your case needs to be built on two solid legal pillars. You can’t have one without the other; they are the foundation of your entire claim. If one pillar is weak, the whole thing comes crashing down.

Here’s a quick breakdown of what you need to prove for a successful personal injury case in Ontario.

| The Two Pillars of a Successful Injury Claim | | --- | --- | | Legal Pillar | | Liability | | Damages |

These two pillars are non-negotiable. For instance, proving a distracted driver ran a red light establishes liability. Proving the crash gave you a spinal injury that requires surgery and prevents you from working establishes damages. You need both to have a case.

A personal injury lawsuit is fundamentally a story told through evidence. The stronger your evidence for both liability and damages, the more compelling your story becomes, increasing the likelihood of a successful outcome.

Why This Matters for Ontarians

Here in Burlington, the GTA, and across Ontario, our civil justice system provides a clear roadmap for injured people to seek justice. Without it, victims would be left to carry the immense financial and personal burden of an accident that wasn’t their fault.

Getting a firm grasp on these two key concepts—liability and damages—is the critical first step in protecting your rights and starting the journey toward recovery.

Common Types of Personal Injury Claims in Ontario

The world of personal injury law is vast. It essentially covers any situation where someone gets hurt because another person was careless or negligent. But not all personal injury lawsuits are cut from the same cloth; each type has its own set of rules, challenges, and legal nuances.

Figuring out which category your injury falls into is the critical first step. A crash on the QEW is handled very differently from a fall on an icy patch of sidewalk outside a shop. Here in Ontario, a few specific types of claims show up far more often than others.

Motor Vehicle Accidents

It’s no surprise that accidents involving cars, trucks, and motorcycles are one of the leading causes of personal injury claims across the Greater Toronto Area. The legal process for these incidents is a bit unique in Ontario because we have a two-part system.

First, there’s the “no-fault” side of things, officially known as the Statutory Accident Benefits Schedule (SABS). It doesn’t matter who caused the collision; you’re entitled to certain benefits from your own insurance company for things like medical treatment, rehabilitation, and lost income.

But what if your injuries are serious and permanent? That’s where the second part comes in. You might have the right to file a separate lawsuit (called a tort claim) against the at-fault driver. This action lets you seek compensation for pain and suffering, as well as financial losses that SABS doesn’t cover.

Slip and Fall Incidents

When you walk into a store in Burlington, a park in Hamilton, or a friend’s apartment building in Toronto, you should be able to assume the property is reasonably safe. Slip and fall claims happen when that basic expectation isn’t met, and the legal basis for them is Ontario’s Occupiers’ Liability Act.

This law puts the responsibility on property owners to take reasonable care to keep people safe. To win a claim, you have to show that the owner either knew about a hazard—like a freshly mopped floor without a sign, an icy walkway, or a wobbly handrail—or should have known about it and did nothing to fix it. If you want to dive deeper, you can explore our guide on slip and fall compensation.

A successful slip and fall case isn’t just about proving you got hurt on someone else’s property. It’s about proving the owner was negligent in their duty to protect you from a danger they should have anticipated.

Long-Term Disability Denials

It’s a gut-wrenching scenario: you’ve paid into a long-term disability (LTD) policy for years, only to have the insurance company deny your claim when you need it most. These cases aren’t about an accident; they’re about an insurer breaking its contractual promise to you.

Suing an insurance company means proving your medical condition fits the policy’s definition of “total disability.” This battle often requires a mountain of medical evidence and a sharp understanding of insurance law to overturn a wrongful denial and get you the benefits you’re rightfully owed.

Other Significant Claim Types

While the three above are the most common, they are by no means the only ones. Other serious incidents can also lead to personal injury lawsuits in Ontario, and each one demands its own specific strategy.

• Product Liability: When a defective product causes harm—whether it’s a malfunctioning appliance or contaminated food—the manufacturer, distributor, or even the store that sold it can be held responsible.
• Medical Malpractice: These are incredibly complex cases. They arise when a doctor, nurse, or other healthcare professional’s actions don’t meet the accepted standard of care, causing direct harm to a patient.
• Dog Bite Incidents: Ontario’s Dog Owners’ Liability Act is quite clear. It holds owners strictly liable for bites and attacks, which means you often don’t have to prove the owner was negligent, only that their dog caused the injury.

From a car accident to a denied disability claim, navigating the specifics of your case starts with a clear understanding of the laws that apply. Knowing where you stand is the foundation for achieving a just outcome.

How to Prove Fault and Establish Liability

Winning a personal injury lawsuit in Ontario isn’t just about showing you were hurt; it’s about proving someone else is legally responsible for that harm. Think of this as the engine that drives your entire claim forward. At the core of most cases, you’ll find a legal concept called negligence.

So, what is negligence? In simple terms, it’s just a legal word for carelessness. It means someone had a responsibility to act with reasonable care, they failed to do so, and that specific failure led directly to your injuries. It’s like a four-part recipe—you need every single ingredient to successfully prove your case.

The Four Ingredients of Negligence

To convince a court in Ontario of negligence, your lawyer has to clearly establish four key elements. If even one is missing, the whole claim can fall apart. These elements give your case its structure.

1. A Duty of Care Was Owed: This simply means the other person had a legal obligation to act in a way that wouldn’t put you in harm’s way. For example, every driver on an Ontario road automatically has a duty of care to everyone else out there—other drivers, pedestrians, cyclists, you name it.
2. The Duty of Care Was Breached: The person didn’t live up to that legal obligation. This is the careless act itself. A driver texting behind the wheel or a shop owner ignoring a big spill on the floor are both clear breaches of their duties.
3. Causation: This is the crucial link. You have to prove that the breach directly caused your injuries. The car crash must be the reason for your broken leg, not something that happened later or a pre-existing condition.
4. Damages Were Suffered: You have to show you’ve suffered actual, measurable losses. This isn’t just about the injury itself, but also the consequences: medical bills, lost income, and the real physical and emotional toll of your pain and suffering.

Let’s picture a grocery store in Burlington. The owner has a duty to keep the aisles safe for shoppers. An employee mops the floor but forgets to put out a “wet floor” sign (the breach). You walk by, slip, and break your wrist (causation), leading to medical bills and time off work (damages). See? All four ingredients are there.

The Role of Contributory Negligence in Ontario

But what if you were a little bit careless, too? Life isn’t always black and white, and Ontario law gets that. This is where the concept of contributory negligence comes into play. It recognizes that sometimes, the fault is shared.

For instance, say you were driving slightly over the speed limit when another driver blew through a red light and hit you. A court might decide you were partially responsible for the severity of the crash. If they determine you were 10% at fault, your final compensation award would simply be reduced by that amount. You can still get compensation—just not the full 100%.

The important thing to remember is that being partially at fault doesn’t kill your claim in Ontario. The law is designed to fairly split the responsibility, making sure the person who was more at fault is held accountable for their share.

Gathering Evidence to Build a Powerful Case

Proving all of this takes more than just your side of the story. A strong personal injury claim is built on a foundation of solid, objective evidence. Your legal team basically becomes a team of investigators, gathering all the pieces of the puzzle to paint a clear picture of what happened.

Some of the most critical pieces of evidence often include:

• Police and Accident Reports: These create an official, on-the-scene record of what happened, especially in traffic collisions.
• Witness Statements: What other people saw can be incredibly powerful in confirming the key details of how the incident unfolded.
• Photographs and Video Footage: In today’s world, this is huge. Surveillance cameras, dashcams, or even just photos you snapped at the scene can provide undeniable proof of a hazard or a negligent act.
• Expert Reports: For more complicated cases, we might bring in engineers, accident reconstruction specialists, or medical experts to provide a professional opinion.

Knowing what evidence to look for after a collision is crucial. You can dive deeper by reading our guide on motor vehicle accident compensation. Each piece helps connect the dots, turning an unfortunate event into a powerful legal argument for why you deserve to be compensated.

The Journey of a Personal injury Lawsuit

Starting a personal injury lawsuit can feel overwhelming, like navigating a complex maze without a guide. Knowing the steps involved can make the entire experience feel more manageable and less intimidating. The process isn’t random; it’s a structured journey designed to ensure a fair and informed resolution for everyone involved.

This visual gives you a bird’s-eye view of the three main phases of a personal injury claim, from the initial incident right through to the final outcome.

As you can see, the process starts the moment an injury occurs and usually ends with a negotiated settlement, not a courtroom battle.

The First Steps: Consultation and Investigation

Your journey begins with an initial consultation with a personal injury lawyer. This meeting is free of charge and comes with no strings attached. It’s your chance to tell your story and for the lawyer to evaluate whether you have a solid case based on legal principles like liability and damages.

If the lawyer agrees to represent you, the investigation stage kicks off. This is where your legal team gets to work, gathering all the puzzle pieces needed to build a powerful case. This behind-the-scenes work includes collecting police reports, your medical files, statements from any witnesses, and reports from experts.

Making It Official: Filing the Claim and Discovery

With enough evidence in hand, your lawyer formally launches the lawsuit by filing a Statement of Claim with the court. This is the official document that lays out what happened, who you believe is at fault (the defendant), and the compensation you’re seeking for your injuries.

Once the claim is filed, we move into the discovery phase. Think of this as a structured “show and tell” where both sides must share all the information and evidence they have. The goal is to make sure there are no surprises down the road.

In Ontario, the discovery process typically involves:

• Affidavit of Documents: Each party provides a sworn list of every relevant document they have.
• Examinations for Discovery: This is where the opposing lawyer gets to ask you questions under oath. It’s a chance for them to understand your side of the story directly from you.

This full disclosure is crucial. It helps everyone understand the strengths and weaknesses of the case, which often clears the path toward a fair settlement.

Many people assume that filing a lawsuit automatically means you’re headed to court. The reality is quite different. In Ontario, well over 95% of personal injury cases are settled before ever reaching a trial. The system is built to encourage resolution.

Finding Common Ground: Mediation and Negotiations

In many jurisdictions across Ontario, including major centres like Toronto and Hamilton, mandatory mediation is a required step before a case can go to trial. This is a confidential meeting where a neutral professional—the mediator—helps guide a conversation between you and the other side to see if you can agree on a settlement.

Mediation is often the single best chance to resolve your case. It provides a more relaxed, less formal environment than a courtroom for serious negotiation. Your lawyer will be your champion, using all the evidence gathered to argue for the maximum compensation you deserve. Our team has helped clients from Burlington across the GTA, and learning how a skilled personal injury lawyer in Hamilton, Ontario can support you is a great next step.

If you reach an agreement, the lawsuit concludes. If not, the case proceeds toward trial. But given the significant time, expense, and unpredictability of a trial, both sides are usually motivated to find a resolution through negotiation, making it the most common end to the legal journey.

Here’s a look at what a typical timeline might look like for a case in Ontario.

Typical Timeline for an Ontario Injury Lawsuit

Every personal injury case is unique, and the timeline can shift based on the complexity of the injuries and the specifics of the incident. However, this table provides a general estimate of how long each major stage can take.

Milestone	Typical Duration	Key Activities
Initial Investigation	1-4 Months	Collecting medical records, police reports, and witness statements.
Pleadings & Discovery	6-18 Months	Filing the Statement of Claim; exchanging documents; Examinations for Discovery.
Mediation	1-2 Months	Preparing for and attending mandatory mediation to attempt a settlement.
Pre-Trial & Trial Prep	6-12+ Months	If no settlement, preparing for trial, attending pre-trial conferences.
Trial	1-4 Weeks	Presenting evidence and arguments before a judge (occurs in <5% of cases).
Resolution/Settlement	Varies	Can occur at any stage, but most common after discovery or mediation.

Keep in mind that these are just estimates. A straightforward case might resolve in a year, while a more complicated one could take several years to see through to its conclusion. An experienced lawyer can give you a more personalized projection based on your specific situation.

How Compensation Is Calculated in Ontario

After you’ve been injured because of someone else’s carelessness, the big question is always, “What is my claim actually worth?” In Ontario, there’s no simple formula. Instead, compensation, legally known as ‘damages’, is broken down into two main categories. Each one is designed to cover a very different type of loss you’ve suffered.

Think of it like rebuilding a house after a storm. You need money to repair the physical structure and replace your belongings—the tangible losses. But you also have to account for the emotional toll and the disruption to your life. Personal injury compensation works on a similar principle.

Pecuniary Damages: Rebuilding Your Financial Foundation

The first and most straightforward category is pecuniary damages. This is all about the cold, hard numbers—the concrete, out-of-pocket financial losses you’ve already faced and will continue to face because of your injury. The goal is simple: to put you back in the financial position you would have been in if the accident had never happened.

These damages cover every single calculable cost that flows from your injury. It’s a detailed accounting of your finances before and after the incident.

Common examples of pecuniary damages include:

• Past and Future Income Loss: Often the largest part of a claim, this covers the paycheques you’ve missed and the money you’ll lose in the future if your ability to earn a living is compromised.
• Medical and Rehabilitation Costs: This includes all the treatments not covered by OHIP or your private benefits, like physiotherapy, prescriptions, counselling, and chiropractic care.
• Future Care Costs: For life-altering injuries, this is crucial. It provides funds for long-term needs such as attendant care, home modifications like wheelchair ramps, specialized medical equipment, and ongoing therapies.
• Out-of-Pocket Expenses: This bucket catches all the smaller but still significant costs, from mileage for medical appointments to paying for help with housekeeping or buying assistive devices.

To figure out these amounts, your legal team will bring in experts—accountants, vocational specialists, and occupational therapists—to project these costs accurately over your entire lifetime.

Non-Pecuniary Damages: Acknowledging Your Pain and Suffering

The second category is non-pecuniary damages, which you’ve probably heard referred to as compensation for pain and suffering. This is where the law tries to put a dollar value on the very human cost of an injury—the physical pain, the emotional trauma, and the loss of enjoyment of your life.

Of course, no amount of money can truly compensate you for being unable to pick up your kids or enjoy your favourite hobbies. What this compensation does, however, is provide a formal, legal acknowledgment of what you’ve been forced to endure.

In Canada, there’s a limit on how much can be awarded for pain and suffering. Back in 1978, the Supreme Court of Canada established a ‘cap’, which, adjusted for today’s inflation, sits at around $400,000. This cap is reserved only for the most catastrophic, life-destroying injuries, like quadriplegia or a severe brain injury.

This means that no matter how devastating the injury, the award for pain and suffering itself cannot go above this maximum figure. Your lawyer will determine a fair amount by comparing the specifics of your case to how courts have valued similar injuries in the past.

An Important Reality: The Statutory Deductible

For motor vehicle accident claims in Ontario, there’s another critical piece of the puzzle: the statutory deductible. This is a government-mandated amount that is automatically subtracted from any award for pain and suffering.

For 2024, that deductible is over $46,000. So, if your pain and suffering damages are valued at $100,000, you would only receive about $54,000 after the deductible is taken off. If your award is valued at less than the deductible, you get nothing at all for your pain and suffering. It’s a harsh reality that can dramatically change the outcome of a case. To get the full picture, you can read our comprehensive guide to Ontario’s pain and suffering threshold.

Putting all these pieces together—your financial losses, the value of your pain and suffering, and any applicable deductibles—is how the final compensation figure in an Ontario personal injury claim is built.

Answering Your Questions About Injury Lawsuits

Dealing with an injury is overwhelming on its own. When you add the legal system to the mix, it’s easy to feel lost and unsure of where to turn. We find that many people hesitate to even explore their legal options because of myths and questions about the process, the cost, and how long it all takes.

Let’s clear up some of that confusion. Here are straightforward answers to the most common questions we hear from our clients in Burlington, the GTA, and across Ontario.

How Long Do I Have to Start a Lawsuit in Ontario?

This is one of the most critical questions, because the clock starts ticking right away. Generally, Ontario’s Limitations Act gives you a two-year window from the date you discovered your injury to file a lawsuit. For most people, that discovery date is the day the accident happened.

But there’s a crucial exception for car accidents. You must give written notice that you intend to sue the at-fault driver within just 120 days of the crash.

These aren’t just suggestions; they are hard deadlines. Missing them can mean losing your right to compensation forever, no matter how strong your case is. That’s why it’s so vital to speak with a lawyer as soon as you can.

What Does It Cost to Hire a Personal Injury Lawyer?

The thought of legal bills is a major source of stress, and it stops too many people from getting the help they deserve. We want to put that worry to rest. Our firm operates on a contingency fee basis, which is the standard for personal injury law in Ontario.

What does that mean for you? Simple. You pay nothing upfront. There are no hourly rates or retainers. We only get paid if we win your case, and our fee is a pre-agreed percentage of the settlement or award we secure for you.

This approach levels the playing field. It ensures everyone has access to top-tier legal representation, regardless of their financial situation, so you can focus on what matters most: your recovery.

Is It Likely My Case Will Go to Court?

Most people imagine a tense courtroom drama when they think about a lawsuit. The reality? It’s far less dramatic and much more collaborative than you see on TV.

The truth is, it’s highly unlikely your case will ever go to trial. Over 95% of personal injury cases in Ontario are settled out of court. This happens through direct negotiation between lawyers or a structured settlement conference called a mediation. The entire system is built to encourage these resolutions because they save time, money, and stress for everyone involved. A trial is truly a last resort.

Can I Still Sue If I Was Partly at Fault?

Yes, absolutely. It’s a common misconception that if you share any blame for an accident, you can’t make a claim. Ontario law operates on a principle called ‘contributory negligence.’

This just means that fault can be shared. If a court finds you were, say, 20% responsible for the incident, your final compensation would simply be reduced by that 20%. You can still hold the other party accountable for their 80% share. Don’t let the fear of being partially at fault stop you from seeking the compensation you are entitled to.
