Check the dates first. When you discover the claim, including knowing that a lawsuit was appropriate, Ontario's basic limitation period of 2 years starts. If a minor has no litigation guardian, the clock doesn't run. Ask an Ontario lawyer to explain how these rules affect your claim.
Review the treatment history
For the lawyer's review, gather the records you already have along with your treatment dates. When you write down what you believe went wrong, include when you learned about it. With your account, the lawyer can discuss the injury and how the provider was involved.
Start the claim
Before you sue a doctor, nurse or hospital, Ontario doesn't require notice. To start a claim, you don't need an affidavit or certificate of merit either. Because the filing deadline still applies, ask the lawyer when you have to start your claim.
Obtain medical opinions
When a case proceeds, the court's rules require service of expert reports. The care expected of the provider (the standard of care) is covered in these reports. To address causation, they examine whether the act or omission caused or contributed to the injury.
Assess the claimed losses
If you've lost income or need future care, discuss it. For those economic losses, Ontario sets no statutory cap. Although a national judge-made cap limits non-pecuniary damages, such as compensation for pain and suffering, the rest of the claim isn't capped by it.

If the claim failsNo legal fee on a contingency agreement. Ask about costs.
If you recover money, several firms on this Toronto list take a share as their contingency fee; if the claim fails, there's no legal fee. Case costs come separately. You may still face charges for medical records and medical opinions, as well as court fees. Who usually advances those costs, and who pays if the claim fails, isn't explained in the firms' listed fee information. Don't sign without asking. Ask how much the lawyer will take and which expenses you'll have to pay, including when they're due. Even if the consultation is free, it doesn't settle the terms for taking your case.
Seven firms out of the eight say their consultations are free. Five offer contingency fees, they say.

Choosing a Toronto malpractice lawyer
Let the medical issue guide you, not the firm's overall injury practice. If you're comparing birth injury with delayed diagnosis, the claims may need different medical evidence. Before choosing the proposed lawyer, ask whether they've handled that issue and what they did in the case. A published result gives you a concrete talking point, not a forecast of your family's result.
Make the first conversation useful
1
Describe what happened
Put the dates you know into a short timeline. When explaining the treatment you question, say when you first suspected it had caused harm. Before gathering the chart or delivery notes, ask which records the lawyer wants to review.
2
Identify the person responsible
Before the firm accepts your claim, find out who will assess it and who would handle it. How will updates reach you? If the firm has several offices, find out whether your file will stay with that lawyer as you confirm where you'll meet.
3
Discuss the medical assessment
In Ontario, you can start a claim without an affidavit or certificate of merit. In practice, the court's rules require parties to serve expert reports on the standard of care and causation. Ask how the firm handles those reports, including who pays for them.
Get fees explained before agreeing
Several listed firms will consult with you for free. Before assuming ongoing work is included, ask what the free meeting actually covers. If a firm offers contingency fees, get its agreement in writing after asking how payment depends on the result. Ask the lawyer to explain any percentage before going through taxes and expenses separately, including what you might owe if your claim doesn't succeed. Both fee arrangements remain unconfirmed for Paul Cahill - Medical Malpractice Lawyer.
If someone promises a particular payout, that's a warning sign. If fees aren't explained clearly or nobody tells you who's responsible for follow-up, pause before going further. Use reviews to shape your questions about communication. Although reviews don't establish how a firm handled a medically similar claim, several firms here have positive feedback mixed with complaints about intake or delays. Ask about them directly.
Questions people ask
How long do I have to start a medical malpractice claim in Toronto?
Ontario's basic limitation period starts at discovery, lasting two years. Discovery means you know, or reasonably should know, about your injury and the provider's part in it. Whether a lawsuit was appropriate also matters to that test. Your treatment date doesn't automatically set the clock running. A 15-year ultimate period also applies. Ask an Ontario lawyer to work through how those rules apply to your circumstances.
Does the deadline work differently for a child's birth injury claim?
Yes. If the claimant is under 18 and has no litigation guardian for the claim, the two-year clock doesn't run. Wong v. Lui, 2023 ONCA 272 addresses how the 15-year ultimate period is also suspended for a claim arising while the claimant is a minor without a litigation guardian. Ask an Ontario lawyer how this rule applies to your child's claim.
Do I need a medical expert's certificate before starting a claim?
In Ontario, you can start a medical malpractice claim without an affidavit or certificate of merit. In practice, the court's rules require parties to serve expert reports on the standard of care and causation. During the consultation, have the lawyer explain how they assess the chart and obtain those reports. Have the related costs explained, too, including how they'd be handled.
Which firms on this list offer free consultations and contingency fees?
You can get both from Neinstein Personal Injury Lawyers, Howie, Sacks & Henry LLP, Bergel Magence LLP ⚖️ Personal Injury Lawyers, Bogoroch & Associates LLP and Diamond & Diamond Lawyers LLP. You can get free consultations from Thomson Rogers LLP and Gluckstein Lawyers, though their contingency arrangements aren't confirmed. Both arrangements remain unconfirmed for Paul Cahill - Medical Malpractice Lawyer. Before agreeing to anything, have the firm explain its terms.
Is there a cap on medical malpractice compensation in Ontario?
You won't find a statutory cap in Ontario for economic losses such as lost income or future care. The judge-made trilogy cap applies nationally when assessing non-pecuniary damages. When discussing a published multimillion-dollar result, keep those categories in mind, because the total doesn't show how each was assessed. You're reading general information, not legal advice. Ask an Ontario lawyer how these rules apply to the losses you're claiming.
Do I have to notify the doctor or hospital before starting a claim?
Before you sue a doctor, nurse or hospital for medical malpractice, Ontario doesn't require you to give notice. That means you can start the lawsuit without first completing a separate step to notify them. You're still within the limitation period's rules. Because this is general information rather than legal advice, ask an Ontario lawyer to explain what you need to do in your circumstances.
Which firms on this list handle nursing home claims?
The practice areas listed by Howie, Sacks & Henry LLP and Bogoroch & Associates LLP both include nursing home neglect. If you're looking for a starting point for a call, both say their consultations are free and they offer contingency fees. Has the lawyer handled a care failure like the one that concerns your family? Ask which records they'd need to look through.
Can I contact these firms about a missed diagnosis or surgical error?
The practice areas of Paul Cahill, Thomson Rogers LLP and Gluckstein Lawyers include both misdiagnosis and surgical error. They're also listed by Bergel Magence LLP, Bogoroch & Associates LLP and Diamond & Diamond Lawyers LLP. It doesn't mean they've assessed your particular claim. Before asking whether the lawyer will review your records, explain the treatment you received and what you found out later.
What if a firm's consultation or contingency terms aren't listed?
Contact the firm yourself. Whether Paul Cahill's consultation is free or fees are contingent isn't confirmed in the entry. Although Thomson Rogers LLP and Gluckstein Lawyers confirm free consultations, their entries leave contingency terms unconfirmed. If those details are missing, it doesn't mean the first call costs money or that the firm won't accept a contingency arrangement. Before agreeing to representation, ask the firm to explain its terms.
