Best for: Families seeking malpractice trial experience
Among Paul Cahill's published results are an $11.5 million jury verdict for a child born with cerebral palsy and a successful trial against an emergency physician after a mother's death. Although these are medical negligence results, they aren't identified as surgical error outcomes. While his practice focuses heavily on malpractice, surgical errors are among the claims his site says he handles.

Best for: Families valuing appellate case experience
A medical malpractice success that Thomson Rogers LLP cites was upheld on appeal in Denman v. Radovanovic, 2024 ONCA 276. When you first meet, ask the lawyer to discuss that published result. Founded in 1935, the firm lists surgical errors on its site among the medical negligence claims it handles.

Founded in 1962, Gluckstein LLP lists a substantial team, with Charles E. Gluckstein as managing partner and Richard Halpern as senior counsel. Along with surgical errors, its site covers birth injury and medication errors. Although clients often praise clear updates and respectful treatment, some say intake responses were slow or they received little guidance after the firm declined their case.

To review your dates, the lawyer asks when you learned of the injury and its possible connection to your care. Once discovery occurs, Ontario's basic 2 years filing period begins. Along with the 15-year ultimate period, the lawyer must check any rules that affect your situation.
Examine the medical records
The lawyer then reviews what happened during surgery, along with what happened afterwards. Before providing records, ask which ones are needed. Ask how a medical opinion would examine causation (whether a failure caused the injury) alongside the standard of care (the care expected).
Start the claim
To start a lawsuit, you file a statement of claim setting out the allegations. An affidavit or certificate of merit isn't required to begin in Ontario. Even so, you must assess whether the claim has a medical basis while making sure you meet the applicable filing deadline.
Exchange supporting evidence
Under the court's rules, you must serve expert reports addressing the standard of care and causation. When discussing those reports with your lawyer, ask how the medical records support the allegations and where they make the claim harder to prove.
Discuss resolution or trial
Before deciding what to do, you'll hear from your lawyer about possible settlement and what a trial would involve. Trial and appeal results are published by some listed firms. Since those outcomes can't predict yours, ask what costs remain ahead before you make decisions about the claim.

If the claim fails under a contingency fee arrangement, there's no legal fee; otherwise, the lawyer receives a share of any money recovered. This arrangement is offered, according to their listed terms, by Bogoroch & Associates LLP, Bergel Magence LLP and Martin & Hillyer Associates. Case costs aren't included. You may face expenses for records and medical opinions, along with court fees. Who advances those costs, or pays them if the claim fails, isn't established by the firms' listed terms. Before proceeding, get a written answer and have the firm explain how it calculates the lawyer's share. Although a consultation is free, that doesn't mean the firm has agreed to fund your case.
A free consultation is offered by five of the six firms listed, according to their terms. Contingency arrangements are offered by three.

Questions to ask a lawyer
1What claims have you handled involving this operation and this kind of injury?
2If you took my file, who would work on it and review my records?
3To assess what happened, how would you obtain a medical opinion?
4Given my situation, which filing deadline do you think applies?
5What calculation do you use for your contingency fee?
6If the claim fails, who would cover the case costs?
7While you assess the claim, how would I hear from you?
8If you handled my file, which office would take it and where would we meet?
Choose around the operation and your dates
Begin with the operation involved. Although a firm that lists surgical errors is a starting point, ask whether it has handled claims about your operation and the resulting injury. If a firm publishes birth injury or emergency care results, those show medical negligence work. Experience with your particular surgical problem isn't established by those results.
Think about the meeting location. While Bergel Magence LLP has an Oakville office, Martin & Hillyer Associates is based in Burlington. Toronto offices are available at several other firms listed here. Although Gluckstein LLP lists an Ottawa office, it has a Toronto location too. Before booking, check where you'd meet and who would handle the file.
Ask how the medical review will work
Before supplying records, ask who would read your operative report and follow-up notes and what else they'd need.
Ask how the firm would obtain a medical opinion addressing whether the care you received caused your injury, alongside the care itself.
While the firm decides whether to take your claim, find out who would stay in touch. If it declines, ask what happens next.
If a published result seems relevant, ask the lawyer to explain it and how that case differs from yours.
On this list, five firms say a consultation is free. Before further assessment, ask whether you'd have to pay. Although the first meeting is free, you'll still need a separate discussion about what the eventual fee agreement covers. If the firm offers a contingency arrangement, find out how the lawyer's share is calculated, then ask who pays for records or medical opinions when no money is recovered.
If someone promises success, be wary. Although reviews offer some insight into communication, they aren't proof that your claim will succeed. Clients of several firms listed here have left comments describing slow responses or problems with intake. Before you sign, find out how you'd hear from the firm and from whom. If any fee terms aren't clear, ask for an explanation in plain language.
Questions people ask
What should I do first after a possible surgical error in Oakville?
Make a note of when surgery happened and what you learned afterwards. If you already have records, gather them, including your discharge instructions and follow-up notes. To check those dates, speak with an Ontario lawyer next. Before calling, you don't need answers to all the medical questions. When you have the consultation, find out what further records the lawyer needs and which medical opinions they'd seek.
How long do I have to start a surgical error claim in Ontario?
Once discovery occurs, Ontario's basic 2 years limitation period starts. To determine discovery, the test asks when you knew, or reasonably ought to have known, about the injury and a provider's contribution to it, as well as whether a lawsuit was appropriate. A 15-year ultimate limitation period applies as well. When calculating dates, don't use the operation alone. To find out which rules fit your situation, ask an Ontario lawyer.
What if my child was injured during surgery?
While a claimant is under 18 without a litigation guardian for the claim, Ontario's 2-year period doesn't run. In the lawsuit, that guardian acts on the child's behalf. If a claim arises while a minor has no litigation guardian, the 15-year ultimate period is also suspended, as addressed in Wong v. Lui, 2023 ONCA 272. To understand your child's dates, ask a lawyer how this applies.
Do I need a medical certificate before filing?
To start a medical malpractice claim in Ontario, you don't need an affidavit or certificate of merit. Even so, you must serve expert reports under the court's rules, addressing the standard of care and whether the failure caused the injury. When examining the care, those reports ask whether it fell short and whether that failure caused the injury. Before proceeding, find out how the lawyer would arrange that medical review.
Can I speak to a lawyer without paying for the first meeting?
Thomson Rogers LLP, Gluckstein LLP, Bogoroch & Associates LLP, Bergel Magence LLP and Martin & Hillyer Associates say they offer free consultations. Paul Cahill's listed terms don't confirm a free meeting. Ask before booking. You can use a free consultation to discuss the claim and fees, but it doesn't establish that later legal work or case expenses will be free.
If my claim fails, could I still owe case costs?
If a claim fails under a contingency arrangement, you don't owe a lawyer's fee. You still need to ask about case expenses. Along with court fees, getting records and medical opinions can cost money. If nothing is recovered, who pays those expenses isn't stated in the listed firms' terms. Before you sign, ask for a direct answer and make sure it's included in your written agreement.
How long will a surgical error lawsuit take?
For these firms, we don't have a supported estimate of case length. Before a case may move to settlement discussions or trial, assessing the claim involves reviewing records and getting medical opinions. To understand your file, ask what steps it needs. Because some reviews of the listed firms describe delays, also find out how you'd receive updates as your file moves along.
Is there a limit on compensation in Ontario?
For economic losses such as lost income or future care, Ontario has no statutory cap. A judge-made national cap, known as the trilogy cap, applies to non-pecuniary damages, which cover losses such as pain and suffering. What your claim is worth isn't established by either rule. To understand how these categories fit your injury, ask an Ontario lawyer to explain them alongside the records that support your claim.
What if a loved one died after surgery?
Make sure the lawyer knows the patient died. If you have hospital correspondence, bring it along with the surgery dates and records of follow-up care. Wrongful death claims are covered by several listed firms, including Thomson Rogers LLP and Martin & Hillyer Associates. Among Paul Cahill's published results is a trial involving a death after emergency care. To check who may bring a claim and which deadlines apply, ask an Ontario lawyer.
Do I need a lawyer with an office in Oakville?
Although meeting at an Oakville office may be easier, ask whether the lawyer has worked on surgical claims comparable to yours. In Oakville, Bergel Magence LLP has an office. While Martin & Hillyer Associates is about 18 km away in Burlington, other firms listed here have offices outside Oakville. Before choosing, check who would handle your records and where you'd meet.
