Paul Cahill's published results include an $11.5 million jury verdict for a child born with cerebral palsy and a successful trial against an emergency room physician following a mother's death. Medical negligence accounts for 80% of his practice, with hospital negligence and medication errors among the areas he handles. That focus and those trial results support his position here.

Harte Law has published cases where more than one patient was hurt. An anaesthetist's inadequate infection control prompted a class action; when the negligence decision was appealed, it stood, and the court approved a damages settlement. Another case concerned hepatitis B infections linked to the EEG procedures a neurologist performed.

When describing what happened, explain when you learned that the care might have caused harm. Discovery starts Ontario's basic 2-year period; treatment doesn't automatically start that clock. To work out which dates affect your claim, the lawyer can assess them.
Review the hospital records
When assessing your claim, the lawyer may review the hospital chart and disputed treatment records, including notes from delivery. Find out which records aren't there. To assess the care and whether it's connected to the injury, ask if the lawyer needs a medical opinion.
Start the claim
If you're starting a claim in Ontario, you don't need an affidavit or certificate of merit. Before the lawyer files, they should check the applicable limitation period and explain what the statement of claim says about the allegations.
Develop the medical evidence
Under the court's rules, expert reports about the standard of care and causation must, in practice, be served. To address those issues, the reports examine what care was expected and whether departing from it caused or contributed to the injury.
Consider resolution or trial
You'll find published settlements and trial verdicts from the listed firms. Yours can't be predicted from those results. Before agreeing to the lawyer's proposed next step, ask which evidence supports it and whether case expenses could affect your choices.

If your claim recovers money, Harte Law and Bogoroch & Associates LLP say the lawyer takes a share; under their contingency terms, a failed claim means no lawyer's fee. That excludes case expenses. You may still have to pay for hospital records and medical opinions, as well as court fees. Neither firm states who pays those expenses if there's no recovery, and you won't find who advances the money in their stated terms. Ask for the fee calculation in writing before you sign, with an explanation of who will have to pay the expenses as well. Because Paul Cahill's consultation and payment arrangements aren't stated, you'll have to check those terms with him directly.
According to Two of the three listed firms, you can get a free consultation and pay through contingency.

Questions to ask a lawyer
1Does the hospital care I received resemble care involved in claims you've handled?
2If I need updates, who would talk with me and handle my file?
3To assess my claim, what records or medical opinions would you need?
4Given the dates in my case, how does Ontario's limitation period apply?
5If we recover money, how would you work out your fee?
6If my claim fails, who would pay the case expenses?
7What's included if the first consultation is free?
8If we meet, must I travel from Markham?
Choose around the care that went wrong
Which part of your care concerns you? If delivery was delayed, that may be your concern; you might instead be worried about an infection after treatment or a medication error. Before discussing what the lawyer would need to assess your claim, ask if they've handled one like it. If a lawyer publishes a birth injury verdict, you know they've handled that dispute, but it doesn't establish the merit of a different hospital claim.
You won't find these offices in Markham. You'd visit Harte Law in Richmond Hill, or travel to Toronto for Paul Cahill or Bogoroch & Associates LLP. Could you discuss your claim by phone first? Ask whether later meetings would require travel too, before you book a visit to the office.
Ask how your file would be assessed
Once I've requested the hospital records you need, who would review my chart?
To assess the care or determine what caused the injury, would you need a medical opinion?
If I needed an update on my file, would I speak to the person handling it?
Without sharing another client's private information, could you describe a similar case you've handled?
Notice how reviews describe communication over time. Ratings can't predict what'll happen. Although Paul Cahill's feedback praises clear explanations, it includes a communication complaint; Bogoroch & Associates LLP's reviews also include a report that a follow-up was missed. If a call goes unanswered or a lawyer's away, ask each firm who steps in and how you'd hear back.
Get the payment terms in writing
You can consult Harte Law and Bogoroch & Associates LLP for free, they say, and their work uses contingency fees. At that free consultation, you can discuss the claim without paying for the discussion. Later expenses aren't necessarily covered by that offer, though. Even if the contingency fee depends on recovering money from your claim, ask who pays the court fees and how much the medical opinions would cost.
If someone promises a result, be wary, especially when they're pushing you to sign an agreement whose terms you don't understand. If you don't understand a term, ask for an explanation, especially about expenses when a claim fails. This page gives general information, not legal advice. Speak with an Ontario lawyer to find out how these rules apply to your circumstances.
Questions people ask
How long do I have to start a hospital negligence claim in Markham?
When you discover a claim, Ontario's basic 2-year limitation period starts. You've discovered it when you knew, or reasonably ought to have known, that you'd been injured and a health care provider's act or omission had contributed to that injury. You must also have known a lawsuit was appropriate. There's also a 15-year ultimate period, though applicable rules affect it. To check your dates, ask an Ontario lawyer.
Do I need a medical report before starting a claim?
To start an Ontario claim, you don't have to provide an affidavit or certificate of merit. Although that isn't required, medical evidence still matters: expert reports on the expected standard of care and causation must, in practice, be served under the court's rules. Before paying for a medical opinion, ask when the lawyer would need one and who would cover its cost.
Can I speak to one of these firms without paying for the consultation?
Harte Law and Bogoroch & Associates LLP say their consultations are free. Paul Cahill's consultation terms aren't stated; check before booking. A free first discussion doesn't answer who pays for later legal work or medical reports. Have the firm explain those terms before you agree to proceed.
What happens to legal fees if my claim fails?
If your claim fails under a contingency arrangement, there's no lawyer's fee; if you recover money, the lawyer takes a share of it. According to Harte Law and Bogoroch & Associates LLP, you can use this arrangement. That excludes expenses. If your claim recovers nothing, find out who must pay for records and medical opinions.
Are the deadlines different for a child's claim?
Yes. Until someone turns 18, the 2-year period doesn't run if they have no litigation guardian for the claim. If a claim arises in those circumstances, the 15-year ultimate period is suspended too, as addressed in Wong v. Lui, 2023 ONCA 272. Before assuming you can wait, ask an Ontario lawyer to explain how those rules affect the claim.
What does a hospital negligence case need to establish?
To assess the medical care, the review must address the standard of care, meaning what was expected in those circumstances. Whether the care caused or contributed to the injury must also be addressed; that's what causation means. Reports from experts on both issues are, in practice, part of the process. When reviewing the hospital chart, ask which details support or weaken each issue.
How long will a hospital negligence claim take?
You won't find a fixed overall duration in Ontario's rules. Although these firms report settlements and trial results, you can't use the time their past cases took as a timetable for yours. Before estimating how your claim might progress, ask which work the lawyer still needs to do to assess it and what could slow it down.
Which listed firms handle claims involving a loved one's death?
If you're considering a wrongful death claim, Harte Law and Bogoroch & Associates LLP list that work among their practice areas. After a mother's death following emergency room negligence, Paul Cahill obtained a successful trial result that he's published. Although that's relevant work, it doesn't show whether your family has a claim. To establish who may bring a claim and which deadline applies, ask an Ontario lawyer.
Is there a cap on compensation in Ontario?
If you're claiming economic losses, such as lost income or future care costs, Ontario has no statutory cap. A national judge-made limit called the trilogy cap applies to non-pecuniary damages, which include compensation for pain and suffering. You can't work out a claim's value from these rules. To assess the losses you're claiming, ask a lawyer which evidence supports them.
Do I have to hire a lawyer with an office in Markham?
Although their offices are nearby, none is in Markham. You'd travel to Richmond Hill for Harte Law, 10 km away; the other listed offices are in Toronto, 26 km away. Before you choose, find out how you'd meet. If you ask about travel and reaching the person handling your file, you deserve a clear answer about both.
