When discussing the treatment dates, explain when you discovered the possible claim. You generally have 2 years from discovery under Ontario's basic limitation period, with an ultimate period of 15 years. Before waiting for further records, ask a lawyer how those rules apply to you.
Review the medical history
When you bring your chart or other records you have, include your account of what happened. To assess the care and whether it caused or contributed to the injury, ask what further records and medical opinions the lawyer needs.
Start the claim
Before starting the claim within the applicable limitation period, discuss it with the lawyer who agrees to proceed. Although Ontario doesn't require an affidavit or certificate of merit at the start, you still need to address the medical issues.
Obtain expert reports
To address the standard of care and causation, expert reports examine the care and its connection to the injury. The court's rules require those reports to be served in practice. How would the lawyer get those reports?
Assess the claimed losses
If you're claiming lost income or future care needs, ask how the claim would support them. Although Ontario has no statutory cap on economic losses, non-pecuniary damages, such as pain and suffering, face a judge-made national cap. Ask what that cap means for your claim.

Contingency fees are available, according to Reyes Tam Law. Fee arrangements aren't confirmed by the other listed firms. If the claim fails under a contingency arrangement, there's no lawyer's fee; if you recover money, the lawyer takes a share. You pay case expenses separately, which can include charges for medical records and medical opinions, along with court fees. Because the listed firms don't say who advances those expenses or ultimately pays them, you'll need to ask them directly. Get the fee calculation in writing before you sign. If the claim fails or you choose to stop, ask what you could still owe.
Among the three listed firms, only Reyes Tam Law says both free consultations and contingency fees are available to its clients.

Choosing a lawyer for a Newmarket malpractice claim
Rather than starting with the firm's general reputation, focus on what happened during your medical care. When you explain what happened and when you first suspected the care caused harm, ask if the lawyer has handled claims about that treatment. Medical malpractice sits within broader practices at each of the listed firms. Malpractice results don't appear on any firm's site. Instead of accepting a general statement about experience, ask about files involving care like yours.
Who'll actually work on your file is worth finding out. Even if someone's name appears on the firm's website, that doesn't tell you who'll examine your chart or answer calls. When you ask how the lawyer would get medical opinions, also ask what they need to assess causation (whether the care caused or contributed to the injury). To start a claim in Ontario, you don't need a certificate of merit. You still have to serve expert reports on care standards and causation under the court's rules.
Has the lawyer handled claims about your treatment or injury? Unrelated legal-work reviews won't tell you that.
Before agreeing to fees, get written terms stating who pays case expenses if nothing is recovered.
If travel is required rather than remote meetings, find out. None of the listed offices is in Newmarket.
If a consultation is free, you can use it to discuss a possible claim. A full medical review isn't necessarily part of it. Although Reyes Tam Law says it offers free consultations and contingency fees, neither arrangement is confirmed for the other listed firms. If you recover money under a contingency arrangement, the lawyer takes a share; if the claim fails, there's no lawyer's fee to pay. Get separate case costs explained clearly before you agree.
If someone promises results or pushes you to sign terms you don't understand, be wary. Get any unclear terms explained in writing by the lawyer. Because Ontario's limitation rules distinguish whether a litigation guardian has been appointed, tell the lawyer about that detail if the patient is a child. This isn't legal advice, just general information. Ask an Ontario lawyer to assess your family's circumstances.
Questions people ask
How long do I have to start a malpractice claim in Newmarket?
You generally have 2 years from discovery under Ontario's basic limitation period. The treatment date doesn't necessarily start that clock. Discovery means you know, or reasonably should know, about your injury and how the provider contributed to it, and you also know whether a lawsuit was appropriate. There's also a 15-year ultimate period to consider. Ask an Ontario lawyer to work out the deadline for your circumstances.
Do these firms offer free consultations?
Although Reyes Tam Law says its consultation is free, neither Hummingbird Lawyers LLP nor Blackburn Lawyers has confirmed a free consultation. Check before booking. Before asking whether a medical-record review or medical opinion costs extra, find out what the meeting includes and whether you'll pay for it.
Can I hire a malpractice lawyer on contingency?
Although contingency fees are confirmed by Reyes Tam Law, the other listed firms don't confirm that they offer this arrangement. If you recover money, the lawyer receives a share. Under a contingency arrangement, you won't pay a lawyer's fee if the claim fails. Before signing, get written terms and ask about case expenses, including medical opinions, because those costs are separate from the lawyer's fee.
What does a medical malpractice claim need?
When assessing the medical issues, you must address the standard of care and causation: whether the provider's care caused or contributed to the injury. To begin a claim in Ontario, you don't need an affidavit or certificate of merit. In practice, the court's rules require you to serve expert reports dealing with those issues. Which records would the lawyer need to assess those questions?
Are the deadlines different for a child's claim?
Yes. Until the claimant turns 18, the 2-year period doesn't run if there's no litigation guardian for the claim. If a claim arises while the claimant is a minor without a litigation guardian, the 15-year ultimate period is suspended too. This rule is addressed in Wong v. Lui, 2023 ONCA 272. Have an Ontario lawyer look at your child's circumstances.
How long will a malpractice claim take?
You won't find a malpractice-claim timetable published by any of the listed firms. Rather than telling you how long a case takes, the 2-year limitation period sets a filing rule tied to discovery. Once the initial record review is done, ask what comes next and how the lawyer would get expert reports. Ask, too, how the lawyer will keep you updated.
What should I do if a loved one died after medical care?
After writing down the treatment dates, gather the records you already have, along with hospital correspondence. Wrongful death appears on the sites of both Reyes Tam Law and Blackburn Lawyers. To learn who can bring a claim and which deadlines apply, ask an Ontario lawyer. Even if wrongful death appears in a firm's practice listing, that doesn't prove it's handled a case like yours.
Do I need a lawyer with an office in Newmarket?
None of the listed firms has offices in Newmarket. From Newmarket, it's 24 km to Reyes Tam Law's Markham office; Hummingbird Lawyers LLP's Vaughan office is 25 km away. You'll find Blackburn Lawyers 18 km away in Richmond Hill. Before you hire, find out whether meetings and exchanging documents would require travel and how you'd handle them.
Is there a limit on the damages I can claim?
If you're claiming economic losses, such as lost income or future care, Ontario has no statutory cap. A judge-made national cap does apply to non-pecuniary damages, which include pain and suffering. You can't work out your claim's worth from that distinction alone. To understand which losses may apply and what records would support them, ask an Ontario lawyer.
