Choosing a malpractice lawyer in Hamilton

Start with the medical issue, rather than the rating. With a surgical injury, the discussion may differ from one about nursing home negligence. Nursing home negligence appears among Lamont Law's services. Ross & McBride - Personal Injury Lawyers publishes a result involving surgical malpractice. Ask how the lawyer would assess a claim like yours.

Make the first conversation useful

  1. Describe what happened

    Give the lawyer the treatment dates and explain when you first connected the injury to the care. Find out whether they need the chart or delivery notes to offer a view. They should specify which medical records they'll review.

  2. Ask who handles the file

    You'll want to know who's responsible for the file. Find out how you'll get updates. That lawyer's medical negligence work needs discussion too. Communication may come through in firm-wide reviews. Experience with your particular injury isn't something those reviews establish.

  3. Discuss medical proof

    You can start an Ontario claim without an affidavit or certificate of merit. Expert reports addressing the standard of care and causation must be served under the court's rules. Have the firm explain its approach to that assessment.

Get the fee arrangement in writing

You can book free consultations with Lamont Law, Ross & McBride - Personal Injury Lawyers, Martin & Hillyer Associates and DWA Law. At the meeting, find out what's covered for free. Ask whether you'll be charged for work after that discussion. You'll need to confirm Michael's Law Firm's consultation terms.

Contingency fees appear in Martin & Hillyer Associates' listing. Find out how the firm calculates its fee. Ask what triggers payment. Then ask which expenses you'd pay separately. You'll need to check each other firm's fee arrangement. Get written terms before you authorise any work. What you might owe if the claim fails should be clear.

Promises about outcomes are a warning sign. So is pressure to sign before fees are clear. Have the lawyer explain things plainly. Published recoveries can't forecast your outcome. That glowing settlement review could concern another practice area. Before committing, you need answers about who'll handle your claim and how the firm assesses medical evidence; keep asking if it won't explain.

Questions people ask

How long do I have to start a medical malpractice claim in Hamilton?
Ontario's basic two-year limitation period starts when the claim is discovered. Discovery depends on when you knew, or reasonably should have known, about the injury and the health care provider's contribution. Whether a lawsuit was appropriate also matters. The province's ultimate 15-year period also has exceptions that may apply. You can have an Ontario lawyer assess your case's dates.
Which firm on this list has a published medical malpractice result?
After a negligent surgical procedure, the patient had serious complications and permanent impairments. For that patient, the result published by Ross & McBride - Personal Injury Lawyers is $2,000,000. This list includes that published recovery from a malpractice claim. Ask about comparable claims the firm has handled, as well as that case. Another patient's possible recovery can't be established by that past result.
Can I get a free consultation with a Hamilton malpractice lawyer?
You can get a free consultation at Lamont Law or Ross & McBride - Personal Injury Lawyers. DWA Law and Burlington-based Martin & Hillyer Associates offer them too. Before booking, check Michael's Law Firm's consultation terms. Find out what the consultation covers, including any record review. Then ask what charges could follow if you proceed. The other firms' fee arrangements still need checking. Contingency fees are listed by Martin & Hillyer Associates.
Does Ontario require a medical expert's certificate before I can sue?
To start a medical malpractice claim in Ontario, you don't need an affidavit or certificate of merit. You'll still need medical proof. Expert reports must be served under the court's rules, with the reports addressing the standard of care and causation. Obtaining reports may involve costs; ask the lawyer about those and how they'd assess the standard of care and causation.
Are the filing rules different for an injured child?
For a claimant under 18 who has no litigation guardian for the claim, the two-year period doesn't run. The ultimate 15-year period is suspended too, if the claim arose while the claimant was a minor without a litigation guardian. The case addressing this is Wong v. Lui, 2023 ONCA 272. An Ontario lawyer can explain how guardianship and the dates affect your child's claim.
Is compensation capped in an Ontario medical malpractice claim?
Economic losses, such as lost income or future care, aren't subject to a statutory cap. For non-pecuniary damages, a national, judge-made trilogy cap applies. A published total recovery doesn't show how each part of your claim would be assessed. Different categories apply to these losses. You can discuss which losses may apply to your circumstances with an Ontario lawyer.
