    Many claims settle. Some go to a judge or jury.

Your deadline: 2 years from when you found outRead the Ontario law guide

Each step in more detail

  1. Check the limitation period

    When reviewing the timing, a lawyer considers when you discovered the injury and its connection to the care, and whether a lawsuit was appropriate. Once you discover the claim, Ontario's basic period runs for 2 years; a 15-year ultimate period also applies under the statute, subject to applicable rules.

  2. Review the care and injury

    As you explain what happened, go through the chart. When reviewing the care you received, the lawyer must consider whether an act or omission caused the injury or contributed to it. To complete that review, what other records or medical opinions does the lawyer need?

  3. Decide whether to start the claim

    Before starting a claim, discuss the applicable limitation period with the lawyer if they've agreed to proceed. Although Ontario lets you begin without an affidavit or certificate of merit, you'll need medical evidence as your case moves forward.

  4. Develop the medical evidence

    To address the claim, expert reports cover the standard of care (the care expected) and causation (the connection to the injury). You'll need to serve them under the court's rules. Where the medical answers are still uncertain, ask your lawyer about that and what the opinions do support.

  5. Assess losses and possible resolution

    To assess the claim's losses, the lawyer considers lost income or future care when they apply. Although Ontario has no statutory cap on economic losses, non-pecuniary damages, such as pain and suffering, are limited by a judge-made national cap. When reading published awards, don't use them to predict your own result.

What a malpractice lawyer costs in Mississauga

  1. The first callOften free. Ask before you book.
  2. A written agreementThe share the lawyer takes, set out before work starts.
  3. If you recover moneyThe agreed share and the case costs come out of it.
  4. If the claim failsNo legal fee on a contingency agreement. Ask about costs.
According to Sommers Roth & Elmaleh and Bogoroch & Associates LLP, you'll pay their legal fees through a contingency arrangement. If the claim fails, the lawyer receives no legal fees; a recovery gives them a share of it. You'll also need to cover case costs separately from legal fees, including records and medical opinions, as well as the court fees. The firms' stated arrangements don't say who usually pays those bills at the start, nor do they make clear who must ultimately cover them. Who has to cover those bills if there's no recovery? Ask for the fee calculation in writing before signing, including an explanation of who must pay the costs. Because Paul Cahill's consultation and fee arrangements haven't been confirmed, you'll need to ask him what they are.

According to two of the three firms listed here, you can get a free consultation and contingency fees.

What to bring to your first call

  • A short timeline you've written of the treatment and when you noticed the injury
  • Whatever hospital charts and discharge papers you have already
  • If you're concerned about a birth injury, delivery notes
  • Who was involved: the hospital's name and the health care providers' names
  • Relevant test results, along with your medication records
  • Information about lost income or care expenses, with bills
  • Letters you've received from the hospital or insurer
  • If you have photos relating to the injury, those too

Questions to ask a lawyer

  1. 1When the care was like mine, how many claims have you handled?
  2. 2Who'll I regularly speak with among those working on my file?
  3. 3For my claim, when does Ontario's limitation period end?
  4. 4To assess my case, what do you need for records and medical opinions?
  5. 5Does the first consultation cost anything? What's covered in it?
  6. 6What's your method for calculating the contingency fee?
  7. 7If there's no recovery, who pays the case expenses?
  8. 8When there's progress or a decision, how will you update me?

Choose around the care that went wrong

Start with what went wrong in the hospital, rather than choosing a firm for its reputation alone. If a diagnosis was missed, you'll have different questions about the chart than if an injury happened during delivery. After explaining what happened and what changed afterwards, ask the lawyer whether they've handled claims about that kind of care. Before they decide whether to investigate your claim further, what would the lawyer need to see?

We didn't put every firm here for the same reason. When you compare Paul Cahill's published birth injury and emergency room trial results with Sommers Roth & Elmaleh's substantial obstetric results, remember that Sommers Roth & Elmaleh handles only medical malpractice. Hospital care claims appear on Bogoroch & Associates LLP's site, though the firm also handles a broader range of injury cases. Don't treat a published recovery as your claim's value; use it to ask about the lawyer's experience instead.

Ask how your file would be handled

  • Before you go ahead, find out who reviews your chart and who'll be your regular contact among the lawyers. How will you hear from the firm when there's little to report?
  • Tell the firm if you find travel difficult. Ask Paul Cahill and Bogoroch & Associates LLP how you'd meet and send documents, since their offices are in Toronto, not Mississauga.
  • If your claim needs medical opinions, how would the lawyer get them? You can start an Ontario claim without a certificate of merit. The court rules still require you to serve expert reports on the standard of care and causation as the case proceeds.

Read the fee agreement before signing

You can get a free consultation according to Sommers Roth & Elmaleh and Bogoroch & Associates LLP, which also say they offer contingency fees. Even though you can discuss the claim without paying for the consultation, that doesn't mean the firm has agreed to take your case. If the claim fails, you don't owe legal fees under a contingency arrangement; the lawyer receives a share when there's a recovery. What about the expenses of the case?

If someone points to another client's award and promises you could recover the same, that's a reason to be wary of them. Before going ahead, find out the cost of records and medical opinions, including who would have to pay those bills if your claim doesn't succeed. Do you still have questions? Don't sign the agreement until you've asked for an explanation in writing. This is general information, not legal advice for your situation.

Questions people ask

How long do I have to start a hospital negligence claim in Mississauga?
Once you discover the claim, Ontario's basic limitation period runs for 2 years. Discovery means you knew, or reasonably ought to have known, that a provider's act or omission was connected to the injury, and you also knew that bringing a lawsuit was appropriate. Under the Limitations Act, there's also a 15-year ultimate period. With your dates in hand, ask an Ontario lawyer which rules apply to your claim.
Can I get a free consultation with a lawyer on this list?
Sommers Roth & Elmaleh and Bogoroch & Associates LLP say they offer free consultations. Paul Cahill's consultation arrangements remain unconfirmed; ask before you book. A free consultation lets you discuss your concern without a consultation charge. It doesn't mean the lawyer has accepted your claim, and it doesn't make later work free.
Will I have to pay legal fees if the claim fails?
According to Sommers Roth & Elmaleh and Bogoroch & Associates LLP, they offer contingency fees, meaning no legal fees if the claim fails and a share for the lawyer if there's a recovery. You'll face case expenses separately. If there's no recovery, who pays for the records and medical opinions? Before signing, read what the agreement says about those costs.
What medical evidence does an Ontario hospital negligence claim need?
To start a claim in Ontario, you don't need an affidavit or certificate of merit. As the case proceeds, though, court rules require you to serve expert reports addressing the standard of care and causation. When giving those opinions, they consider the care expected and whether the alleged failure caused the injury. Before going further, ask your lawyer which medical questions remain unanswered and what the chart shows.
What should I do before calling a Mississauga hospital negligence lawyer?
Before calling, note the treatment dates and when you first noticed something wrong, then pull together the records you already have, including any relevant hospital letters. While you're waiting for a complete chart, you can still ask about the limitation period. After assessing the timing, an Ontario lawyer can tell you which documents would help them look into the care you received.
Are the time limits different for an injured child?
Until a person turns 18, the 2-year period doesn't run if they have no litigation guardian for the claim. If the claimant was a minor without a litigation guardian when the claim arose, the 15-year ultimate period is also suspended, as addressed in Wong v. Lui, 2023 ONCA 272. To understand what those conditions mean for your child's claim, speak with an Ontario lawyer.
Can a lawyer review the case if my loved one died after hospital treatment?
Among Paul Cahill's published results is a successful trial verdict involving an emergency room physician and a mother's death. Among the claims Bogoroch & Associates LLP lists is wrongful death. If you ask either firm for a review, they can consider the treatment and its connection to the death. Before your family proceeds, an Ontario lawyer must explain who may bring a claim and which limitation rules apply.
How long will a hospital negligence claim take?
You won't find a substantiated estimate of case duration for these firms. Even if you start before the limitation period expires, finishing is another matter, because medical evidence must address the care and its connection to the injury, and Ontario's court rules require expert reports to be served. If someone promises a finish date, don't rely on it; ask your lawyer what has to happen next and how you'll hear about progress.
Is there a cap on compensation in Ontario?
For economic losses such as lost income or future care, Ontario sets no statutory cap. Non-pecuniary damages, which include pain and suffering, do face a judge-made national cap. Because those losses fall into different categories, you can't use the published birth injury awards on this list as a guide to your claim's value. To find out which losses may apply, ask an Ontario lawyer.
