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

Each step in more detail

  1. Review the events and dates

    Write down what happened and bring the prescription details. With that information, the lawyer can assess when you discovered the injury and its possible connection to the provider. To work out Ontario's limitation period, the lawyer needs those facts.

  2. Assess the medical issues

    What do the chart and medication records show? Medical opinions look at whether the care fell below the expected standard, then whether that failure caused or contributed to the injury. How does the firm assess those questions?

  3. Start the claim

    You generally have to start an Ontario claim within 2 years of discovery. To begin, you don't need an affidavit or certificate of merit. Rather than assume the clock starts on the prescription date, a lawyer should check the deadline that applies to you.

  4. Serve expert reports

    When a claim proceeds, the court's rules require expert reports on the standard of care and causation to be served in practice. Those reports examine the alleged medication mistake and whether it's connected to the harm being claimed.

  5. Address the claimed losses

    If you've lost income or need future care, a claim may include those costs. No Ontario statute puts a cap on economic losses. For non-pecuniary damages, including compensation for pain and suffering, the national judge-made trilogy cap sets a limit.

What a malpractice lawyer costs in Ottawa

  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.
If your claim fails, LMS says its contingency arrangement means no legal fee; otherwise, the lawyer takes a share of a recovery. Although Gluckstein LLP offers a free consultation, you won't find its contingency terms listed. You can't infer Nelligan Law's terms from either firm's offer. You'll have separate case expenses. When you ask about charges for records and medical opinions, check court fees too. If there's no recovery, who owes that money, and who advances it? The firm won't necessarily pay every expense. Ask for a written explanation of the recovery share, including any deductions, before you sign.

According to the listed firms, two of the three offer a free consultation. Contingency work is also offered, one says.

What to bring to your first call

  • If you have them, your prescription and the medication packaging
  • Discharge instructions, together with your chart and pharmacy records
  • When the prescription was issued, when you suspect the error happened, plus when symptoms began
  • Which providers and pharmacies were involved, by name
  • What happened, set out in a brief written timeline
  • Records of income the injury cost you, along with bills
  • Any hospital or insurer letters you've received
  • Photos showing anything related to the medication or injury

Questions to ask a lawyer

  1. 1When handling this kind of medication error, how many claims have you worked on?
  2. 2Who'll work on my file, and will that person assess my case?
  3. 3Given my circumstances, what's the deadline?
  4. 4To assess my claim, what medical opinions would you need?
  5. 5Is the first consultation you offer free?
  6. 6If there's a recovery, how will you work out your legal fee?
  7. 7Who pays the case expenses if the claim fails?
  8. 8Who should I contact, and how will I get updates?

Choosing an Ottawa medication error lawyer

Rather than the ranking, start with the medication. When you explain what was prescribed and what you received, include when the injury became apparent. If a firm lists medication errors, that's a starting point. But ask about the lawyer who would actually assess your file. Each firm has an office in Ottawa.

Make the first conversation useful

  1. Ask about a comparable claim

    Use your own words to describe the suspected mistake. When you ask about experience, has the lawyer handled that kind of prescription or dispensing claim? How would they examine the chart, too? Even if a firm handles personal injury, that doesn't tell you how often a particular lawyer takes medication cases.

  2. Find out who stays in touch

    Ask who'll work on your file, then find out whom to contact when you need an update. Although Gluckstein LLP's reviews praise explanations, some clients also describe delays during intake. Because Nelligan Law's communication reviews include other practice areas, you'll need to ask about the team handling medical claims.

  3. Discuss medical opinions early

    You can start an Ontario claim without an affidavit or certificate of merit. In practice, though, you'll still need expert reports. Those reports must address the standard of care (the care expected of the provider), as well as causation: whether the mistake caused or contributed to the injury. How will the firm get those opinions for you?

Don't give reviews too much weight. None of these firms has a listed, published medication error result. Although reviews show how clients felt about communication, they can't tell you what happened in a prescription claim. When you ask the lawyer about relevant experience, don't expect them to share information that belongs to another client and is private.

Even if the consultation is free, the firm might not take your case. You can get one at Gluckstein LLP or LMS; LMS also says it works on contingency. Ask to see the proposed fee arrangement in writing. If the claim fails, it should say who pays for records and medical opinions. If anyone promises an outcome or presses you to sign before explaining costs, be wary. If anything's unclear, ask them to explain.

Questions people ask

How long do I have to start a medication error claim in Ottawa?
You generally have 2 years from discovery under Ontario's basic limitation period. Taking the medication doesn't automatically start the clock that day. You discover a claim when you know, or reasonably should know, about the injury and the provider's contribution, and whether a lawsuit was appropriate. There's also a 15-year ultimate period under the Limitations Act, 2002. Have an Ontario lawyer check your dates without delay.
Do I need a medical report before I can start a claim?
To start a medical malpractice claim in Ontario, you don't need an affidavit or certificate of merit. You'll still need medical opinions, though. When a claim proceeds, the court's rules require expert reports on the standard of care and causation to be served in practice. When you ask which records the lawyer needs, also ask how they'll check whether the medication mistake caused or contributed to your injury.
Can I speak to an Ottawa lawyer without paying for the first call?
Gluckstein LLP and LMS say they offer free consultations. Nelligan Law's consultation terms aren't listed; ask before booking. A free conversation doesn't mean the firm has agreed to represent you, or that later work is free. Use that first call to explain the suspected error and discuss your dates. Ask about the proposed fee arrangement too.
Will I owe legal fees if my claim fails?
If the claim fails under a contingency arrangement, the lawyer gets no legal fee; otherwise, they receive a share of a recovery. You can get this arrangement, LMS says. Expenses aren't included. If there's no recovery, who pays for records and medical opinions? Ask for those terms in writing. The listed firms don't necessarily all use the same fee arrangement, so don't assume they do.
How long will a medication error claim take?
You can't rely on one timetable for all the claims this list describes. To assess a claim, a lawyer examines records and medical questions, and Ontario's court rules also require expert reports to be served. When you ask what work your file needs, find out how the lawyer will update you. Don't confuse the deadline for filing with the time it takes to resolve your case.
What should I do before contacting a firm?
Write a short timeline and gather the prescription details. When you set it out, include when symptoms began and when you learned of a possible mistake. If you have chart or pharmacy records, bring them. If some records are missing, ask the firm what it needs from you. Don't wait for a complete file before calling; discuss the limitation period on that first call.
Are the deadlines different if my child was injured?
Yes, they can. If a claimant is under 18 and has no litigation guardian for the claim, Ontario's 2-year period doesn't run. For a claim arising while the claimant is a minor without a litigation guardian, the 15-year ultimate period is also suspended, as addressed in Wong v. Lui, 2023 ONCA 272. How do those conditions apply? Ask an Ontario lawyer.
Who can I contact if a loved one died after a medication error?
Alongside medication errors, you'll find wrongful death claims listed on both Gluckstein LLP and LMS sites. Can they assess whether the prescription was connected to your loved one's death? That's worth asking. Don't take this general information as legal advice. When you speak with an Ontario lawyer, they can explain who may bring a claim in your circumstances and the deadlines that apply.
Is compensation capped in Ontario medication error cases?
If you've lost income or face future care costs, Ontario has no statutory cap on those economic losses. But non-pecuniary damages have a limit. For those damages, including pain and suffering, a national judge-made limit known as the trilogy cap applies. You can't work out your claim's value from these rules. When you discuss your losses with a lawyer, they can explain which ones you may claim and what evidence you'll need to support them.
