During your medical treatment, if a doctor, surgeon, nurse, or hospital in Mississauga happens to harm you through a mistake they shouldn’t have made, you may have grounds for a medical malpractice claim. At Reyes Tam Law, our Mississauga medical malpractice lawyers help patients and families hold negligent healthcare providers accountable.
These are some of the most complex claims in Ontario law, and you shouldn’t have to untangle them on your own. We review your case for free, and you pay nothing unless we win.
How Do I Know if I was the Victim of Medical Negligence?
Not every bad outcome in medicine is malpractice. Doctors can’t guarantee results, and some risks are simply part of treatment. What matters is whether your provider’s care fell below what a reasonably competent professional would have done in the same situation.
Common forms of medical negligence we see in Mississauga include:
- Misdiagnosis or delayed diagnosis of a serious condition like cancer, stroke, or sepsis
- Surgical errors, including wrong-site surgery or instruments left inside a patient
- Medication errors, such as the wrong drug, wrong dose, or a dangerous combination
- Birth injuries, including failure to monitor fetal distress or delayed C-sections
- Anesthesia errors that cause lasting harm
- Hospital or nursing negligence, like failure to monitor a patient, preventable falls, or hospital-acquired infections
So how do you tell the difference between an unfortunate outcome and outright negligence? Usually, it comes down to one question: would another qualified doctor, given the same information, have acted differently? If the answer is yes, you may have a claim worth pursuing.
How Do You Prove Medical Malpractice in Ontario?
Ontario law requires you to establish three things to succeed in a medical malpractice claim:
- Duty of care – your healthcare provider owed you a standard of care (this is rarely disputed once a doctor-patient relationship exists)
- Breach of that standard – their care fell below what a reasonably skilled provider would have delivered
- Causation – that breach directly caused your injury or made it worse
Proving breach and causation almost always requires an independent medical expert to review your records and provide an opinion on what should have happened. This is different from filing a complaint with the College of Physicians and Surgeons of Ontario (CPSO), which can discipline a provider but doesn’t get you compensation.
A civil claim is the path to financial recovery, and it’s where our Mississauga medical malpractice lawyers focus.
How Long Do You Have to File a Medical Malpractice Claim in Ontario?
Under Ontario’s Limitations Act, 2002, you generally have two years from the date you knew, or reasonably should have known, that your injury was caused by negligence. This is known as the discoverability rule, and it’s why the clock doesn’t always start on the date of the actual procedure or diagnosis.
There are exceptions. If the injured person was a minor at the time, the two-year period typically doesn’t begin until they turn 18. But waiting is still risky: medical records get harder to obtain, memories fade, and expert reviews take time to arrange. The sooner you speak with a medical malpractice lawyer in Mississauga, the more options you’ll have.

Frequently Asked Questions
Can you sue a doctor for a missed diagnosis that got caught later by another doctor?
Yes, if the delay caused real harm, such as a condition progressing to a more serious stage. The claim isn’t about the mistake alone but about the measurable harm that resulted from the delay in proper treatment.
Does it matter if the malpractice happened at a private clinic vs. a public hospital in Mississauga?
The legal standard is the same either way, but the process for gathering records and identifying the responsible parties can differ. Public hospitals often involve multiple staff and departments, which we account for during our investigation.
What if the doctor who harmed you has since left Ontario or retired?
You can still pursue a claim. Malpractice liability generally follows the provider and their insurer, not their current employment status or location, though it can add extra steps to locating records and serving legal documents.
Can you file a malpractice claim on behalf of a deceased family member?
Yes. Ontario law allows family members or an estate representative to bring a claim if negligent medical care contributed to a loved one’s death, including claims for the family’s own loss and grief under the Family Law Act.
