Jul 19, 2025 in News --> Medication Errors
Most of us head to the hospital expecting help — not harm. In Canada, we trust our healthcare system and the professionals who care for us. But even with skilled doctors and nurses, mistakes can and do happen. A missed diagnosis, a wrong prescription, or an error during surgery can change a life in an instant.
While Canada’s healthcare system has a strong reputation, it’s not perfect. Medical errors are more common than many people think, and when they happen, the impact can be devastating for patients and their families.
In this post, we’ll take a closer look at how medical mistakes happen, share real examples from right here in Canada, and explain the legal options available if you or someone you love has been affected by a medical error.
You might be surprised to learn just how often medical errors happen. The Canadian Institute for Health Information (CIHI) reports that 1 in every 17 hospital stays in Canada results in some kind of harm. That’s around 150,000 incidents a year. And these mistakes aren’t always minor. Some lead to permanent disability or even death.
Common types of harm include:
Another report from the Canadian Patient Safety Institute estimates that medical errors contribute to 28,000 deaths annually across the country. These numbers are staggering, heartbreaking, and they highlight why accountability and prevention matter so much.
Errors in hospitals can happen in different ways, from charting mistakes to poor communication between staff. Here are some of the most common:
This includes giving the wrong drug, delivering the wrong dose, or failing to consider allergies or interactions. These errors are often the result of rushed care or unclear records.
When a condition like cancer, stroke, or infection is missed or diagnosed too late, treatment might come too late—and that delay can be deadly.
Operating on the wrong body part or leaving instruments inside a patient are rare but very serious mistakes that fall under hospital negligence.
Infections like MRSA, or wounds that become infected after surgery, are often the result of poor hygiene or missed protocol.
Errors during childbirth can lead to long-term complications for both mother and baby—injuries that often could have been avoided with proper care.
Here are just two real-life examples that shine a light on the human cost of medical errors in Canada:
Background: In 2011, Mary Fleury had an appendectomy. The pathology exam, conducted by Dr. Olayiwola Kassim at West?Parry?Sound Health Centre, failed to detect cancer. Four years later, in 2015, a laparoscopy revealed metastatic adenocarcinoma of her appendix. She died in 2016 at age 45.
Court ruling:
Damages awarded:
Background:
In December 2008, 24-year-old Danielle Boyd arrived at Hanover ER with headache, left-side numbness, slurred speech—all stroke signs. Dr. Edington diagnosed migraine, hypertensive crisis, or alcohol use. He lowered her blood pressure by ~37% over 3 hours. Later that night, she was transferred, given heparin, but too late. Diagnostic imaging revealed vertebral artery dissection. She suffered a severe stroke, resulting in paralysis from the neck down.
Justice Sproat (Ontario Superior Court, 2014 ONSC?1130) found Dr. Edington breached the standard of care by:
Danielle Boyd received $15 million, one of the highest malpractice awards in Canada.
These stories aren’t just legal cases—they’re reminders of the importance of speaking up and seeking justice when something goes wrong.

Mistakes don’t just happen in hospitals. They also happen in long-term care homes, clinics, and other medical facilities.
In this post on long-term care negligence, we looked at issues like residents being left unattended or given the wrong meds—problems that come down to poor staffing and training.
Meanwhile, emergency room malpractice during holidays is a growing issue. Hospitals often get overcrowded, and critical diagnoses can be missed when staff are overworked or under pressure.
A recent legal victory featured in this article—Neinstein Personal Injury Lawyers Help Raise the Bar—highlights how successful claims can actually drive change. By raising compensation benchmarks in court, these cases also send a message to the healthcare system: Do better.
