About Harte Law

Harte Law is a Richmond Hill law firm that focuses exclusively on medical malpractice and medical negligence claims, representing clients across the Greater Toronto Area, Ontario and Canada rather than taking on general personal injury work. Its office at 30-16 Sims Crescent is the firm's only location, and its lawyers often act as co-counsel to other personal injury firms on medical files. The team includes trial lawyers supported by an in-house nurse and physician who help evaluate the medical side of a claim.

Founder Paul Harte was called to the Ontario bar in 1994 and is a Law Society of Ontario Certified Specialist in both Health Law and Civil Litigation, with a career that has included the Wilson Hepatitis B Class Action and lead counsel work in D.P. v. Wagg. Two of the firm's other senior lawyers have each practiced there for more than twenty and twenty five years, and its newest lawyer, Joshua Harte, was called to the Ontario Bar in 2024. Harte Law works on a contingency basis, typically between 25 and 40 percent of what it recovers, and points to more than $1 billion recovered for clients over its history, including eight-figure judgments such as the $12,350,000 judgment in Brown v. Meaney and the $12,200,000 judgment in Gumbley v. Vasiliou.

The neighbourhood

Harte Law keeps a single office in Richmond Hill rather than a downtown Toronto tower. The firm says it represents clients and serves as co-counsel to other personal injury firms across the Greater Toronto Area and throughout Ontario and Canada, so most of the work its lawyers do reaches well beyond Richmond Hill itself.

Frequently asked questions

What kind of cases does Harte Law handle?
Harte Law focuses exclusively on medical malpractice and medical negligence claims. The firm's practice covers birth injury and obstetric cases, surgical errors, misdiagnosis, hospital negligence and wrongful death, and it represents clients across the Greater Toronto Area, Ontario and Canada rather than taking on other types of personal injury work.
My baby was injured during delivery. Can the firm help with a birth injury claim?
Harte Law handles birth injury and obstetric claims, including cases involving cerebral palsy, shoulder dystocia and fetal distress. The firm's published case results include settlements reached in cases where delayed delivery or fetal distress led to a child's brain injury, so this kind of claim is a regular part of its practice.
Does Harte Law take on class actions and mass tort cases, or only individual claims?
Harte Law takes on mass tort and class action work alongside individual claims. Lawyers at the firm have acted in the Wilson Hepatitis B Class Action and in mass tort claims against two physicians whose conduct affected hundreds of patients, and the firm reached a $29,500,000 class action settlement connected to a hepatitis B outbreak tied to EEG testing.
Will I have to pay anything upfront if I hire the firm?
Harte Law works on a contingency fee basis, so clients do not pay anything upfront. The fee is typically between 25 and 40 percent of the amount recovered, depending on the complexity and stage of the case, and it only applies if the firm secures compensation. Harte Law also offers a free, no-obligation consultation.
How long do I have to start a medical malpractice lawsuit in Ontario?
Harte Law's own FAQ page notes that in most parts of Canada, a claim against a healthcare professional or hospital generally has to start within two years of the date you knew, or reasonably should have known, about the mistake that injured you. Limitation periods carry exceptions and can be hard to work out on your own, so getting advice early matters. This is general information, not legal advice.
Where is Harte Law located and who does it represent?
Harte Law's office is in Richmond Hill, Ontario, and the firm represents clients across the Greater Toronto Area, Ontario and Canada, often serving as co-counsel to other personal injury firms on medical malpractice files. Its team includes trial lawyers supported by an in-house nurse and physician who help evaluate the medical side of a claim.
