About De Rose Lawyers

Clients rate this firm highly on Google.

De Rose Lawyers is a family run personal injury and family law firm based in Toronto. According to the firm's own history, Dominic De Rose, a licensed paralegal, founded the firm after being treated like a number by an insurance company following an accident, and turned that experience into a career representing injured people instead. Two of Dominic's daughters, Mary De Rose and Diana De Rose, grew up around the practice, watching their father at work, and are now partners and lawyers at the firm alongside Dominic.

The firm describes 40 years of combined experience across its personal injury team, working on car, motorcycle, pedestrian and bicycle accident claims, slip and falls, product liability, dog bites, and cases involving traumatic brain or spinal cord injury, along with statutory accident benefits and long term disability claims. Personal injury files are handled on a contingency basis, with no legal fees unless a case is won or settled. Several lawyers at the firm, including Mary De Rose, also take on family law matters such as separation agreements, custody disputes and division of property, plus wills and powers of attorney. The firm lists dozens of Ontario communities it serves, from Ajax to Windsor, with dedicated trauma centre coverage in cities including Hamilton, Kingston, London, Ottawa, Oshawa, Sudbury and Toronto.
