About Diamond & Diamond Personal Injury Lawyers

Diamond and Diamond Personal Injury Lawyers is a national personal injury firm headquartered in Toronto, with offices across Ontario, Alberta, British Columbia, and Nova Scotia. The firm was founded by Jeremy Diamond and Isaac Zisckind and focuses on personal injury claims, including car and motorcycle accidents, slip and falls, brain and spinal cord injuries, dog bites, wrongful death, and long-term disability. It takes these cases on a contingency fee basis, so clients don't pay unless the firm recovers compensation for them, and it offers free consultations.

The firm opened a Sudbury office at 31 Larch Street in October 2021, with a mandate to serve clients across Northern Ontario rather than the city alone. Patrick Poupore leads the Sudbury office. Poupore was called to the Ontario bar in 2003, has appeared as counsel before the Superior Court of Justice, the Divisional Court, and the Federal Court, and belongs to the Canadian Bar Association and the Ontario Trial Lawyers Association.
