About Diamond & Diamond Lawyers

Diamond & Diamond Lawyers is a national personal injury firm based in Toronto, with head offices there and in Edmonton and Vancouver and a network of smaller offices across Ontario, Alberta, British Columbia and Nova Scotia. The firm says it has practised personal injury law for about 40 years, growing from Ontario roots into a team of more than 65 lawyers. Most of its work is accident and injury claims: car accidents, slip and falls, brain and spinal cord injuries, long-term disability, medical malpractice and work-related injuries. It also handles wills and estates, corporate matters and class actions.

Diamond & Diamond takes personal injury cases on a contingency-fee basis, so clients don't pay unless the firm recovers compensation, and it offers free consultations. The firm says its lawyers will meet clients at home or in hospital when an injury makes travel hard, and it runs a round-the-clock intake line, 1-800-567-HURT. Its named partners include Jeremy Diamond, Isaac Zisckind and Sandra Zisckind, the managing partner. In Kitchener the firm keeps an office at 288 Frederick Street, serving clients across Waterloo Region, though the firm itself is based in Toronto.

The neighbourhood

Diamond & Diamond's Kitchener office sits at 288 Frederick Street, though the firm itself is based in Toronto. It's on the same downtown Kitchener street as the Region of Waterloo courthouse a few blocks south, near the King Street core and the ION light rail's Frederick stop.

Because the firm handles injury cases where clients are often still recovering, it emphasizes travelling to meet people at home or in hospital, so getting to Frederick Street isn't always necessary for someone in Waterloo Region.
