About Buie Cohen LLP

Buie Cohen LLP is a small law firm in Toronto with more than 50 years of combined legal experience between its two founding lawyers, Catharine M. Buie and Harold B. Cohen, Q.C. Buie has since retired from active practice, and Cohen continues as the firm's senior partner, working directly with clients rather than routing questions through junior staff or assistants. The firm describes its approach as that of a small town lawyer practicing in a large city, built around long term client relationships rather than one off transactions.

Cohen's practice centers on estate planning, personal injury, and corporate and commercial matters, including construction liens, and draws on more than 20 years as a Deputy Judge before moving into private mediation work. Buie's background is in civil litigation, with cases argued at every level of the Ontario court system up to the Supreme Court of Canada, along with formal training in mediation and alternate dispute resolution. That combination shapes the firm's broader practice, which spans wills and estates, collaborative family law, real estate, and mediation, and treats ADR as a first option rather than a last resort before litigation.

The neighbourhood

Cohen's office is in the Forest Hill North area of midtown Toronto, a quiet, established residential part of the city near Eglinton Avenue West and Bathurst Street, with parks such as Ben Nobleman Park nearby. It's a fitting setting for a practice built around mediation, estate administration, and family matters rather than courtroom volume, work that tends to call for a calmer, more private meeting space than a downtown office tower. Buie's earlier office was on Stafford Street on the west side of downtown, closer to King Street West, and it remains listed as a contact address even though Buie has retired from practice.
