About Thomas Gold Pettingill LLP

Thomas Gold Pettingill LLP (TGP) is a Toronto litigation firm concentrated on insurance and commercial disputes, working from an office at 150 York Street in the city's financial district. The firm's own lawyer directory lists 25 lawyers, and TGP describes its client base as based in downtown Toronto but international in reach. It acts as counsel for major Canadian and international insurers, as well as for municipalities, corporations, universities, colleges, professionals, and private individuals, in complex and precedent-setting cases before all levels of court and tribunals.

TGP's practice covers insurance litigation, accident benefits and SABS claims, coverage opinions and advice, and Licence Appeal Tribunal work, along with commercial, municipal, and education sector litigation. The firm keeps searchable databases of LAT decisions and commercial and tort case law on its site, updated monthly. One of its partners, Alexander D. Pettingill, took part in the settlement negotiations, alongside former Supreme Court of Canada Justice Frank Iacobucci, for a $4 billion class action settlement covering approximately 90,000 Indian Residential School claims.

Can TGP defend a university or college that's been named in a lawsuit?
Yes. The firm has an Education Claims practice covering campus security, educational malpractice, professional liability, and sexual assault or harassment defence, and one of its partners has acted for what the firm describes as virtually every major university in Ontario.

Yes. Municipal Litigation is a listed practice area, covering Minimum Maintenance Standards claims, occupiers' liability, motor vehicle claims, and coverage or contractual disputes involving municipalities.
