About Thomson Rogers LLP

Clients rate this firm highly on Google.

Thomson Rogers LLP is a Toronto litigation firm that traces back to 1935, when Edson Haines opened a one lawyer practice under the name E. L. Haines and Co. The name changed several times as partners joined over the following decades: Haines & Haines in 1939, then Haines, Thomson, Rogers in 1950, and a longer version of that name through the 1950s, before it was shortened to Thomson, Rogers in 1966. The firm moved into its office tower at 390 Bay Street in 1973 and has practised from there ever since. It marked its 90th anniversary in 2025 by adopting its current name, Thomson Rogers LLP.

The firm's work centres on personal injury and medical malpractice litigation, alongside family law and planning, municipal, and expropriation law, plus class actions and environmental law. Its lawyers appear before the Superior Court of Justice and the Court of Appeal for Ontario, and before administrative boards and tribunals across the province. Six former partners have gone on to become judges in Ontario, and since 2011 Canadian Lawyer magazine has selected the firm as one of Canada's Top 10 Personal Injury Boutiques.

In the community

  • In 2025, to mark its 90th anniversary, the firm donated $30,000 to Camp Dawn, a program in Waterford for adults with acquired brain injury, enough to cover all camper costs.
  • The same anniversary gift included $30,000 donations to the Ontario Professional Planners Institute and to StepStones for Youth.
  • The firm has been a Diamond Sponsor of the Ontario Brain Injury Association's provincial and Toronto ABI conferences, including in 2023 and 2024.
  • It has also supported the Toronto ABI Network, which connects services for people living with acquired brain injury in the city; the network's own site credits Thomson Rogers with supporting its website.
