About Thomson Blackburn Lane Lefebvre LLP

Thomson Blackburn Lane Lefebvre LLP, which does business as TBLL Advocates, is a small litigation firm with an office in the DBRS Tower at 181 University Avenue in Toronto's financial district. The firm's LinkedIn company page lists a 2020 founding year. Four lawyers carry the firm's name: James P. Thomson, Janice E. Blackburn, James R. Lane and Julia L. Lefebvre, though Blackburn has since retired from active practice.

The practice concentrates on defending professionals and the insurers who cover them. Its lawyers act for accountants, engineers, architects, financial advisors and health practitioners in professional liability claims and in disciplinary hearings before regulators such as the Law Society of Ontario, the College of Physicians and Surgeons of Ontario and Professional Engineers of Ontario. The firm also handles insurance coverage disputes, media and defamation matters for news organizations and publishers, and marine and transportation claims for shipowners, insurers and freight forwarders.

Appellate work is a particular focus. The firm's advocates appear regularly before the Court of Appeal for Ontario and have argued cases at the Supreme Court of Canada. In one professional liability matter, the firm represented design professionals over the structural design of the Rogers Centre stadium dome roof.
