About JT Defence Law

JT Defence Law is a criminal defence firm operating from a single office at 181 University Avenue in downtown Toronto, under the name Jacques | Tsimiklis Criminal Defence Lawyers. It represents clients across Ontario in bail hearings, impaired driving, drug possession and trafficking, fraud, firearms offences, homicide, and criminal harassment, along with professional and regulatory discipline proceedings.

Senior counsel George Tsimiklis was called to the Bar of Ontario in 1993 after articling in Ottawa under Michael Neville, Robert Selkirk, and Ken Hall, and built a defence practice there before continuing the work more broadly across Ontario. Over more than three decades, Tsimiklis has appeared before the Quebec Provincial Court, the Ontario Court of Appeal, and the Federal Court of Appeal, and has acted as a consultant in fraud related litigation before the High Court of England.

The firm's other criminal defence lawyer, Jacques Tynes, was called to the Nova Scotia Bar in 2020 and the Ontario Bar in 2025 after graduating from the Schulich School of Law at Dalhousie University, where Tynes placed in the top 10 in Canada at the Gale Cup National Moot. Tynes started out articling under Nova Scotia defence counsel and working for that province's Provincial Prosecution Service before moving into criminal defence work that now spans Alberta, Nova Scotia, Newfoundland and Labrador, Quebec, and Ontario.
