Our Lawyers

Tony Kavanagh

Tony has been a lawyer in Winnipeg for 22 years and practices mainly in the area of criminal defence law. He has many years of experience in the criminal courts on both sides of the courtroom (he was a senior prosecutor for many years) so he can help you figure out the best steps from a wealth of experience and over 2 decades in the courts.

He will help you develop a multi-level strategy and tactical plan in handling your matter for trial. Tony earns the trust of his clients and will help you reduce your stress. But even if you think you should plead guilty, you’ll still need help dealing with the prosecutor and the Judge to achieve best results. Some people plead guilty without understanding the consequences and they can be very severe.

Tony believes everybody should have good experienced counsel. He offers a free consultation and accepts certain Legal Aid cases. Even if he cannot represent you directly, he will supervise your case and work with one of his associates to steer your matter in the right direction.

He also handles administrative and civil matters (particularly in the professional discipline area) and is an independent adjudicator. He teaches law students at both the Canadian Centre for Professional and Legal Education and at Robson Hall Law School (University of Manitoba).
