Commencing my practice in 1984, I later acquired the practices of Harry Robertson and John Robertson Q.C. in 1999, and founded Aitken Robertson Barristers & Solicitors. With over 35 years of experience as a criminal lawyer, I have defended a full range of criminal charges. From impaired driving causing death to domestic assault, I have taken thousands of cases to trial and have negotiated even more favourable resolutions for clients without proceeding to trial at all. I have built a successful firm that reaches far across southern, central and eastern Ontario, mentoring high caliber lawyers and paralegals. I continually invest in ongoing legal education for both myself and my staff to ensure that the Aitken Robertson firm is abreast the latest research and criminal law evolutions.

My long career has shown me that despite many files being similar as to the facts, the aspirations and needs of each client are incredibly unique. My approach is to first listen to my client without judgement in order to get their side of the story. The vast majority of my clients are ordinary good people that have made a bad decision or have been unlucky as to how an evening unfolded. Second, at trial, I not only focus on what the Crown witness says, but try to analyze why they chose that particular wording or phrase in their answer when there were many possibilities. I have found this approach to be highly effective in cross examination and can assist in probing whether a particular witness is lying or is biased against my client.

The conversation I have with a potential client is pretty simple; I promise I will do my best. I will devote my time to improve your chances, and to win where I can. I undertake to give honest, blunt advice as to what the realistic range of outcomes are. In my years of trials and in the legal trenches, I have seen just about everything. Clients benefit from the wisdom and experience I can offer. My clients trust me. If you hire me, I think you will too.

At Aitken Robertson, we place great value on continuing legal education. By attending annual training seminars and courses, we improve our legal knowledge and stay abreast the latest criminal law developments.

  • D.U.I. Tactics, Intoxilyzer 5000C & 8000C Training, Atlanta Georgia 2014. This course was held specifically for the Aitken Robertson firm with one of America’s best D.U.I. attorneys, Mr. Bubba Head, and top drug recognition expert Ron Lloyd, instructing.
  • Metrology Program, hosted by National College of DUI Defense’s (NCDD), Atlanta, Georgia 2015.  Metrology is the science of measurement and is critical for understanding the proper operation and deficiencies of breath testing instruments.
  • Intoxilyzer 8000 Operation, New Orleans, Louisiana 2016. The Intoxilyzer 8000 is used most frequently by Ontario police. This course was held by some of the most prestigious and renowned attorneys, experts, and programming engineers in North America.
  • Serious Science for Serious Lawyers: Advanced Course in Blood Alcohol Analysis & Trial Advocacy, hosted by National College of DUI Defense’s (NCDD), Ft. Collins, Colorado 2016.  The most advanced course in all of North America, enrolment was limited to twenty lawyers with myself being the only Canadian lawyer present.
  • Scientific Evidence in Breath Test Cases, Quebec 2016.
  • Drug Recognition Evaluation, National College of DUI Defense, Hollywood, California 2019. As one of three Canadians to attend, this course demonstrated how to best cross examine drug recognition experts. Specialists instructed on the 12 steps the police need to undertake to ensure any conclusion they draw as to drug impairment, is valid.

One summary conviction appeal, prepared by colleague Edwin Boeve, was argued by me at Superior Court, a case which dramatically changed the law regarding when an accused must be given rights to counsel.

  • I own an Intoxilyzer 8000TM, the same breath testing instrument used by Ontario police. With such a device, myself and my team are able to develop our trial skills and know if the instrument was not working or being operated properly prior to your D.U.I. charge.
  • For two decades I was retained by the Ministry of the Attorney General to be a part time Assistant Crown Attorney. Seeing the other side of a case, in fact prosecuting, provided me with insight as to the strategies of my opponent, which I now use fully in criminal defence.
