As a former Crown prosecutor, Mr. Stiles brings a wealth of knowledge and experience to the Aitken Robertson team.

After completing a two-year contract with Alberta Justice and Solicitor General, Mr. Stiles returned to Ontario to finish his masters degree in constitutional law. As a Crown, Mr. Stiles became accustomed to rigorous criminal litigation, often acting as lead counsel in cases involving expert witnesses and complex evidentiary issues. He has prosecuted a wide range of offences in various levels of court–from traffic matters to a Queens Bench jury trial. His courtroom experience includes cases involving:

  • Arson
  • Mischief
  • Break and enter
  • Robbery
  • Theft (over and under $5000)
  • Auto theft
  • Fraud
  • False pretense
  • Uttering threats
  • Extortion
  • Assault (aggravated, assault causing bodily harm and assault with a weapon)


  • Sexual offences
  • Criminal harassment
  • Possession of prohibited weapons (tasers, switchblades etc.)
  • Firearms offences
  • Dangerous driving causing death
  • Obstruction of justice

As a Crown, Mr. Stiles also dealt with many impaired driving, over .08 and refusal cases. This experience left him with a very thorough understanding of the Crown’s proof requirements as well as the range of viable defences available to the accused when faced with driving-related charges. Also, having completed an LL.M. in constitutional law, Mr. Stiles has a firm grasp of his client’s Charter rights in all stages of the criminal process. This is particularly important in the context of impaired driving, where even the slightest breach of the accused’s rights can lead to an acquittal at trial.

Mr. Stiles’ combination of education and hands-on experience is a crucial asset when defending against criminal allegations. From minimizing risk to vigorous litigation at trial, Mr. Stiles strives to ensure best outcomes for all his clients. Since beginning with the firm, his hard work and dedication has routinely paid off in the form of non-criminal resolutions, discontinued prosecution and not guilty verdicts at trial.

Mr. Stiles primarily works out of the Oshawa Office, but he still does considerable amount of work in the Peterborough, Lindsay areas.

Mr. Stiles is a very proud Trent University alumnus and is thrilled to call Peterborough home again. As an avid outdoorsman and someone who much prefers smaller community living, Peterborough offers the lifestyle and collegial work environment he values.

Philip Stiles is a lawyer and is licensed by the Law Society of Ontario.

I had my first trouble with law couple of months and we found Edmund Chang. He helped me through all the process professionally moreover, he really cares about my best interest, he will check if I comfortable with all decisions we were going to make and if not, he will not push it. Other things that really stand out, he is approachable as well as responsive to follow up. In the end, we settled the case and I can move more

I was charged with over 0.80 and Impaired Driving charges. I didn't think I had any chance, but Justin Marchant managed to get me out with a careless driving charge. Thanks to him, I don't have a criminal record!!! Very friendly, sharp, professional, and dedicated individual. He did a great job prepping me for the trial, and prepping for the case. I highly recommend this firm, as if it wasn't for them, I'm not sure what would have happened to my life. I made a nasty mistake, one which I will never ever make again. Some lessons have a big price to be more

Mr. Marchand is an amazing lawyer. He is very personable and professional. My case was a very long and drawn out case, but Mr. Marchand always kept up with everything and I was always well informed. I really appreciated that he would take the time to fully explain his thought process/strategy and was never condescending. Even though this was a stressful time, Mr. Marchand made it a great experience and took care of more

Once again amazing ! I am writing this review as I always refer my friends to this firm. THEY ARE THE BEST ! My friend was pulled over at the us border on a random check and in turn got charged with a refusal. My friend did not know that refusing to take a breathalyzer was a criminal offence. In fact as soon as he realized it he asked the officers to take it but they refused him. In turn he was charged with a refusal. Aitken Robertson specializes in DUI and cases such as this.. so it was an immediate call to them that i put in for him. Right then and there they took over. As usual, they offered a payment plan and of course they took care of everything all the pre-trial meetings etc. Justin was the laywer for him and not only is he the MOST thorough he is the most out for justice. He found the errors that the officers made and he used it to my friends advantage. He went above and beyond to find the best resolution with the crown. He went above and beyond to give my friend all his options. And the best part is that NO CRIMINAL CHARGES. It was reduced basically down to a speeding ticket as a result of Justins hard work. The whole firm is stellar. They take time to go through your disclosure to confirm any and all details are correct.The justice system is a corrupted one and im thankful these lawyers know how to find a way to help us through that. Justin once again did an amazing job. Susan at the firm is great she helps out with payment plans etc. Brenda is great. Robert of course its just a great team of laywers. Do not go anywhere else ! I will recommend them time and time more

When my daughter's boyfriend had a problem I looked up Jordan Tekenos-Levy. Jordan did an amazing job defending this young man. He showed compassion and care in a very sensitive issue. Jordan is a great lawyer, he fights hard for his clients and ensures their loved ones are kept in the loop during the entire process. He is honest and doesn't sugar coat the situation. I would highly recommend his services. We owe him a huge debt of gratitude and I wish him all the best in the more

I was falsely accused of a crime and I sought out representation. I did not know exactly where to go, I was in a panic as I've never seriously run afoul with law enforcement. Mr. Nathan Baker and his staff were assigned to my case, and I am thankful that they were. Knowing I was innocent I still was worried about how everything was going to play out as I wondered 'how could this even be happening'. Mr Baker and his staff helped walk me through the court process that was completely unfamiliar to me, besides what Id seen on television. It was a two year process, and every step of the way all my questions and inquisitions were answered and put at ease. I give this Firm my full endorsement, they believed in me, supported my case and followed through on every detail pertaining to it, and defended me to a correct Not Guilty verdict. For that I will be forever grateful. I've never had the need for an attorney to represent me before the false accusation, and I hope I never need it again. But if I do, I'd want this firm to represent more
