I practice in all areas of criminal law, but a large portion of my files focus on Constitutional arguments in drinking and driving cases. I received a Bachelor of Arts degree in 2010 from Dalhousie University in Halifax, Nova Scotia. I received my Juris Doctor law degree from Western University.

My Client Reviews Recent Summarized Cases

Called to the Bar in Ontario in 2015

I have practiced law at Aitken Robertson since 2015. In normal years I litigate different kinds of matters, including trials in the Ontario Court of Justice and summary conviction appeals before the Superior Court of Justice.

Currently, I practice in all areas of criminal law, but I focus on DUI allegations. My approach to many DUI cases is to at first take a dispassionate look at your disclosure. Disclosure is the name given for all the documents the prosecution must disclose to the defense as part of a criminal proceeding. It is always helpful if I can review disclosure and expose errors in police investigations, such as errors in warrants or other forms of intrusive investigations. Ultimately, I will review your case and situation with a view to provide practical advice customized to your needs and wants.

Trial litigation for DUI charges often involves constitutional litigation. Constitutional litigation in a DUI setting means holding police accountable to the Charter of Rights and Freedoms. I file dozens of applications each year on behalf my clients to have evidence excluded because of Charter-offending police activities during investigations. Each year I successfully get key evidence excluded from the prosecution’s case against my clients. As your lawyer, you will not be shut out from your case, and I will provide analysis to whatever degree you are interested. I want you to be comfortable, or as comfortable as one can be in the circumstances.

Some of the time an acquittal is not within the realm of possibilities, but I will still pursue the best result for you regardless of the path forward. I may also negotiate reductions to charges, so that my client can plead guilty to a Highway Traffic Act offence or other provincial offences instead of a criminal disposition. In all this, I will always be straight-forward with you about my assessment of your case.

I have had considerable success in DUI cases, including in cases where my clients are alleged to refuse or fail to provide a breath sample. I also enjoy applying my constitutional litigation knowledge to all kinds of situations, including search and seizures of guns and drugs. Other areas of my practice include assault, sex assault, fraud, theft, mischief, breaches, voyeurism, harassment, and Section 11(b) applications for undue delay.
