Professional Experience


McCarthy Tétrault LLP, Toronto

6th Litigation Associate (Called to the Bar in Ontario in 2013)


I am honoured to have spent my career at McCarthy Tétrault, where I summered and articled and spent my last six years of practice.


I represent clients involved in complex litigation, including commercial disputes, medical negligence lawsuits, and administrative law matters. I have appeared before all levels of Court in Ontario, the Federal Court, and the Federal Court of Appeal. I have acted as lead counsel on major commercial mandates. I have considerable trial experience, having been counsel in seven Superior Court Trials and one Federal Court Trial


I have developed a particular expertise in the post-secondary education sector, where I act both as a prosecutor on administrative tribunals and provide advice to adjudicators.

Diversity and Inclusion 


Ensuring that our profession is reflective of our community is my passion and mandate.


I have committed to Diversity and Inclusion in a number of ways. I have written about this important issue. Three of my recent articles can be found here:


Within my firm, I am part of a special three-person taskforce on Diversity and Inclusion, where we launched a pilot collecting and reporting on the demographics of lawyers billing on client files and launched a diversity & inclusion award at McCarthy Tétrault LLP.


Within the broader legal profession, I along with Shara Roy have spearheaded a Commercial List User Committee subgroup with a mandate focusing on Diversity and Inclusion within the Commercial List.

Mentorship & Teaching


I have benefited extensively from wonderful mentorship and I strive to bring it forward.


At McCarthy, I have taught sessions/workshops to students and junior lawyers on e-mail management, practice management, and motions advocacy.  I have been nominated for mentor of the year 16 times in the last six years.


At the University of Toronto, I have lectured on motions advocacy for the last four years. I have also lectured to students on a variety of other topics, including the life of lawyers.  I am also the Faculty Advisor to the Grand Moot team.


Pro Bono Legal Work


I have a long commitment to Pro Bono Legal work. I have been lead counsel for a criminal appeal at the Ontario Court of Appeal. I have been counsel on 6 different summary conviction offence mandates, where I successfully resolved charges on favourable terms for clients, or successfully defended clients at trial. I have acted as counsel to individuals seeking refugee asylum.

Community Engagement


I was honoured to be selected as 2018 Civic Action DiverseCity Fellow. The DiverseCity Fellow program is a highly sought-after leadership and skills development opportunity, which helps a select number of diversity and inclusion advocates in the Toronto Region to make meaningful change in their community. Last year, I collaborated with four fellows to develop an online, education platform on issues relating to affordable housing in the GTA.


I previously acted as a director with the Central Neighbourhood House (now The Neighbourhood Group), which is a 100 year old United Way agency with over 300 employees and an annual operating budget of $25M. I was a member of the Mergers Committee when Central Neighbourhood House acquired Neighbourhood Link, and doubled its size.
