Nice to meet you. My name is Lex.


I’m a Montreal-based lawyer with an ambitious practice rooted in a commitment to social, environmental, and economic justice. I work for a groundbreaking law firm known for class actions and public interest litigation in areas like constitutional law, environmental law, and corporate accountability. I’m also a current affiliate at the Citizen Lab, where I do law that feels like science fiction. I have degrees in both the common law and civil law from McGill University and am a fully licensed member of both the Law Society of Ontario and the Barreau du Québec.


As a former Supreme Court clerk to the Chief Justice of Canada, I believe that appellate and public interest litigation can be important tools for law reform. My practice as an advocate is informed by experience working on high-profile research and advocacy issues for organizations like the Citizen Lab, the Canadian Civil Liberties Association, the Canadian Internet Policy and Public Interest Clinic and the Berkman Klein Center at Harvard University, as well as my experience on governing and advisory boards for organizations like Canadian Journalists for Free Expression, the Digital Justice Lab, Head & Hands, and the Concordia University Board of Governors.


I teach part-time at McGill University’s Faculty of Law and love working with and learning from students. In Winter 2021, I designed and taught an upper-year seminar called Law and Poverty (syllabus here). In Summer 2020, I designed and taught an intensive seminar called Technology and the Charter (syllabus here).


I am regularly asked to speak on topics related to constitutional and human rights, law reform, and emerging technology. I believe in the importance of public conversation, and—from testimony before Parliamentary committees to keynote talks at hacker conferences—my intention has been to engage audiences on these difficult issues with integrity and impact. My academic work has been presented before audiences at Harvard University, the University of Pennsylvania, McGill University, University of Waterloo, Humboldt University of Berlin, and the University of Toronto, among others.


My work has featured in various academic publications and peer-reviewed journals (see e.g., Law, Metaphor, and the Encrypted Machine, Advancing Human Rights by Design in the Dual-Use Technology Industry, Towards Digital Constitutionalism). I have also authored and co-authored a number of major reports, policy briefs, and international submissions (see e.g., Bots at the Gate, Shining a Light on the Encryption Debate, Planet Netsweeper, Submission to the UN Special Rapporteur on Technology-Facilitated Violence, Abuse, and Harassment). My focus in 2021 is on long-form essay writing.
