As a litigator, he has argued on behalf of clients before all levels of courts in Québec, as well as before the Federal Court and the Supreme Court of Canada. He is frequently engaged in complex matters at the intersection of public and private law, often involving significant strategic, reputational or political considerations.

His public law practice also includes a broad range of regulatory and compliance matters, including those relating to the environment, transportation, official languages, access to information and highly regulated products.
Prior to joining BLG, Julien clerked for the Honourable Suzanne Côté at the Supreme Court of Canada in 2018–2019. He previously worked as a journalist and researcher for various media outlets, including print, radio and television.
