Jillian Williamson, Criminal Defence Lawyer

Jillian Williamson is a dedicated criminal defence lawyer who brings both passion and precision to every case she takes on. Based in Calgary, she focuses primarily on defending individuals charged with sexual assault, violent offences, and drug-related crimes. She has appeared at all levels of court in Alberta and is known for being a thoughtful, strategic, and tireless advocate.

Jillian’s path into defence work began at the Public Defender’s Office in Seattle, where she worked on everything from minor charges to death penalty cases. That early experience shaped how she approaches her clients—with empathy, honesty, and a commitment to listening. She’s also worked as a Crown Prosecutor, giving her a deep understanding of how the other side builds its case—and how best to challenge it.

She takes the time to understand what matters most to her clients and works hard to protect not just their legal rights, but their dignity. Her background includes clerking for the Provincial Court of Alberta and publishing in the Canadian Criminal Law Review. Through it all, her motivation remains the same: to stand up for people in their most difficult moments and fight for the best possible outcome.
