John Carpay is a Netherlands-born Canadian lawyer, activist, and columnist who immigrated to Canada as a child and grew up in Alberta. He is the founder and president of the Justice Centre for Constitutional Freedoms (JCCF), established in 2010, where he focuses on advocacy for constitutional freedoms and civil liberties, including free speech, religious liberty, and opposition to government regulations and overreach. His work involves high-profile legal challenges, particularly during the COVID-19 pandemic contesting lockdowns, vaccine mandates, and restrictions on public gatherings. Carpay collaborates with conservative and libertarian media outlets as a columnist for publications such as the Western Standard and Rebel News, and has worked with figures like Ezra Levant. His career has been marked by controversy, including allegations of misconduct. On September 2, 2025, he was disbarred by the Law Society of Alberta following an investigation into unauthorized access to government buildings and other ethical breaches related to his advocacy work. Despite this, he remains a vocal figure in Canadian conservative circles, emphasizing anti-regulation stances and support for parental rights in education. Critics have accused him of promoting fringe views and associating with controversial right-wing elements.
