Claire Mathieu

Claire Mathieu is a Canadian investigative journalist based in Montréal, with more than a decade of experience covering public policy, labour issues, and accountability in the public sector. She began her career at a regional newsroom in Quebec, where she developed a reputation for meticulous document work and fair, persistent reporting. Over the years, Claire has written long-form pieces on workplace safety, procurement transparency, and the social impacts of housing and healthcare funding—work that consistently connects policy decisions to everyday outcomes. She has interviewed senior officials, front-line workers, and researchers, and her reporting often relies on FOI requests, court records, and data analysis. Claire currently leads investigations at her newsroom, mentoring younger reporters in verification practices and ethical sourcing. Colleagues describe her as calm under pressure, especially during fast-moving breaking-news cycles, when accuracy and context are essential.
