Laval Mayor Stéphane Boyer announced Monday he has been diagnosed with a meningioma, a type of brain tumour. Most meningiomas are benign, though Boyer must wait for appointments with a neurosurgeon to determine what comes next.
Boyer, who became Laval's youngest mayor when elected at 33 in 2021 and was re-elected in 2025 with 59 per cent of the vote, said he experienced headaches and visual disturbances over several months before undergoing an MRI. In a social media post, he said "I feel fine, my energy levels are excellent, and I retain all my abilities."
He plans to scale back public activities this fall but will continue to fulfill his mayoral duties and attend all working meetings. "While I don't yet have answers to all my questions, I know one thing: I want to continue to be involved in my city," Boyer said in the post.
Boyer has lived with ankylosing spondylitis—an inflammatory condition that causes spinal stiffness and pain—for several years. The city has not announced a succession plan or details on delegated duties during his medical treatment.
