Melissa Blais, 34, a mother of two from Yamachiche, Quebec, disappeared in the early hours of November 2, 2017, after an evening out with friends in Louiseville. Her last confirmed sighting was about 2:15 a.m. as she left a bar in the center of town. She was driving a black 2011 Toyota Corolla that also vanished after that night.

The Sûreté du Québec mounted a large search: ground crews, aircraft and divers searched areas including the Petite Rivière du Loup and parts of the St. Lawrence River, but no sign of Melissa or her vehicle was found. Police established command posts in Louiseville, offered a reward and described the disappearance — particularly the absence of any physical evidence and the missing car — as unusual and baffling.

Family members have kept the case in the public eye with events and outreach; posters with Melissa’s information were even placed on transport trucks traveling across North America. The investigation remains open and unresolved.

If anyone saw Melissa, her black 2011 Toyota Corolla, or has information from that night, please come forward.
