Montembeault will patrol the home crease Saturday in preseason action against Toronto, per Simon-Olivier Lorange of La Presse.
Montembeault made 11 saves on 11 shots in a 3-0 exhibition win over New Jersey on Tuesday in 31:28 of playing time. He is expected to share Saturday's contest with Cayden Primeau. Montembeault is projected to start the upcoming campaign as Montreal's No. 1 netminder, while Primeau will be the backup.
