Having their superstar goaltender back in the crease was supposed to give the Canadiens a boost in their percentages. In the end, that's exactly what happened - just at the end opposite of where Carey Price was playing.
After ceding the opening goal in five straight games, the Canadiens exploded for three tallies in the opening frame, heading into the first intermission with a two goal lead. They earned those goals on the strength of some of the hallmarks of their style, including two goals in transition and two goals created by activating their defencemen (Nathan Beaulieu checked both of those boxes).
