Multiple members of the hockey operations department were also in the house, including Canadiens assistant general manager John Sedgwick and Adam Douglas, the team's director of sports science, among others.
The Canadians' scoring machine got to work in the first period with a goal from defender Ella Shelton.
In the second stanza, crowd favorite Poulin doubled her sides' lead, scoring her 98th tally with the senior national team. The third goal, coming off the stick of forward Blayre Turnbull, led the Americans to pull Nicole Hensley from net and replace her with Maddie Rooney, but that didn't make much of a difference as Turnbull went on to score another. Teammate Victoria Bach notched the red and white's fifth and final goal.
The Americans brought the heat in the third, but couldn't solve goaltender Ann-Renée Desbiens, who maintained the shutout with 25 saves.
