Chris Sedoff, Jakob Pelletier and Emilio Pettersen scored for Calgary.
Dustin Wolf - who played the previous two outings - didn't dress Monday. Daniil Chechelev - who was drafted in the fourth round, 96th overall in 2020 - got the start between the pipes, with Brad Arvanitis backing him up.
Chechelev made 18 saves in the outing.
"Yeah, obviously it wasn't the result we were looking for but our effort was much better," said coach Mitch Love. "It was our best effort of the three games. I thought some of our veteran players really led the way in terms of the compete level and the expectation we're looking for.
"Give them credit, their goalie play real well, especially that second period. We probably deserved a better fate."
