At the trade deadline in 1991, Momesso was dealt to the Vancouver Canucks in a monster six-player deal along with Geoff Courtnall, Cliff Ronning, and Robert Dirk for Garth Butcher and Dan Quinn. The deal would prove to be a heist in favour of Vancouver, as all four players they acquired would be significant contributors for several seasons. Momesso got his Canuck career off to a fine start, recording 6 goals in 11 games to help the team on a successful late-season push to qualify for the playoffs.
