After a solid performance during the lockout-shortened 1994–95 season with 25 points in 48 games, Momesso was dealt to the Toronto Maple Leafs for Mike Ridley. However, his career would go on a downward spiral after leaving Vancouver. He never found his legs in Toronto and was dealt after only 54 games to the New York Rangers, finishing the season with just 11 goals and 23 points in 73 games. In 1996–97, his production dried up completely; dealt mid-season back to the St. Louis Blues, he finished the year with just 1 goal and 4 points in 40 games.
