The Vancouver Canucks confirmed their dominance in the Northwest Division well before meeting the Colorado Avalanche on Saturday night.Vancouver captured the Northwest for the fourth straight season and fifth time in six campaigns when the second-place Calgary Flames failed to claim two points in a 4-1 loss to Dallas on Saturday afternoon. The Canucks became the second team in the Western Conference to secure a place in 2012 Stanley Cup Playoffs, and they are assured a top-three seed when the tournament begins next month.
