CHICAGO (AP) — Jason Dickinson, Tanner Pearson and Brock Boeser scored their first goals of the season as the Vancouver Canucks topped the winless Chicago Blackhawks 4-1. Thatcher Demko made 29 saves and Conor Garland added an empty-netter with 1:02 left to help the Canucks end a two-game slide. Vancouver scored two goals in the second period to take the lead for good. Alex DeBrincat scored a power-play goal for sputtering Chicago, which dropped to 0-4-1. The Blackhawks have been outscored 21-9 this season and haven’t led in any of their five games.
