Daniel Sedin returned to the ice after suffering a concussion last month and had an assist in helping the Canucks cut their deficit in the opening-round playoff series to 3-1. Vancouver, which had the best regular-season record in the NHL, will host Game 5 Sunday.
Anze Kopitar gave Los Angeles the lead with 7 minutes to go in the first period but Schneider was perfect the rest of the way while making 43 saves. Schneider made his second straight start in place of a struggling Roberto Luongo and is expected to start Sunday as well.
Jonathan Quick stopped 27 shots in the loss.
