The Canucks are coming off an embarrassing 7-3 home loss to Anaheim in their season-opener Saturday, with starter Cory Schneider getting pulled in favour of Luongo after allowing five goals on 14 shots.
Luongo allowed two goals on 12 shots — both by Teemu Selanne — that gave the Ducks 6-2 and 7-3 leads.
"I had it figured out a couple of days ago, and nothing that happened (Saturday) night changed my mind," Vigneault told reporters after the team's morning skate.
Luongo, the Canucks' former No. 1, is on the trading block after being displaced by Schneider in last spring's playoffs.
