Head coach Sheldon Keefe confirmed his starting goaltender Sunday after practice.
Frederik Andersen has started every playoff game for the Maple Leafs over the past four seasons but injuries and performance saw Campbell pass Andersen on the Maple Leafs depth chart in the second half of the season.
Campbell made 22 starts for the Maple Leafs this season, one less than Andersen, but 19 of them came in the team's final 25 games after Andersen went down with an undisclosed injury on March 19. Campbell posted a 17-3-2 record with a .921 save percentage and two shutouts this season while Andersen had a 13-8-3 record and career-worst .895 save percentage.
