His public wake for the people of Mazatlán was held in the Mazatlán Cathedral, and hours later at the Mazatlán Opera House "Teatro Ángela Peralta" which he rescued and restored, his statue was placed at the opera's foyer. The local city theater "Teatro Antonio Haas" also bears his name. Upon his passing, the Mazatlán city government bought the Haas Canalizo family home.
