After hearing his performance, filmmaker Léa Pool offered Dupuis one of the principal roles in her film Maman est chez le coiffeur.
In 2007, Dupuis was invited to take part in the telethon, "Téléthon Opération Enfant-Soleil," where he met singer Annie Villeneuve.
Dupuis also appeared in performances at the theatre Hector-Charland, one of which was a fund-raiser for the "Fondation des Auberges du Cœur," an organization involved in providing shelter to homeless young people.
He debuted two of his own compositions, along with interpretations of a range of pop standards, accompanied by two other musicians and featuring three guest performers.
