He spent ten summers as a counselor at Camp Mariste in Rawdon that had outreach to poor youth as its mission, "to be with them, to listen to them, to care for them".

At the age of 19 he entered engineering school, the École Polytechnique de Montréal, but inspired by the example of young priests at camp and their involvement in the Focolare Movement, he left school at 20 and joined a Marist mission to Haiti, devoting ten months to teaching languages, mathematics, and catechism.

After serving as parish vicar of Saint-Urbain and Sainte-Dorothée from 1995 to 2000, he studied theology at the Institut Catholique de Paris for three years.

[1] Faubert also co-hosted the television magazine show “Parole et Vie” from 2004 to 2010, which explored contemporary spiritual and religious issues.

A seminary teacher thought Faubert's expertise in ecclesiology suited Montreal's need to transform itself into a missionary church with greater lay responsibility.

[5] In August Lépine named his two auxiliaries vicars general, giving Faubert responsibility "for co-ordinating all the pastoral and missionary activities carried out within the diocese", effective 1 September.
