William Kokesch, 65, was arrested Friday morning and charged with distribution and production of child pornography.
Kokesch was silent during a brief court appearance in Montreal on Monday. His bail hearing was rescheduled for Dec. 27.
The Pointe-Claire resident was a deacon for the St-Edmund of Canterbury parish in Beaconsfield on Montreal's West Island.
He also worked as a communications director for the Canadian Conference of Catholic Bishops and helped co-ordinate World Youth Day conferences in Toronto, Rome and Paris, according to the organization's website.
The Archdiocese of Montreal released a statement on Saturday saying Kokesch had been removed from all ministry and pastoral activity.
Montreal police said they seized more than 2,000 images from a computer, but did not release any other details about the allegations.
Kokesch has not yet entered a plea.
