An independent audit of more than 80 years of files involving nine Quebec Catholic dioceses found at least 87 abusers among church personnel, according to a summary of findings released Wednesday.

Retired Superior Court justice Andre Denis reviewed the files of 6,809 people employed between 1940 and 2021 and uncovered 87 employees who were the subjects of confirmed or well-founded sex abuse allegations involving minors or vulnerable adults.

Denis says his mandate was twofold: first, to root out people accused of abuse who were still working for the church, and second, to offer the church a historical portrait of how many employees faced credible allegations. He says fewer than five of the 87 people were still working for the church by the time he finished his review.

"They're counted on the fingers on one hand, but those who had allegations, they were removed from their positions and submitted to disciplinary committees of the respective dioceses," Denis said in an interview Wednesday.

The 87 people he identified represented 1.28 per cent of the people employed by the church during the period studied.

The audit involved the dioceses of two church jurisdictions -- Montreal and Gatineau -- which include several major cities, like Joliette, Longueuil, St-Jerome and Valleyfield.

"The church needed to know what proportion -- it's certain there are those who didn't file a complaint, but it's not, say, 25 per cent of cases," Denis said, adding that while the actual number of people accused of abuse is likely a bit higher than 87, he said he feels that number is more or less accurate.

Denis also said he was unable to detect any systematic transfer of priests from one parish to another once abuse or misconduct had been discovered.

He began his work in December 2020 and said he had access to all archival documents, including those typically only viewed with the archbishop's approval. In sum, Denis said he consulted nearly 10,000 documents, including the files of bishops, priests, deacons, pastoral associates and diocesan staff.

"I believe the archives are reasonably complete and give a good explanation of about 60 per cent of the territory of Quebec," Denis said.

The 87 people he identified worked for a diocese or parish but not for institutions such as colleges or boarding schools operated by religious congregations that fall outside the purview of the bishops who oversee the two jurisdictions that were studied.

The bishops overseeing those two regions said in a statement Wednesday they welcomed Denis's report, adding that it was important to confirm that no abusers were currently working for the church.

"The goal of the review is to ensure that no member of the pastoral personnel currently serving in our parishes has been the object of substantiated allegations of sexual abuse," Archbishop Paul-Andre Durocher of the Gatineau archdiocese said in a statement.

"Our parishioners can be confident that a thorough audit process has been carried out."

The bishops said, however, that it's possible not all incidents of sexual abuse were reported and that it's also possible no records were kept for certain instances of abuse. It's likely other victims will come forward, they added.

Archbishop Christian Lepine had first announced the audit in 2019 and said at the time its aim was to uncover the truth, whatever that may be.

On Wednesday, he said in a statement the review was needed to assess the issues in each diocese and to take steps to ensure that all documents in the church's possession have been reviewed properly.
