“This was an isolated attack, and there is nothing to link it to terrorism,” said police spokeswoman Caroline Chevrefils while speaking to AFP. Cheverfils claims Friday’s assailant was “known to police.”

The stabbing took place at Canada’s St. Joseph’s Oratory, located in Montreal. The church is one of the country’s largest, and attracts about two million visitors each year, according to AFP.

“I find this incident very unfortunate, in a place so peaceful that attracts millions of visitors,” said Jean-Francois Lefebvre, who works at St. Joseph’s and was a witness to Friday’s attack. Canadian politicians also spoke in support of the priest and decried the violence, including Canadian Prime Minister Justin Trudeau, who sent his wishes to Grou via Twitter.

What a horrible attack at Saint Joseph’s Oratory in Montreal this morning. Father Claude Grou, Canadians are thinking of you and wishing you a swift recovery.

This is not the first time a religious facility has been attacked in Canada. In January of 2017, twenty-something university student Alexandre Bissonnette shot and killed six people who were attending mosque in Quebec City, Quebec. Bissonnette is currently serving a life sentence for the crime.
