A priest was stabbed live on television during morning service yesterday at Canada’s biggest church, police said.
Footage broadcast on a Catholic television station and picked up by the top-rated CTV network showed a man in jeans, a parka and a white baseball cap approach Claude Grou at St Joseph’s Oratory in Montreal.
He is seen chasing the priest and standing menacingly over Grou as he falls to the ground, scattering candles and a banner, before stabbing his victim.
Witness Adele Plamondon, told public broadcaster Radio-Canada the priest was about to start the service when “this man drew a knife and ran up to stab him.”
“I’d thought he was just going to kneel and pray like many people do,” she said.
The suspect remained silent during the assault but appeared “very determined,” Plamondon added.
Grou recovered enough to get to his feet and is seen backing away as security officers surround the assailant, who drops his knife.
Three guards restrained him while others tended to Grou, who appeared to be in shock.
The priest was taken to hospital, where his condition was said to be stable, with police reporting that he had been “slightly wounded in the upper body.” 
The church has been cordoned off.
Police did not reveal a motive for the attack.
Church spokeswoman Celine Barbeau said Grou was conscious when he was rushed from the scene.
“We are hopeful he will pull through.” she added.
Mayor Valerie Plante called the assault a “horrible and inexcusable act that has no place in Montreal.”
Saint Joseph’s Oratory, built from 1920 to 1955, sits atop the north face of Mount Royal overlooking Canada’s second-largest metropolis, and attracts some 2mn people each year.
The national shrine was founded by Brother Andre Bessette, a central religious figure among French-Canadians, who was canonized by Pope Benedict in 2010 for his devotion to the sick and disabled.
Jean-Francois Lefebvre, who was working in front of the oratory when the attack unfolded, said he saw police arrive and take away the suspect in handcuffs.
“I find this incident very unfortunate, in a place so peaceful that attracts millions of visitors,” he said.
“With what happened in Christchurch, it seems that all places of worship are being targeted,” he added, referencing a gunman’s attack at two mosques in New Zealand last Friday that left 50 dead and 50 wounded.
In 2017, a shooter gunned down six worshippers at a mosque in Quebec City.
