One person dead after shooting during police response near Ottawa's ByWard Market

One person is dead following a police-involved shooting in Ottawa's ByWard Market, according to Ontario's police watchdog.

The Special Investigations Unit says the Ottawa Police Service received a report of a man in the area of St. Patrick Street and Parent Avenue just after 2 p.m. on Sunday, "who was in possession of an edged weapon."

Officers located the man on St. Patrick Street, between Parent Avenue and Sussex Drive.

"There was an interaction, and two officers discharged their firearms. The man was struck," the SIU said, adding the victim was pronounced dead at the scene.

A witness told CTV News Ottawa they heard four gunshots.

"We had customers in and we heard four gunshots," Jean -Bergeron of Galerie D'art Jean-Claude-Bergeron Expositions said.

"I ran to the door and I saw a guy lying down on the street that had been shot."

Ottawa police said just after 3 p.m. on Saturday that officers had responded to a 911 call regarding a person with a knife.

"During the response one person was shot," the Ottawa Police Duty Inspector said on Twitter.

An Ottawa paramedic spokesperson tells CTV News Ottawa an adult was pronounced dead at the scene from a gunshot wound.

The SIU has invoked its mandate, and is investigating the "fatal police-involved shooting."

Three investigators and two forensic investigators have been assigned to the case.  The SIU says two subject officers and two witness officers have been designated as part of the investigation.

The SIU investigates the police actions resulting in serious injury or death.

Yellow police tape was blocking St. Patrick Street, between Parent Avenue and Sussex Drive, on Sunday evening.

"I've seen a lot of change happening in the neighbourhood. When I saw the police and the barricades, I was, obviously, curious what was happening," Garfield Fisher said after seeing the police investigation.

"There's been a trend of more things happening... it's concerning."

Ottawa police chief Eric Stubbs wouldn't comment on the shooting when speaking to reporters Monday ahead of the Ottawa Police Services Board meeting, citing the SIU investigation, but he said the officers involved were being supported.

"When they go to work, this is not how they want to end their shift," Stubbs said. "In terms of their status, we obviously monitor each officer during a traumatic event to make sure they get the support they need. They get some time off and we talk to each member individually and try to comment their individual needs."
