A man in his 30s has died of his injuries after being shot in the chest in the Queen and Parliament streets area Monday evening, Toronto police say.

Police say the 31-year-old man was ambushed as he waited for an elevator on the fourth floor of an apartment complex at 285 Shuter Street.

“I’m not sure exactly how many times he was struck, but we know that there was at least the one gunshot wound obviously and that’s what led to his death,” Det. Sgt. Dean Burks told reporters outside the complex late Monday night.

He said a female who was waiting with the victim at the time of the shooting was shaken, but not physically harmed.

The man left the building and eventually collapsed on the sidewalk north of Queen Street.

Paramedics said they were called to the scene around 5:30 p.m. and transported the man to hospital in life-threatening condition. He was pronounced dead upon arrival at the hospital, police later said.

Burks said the victim – whom he wouldn’t immediately identify – was known to police.

He did not live at the complex and police are not yet sure why he was there, Burks said.

Officers are now canvassing the building to speak with residents who might have information about the shooting.

“We’re hoping to generate some additional witnesses through that,” Burks said.

Forensics officers are also combing two floors and stairwells to collect evidence, he said.

A handgun has been recovered from the scene and one or more suspects are currently outstanding, police said.

Burks said he could only offer a broad description of one suspect as a black male in his 20s.

He said they victim’s family has been notified of his death.
