EMS rushed the man to the Sunnybrook trauma centre, where he later died.

It is unclear what the nature of his injuries were.

Police were called at around 2:30 a.m. after reports of "unknown trouble," said Toronto police Det. Scott Whittemore.

During the Tuesday news conference, he told reporters that officers had arrested a male suspect in the case. 

Police haven't laid any charges against the man, but were still questioning him on Tuesday afternoon, Whittemore said.

Investigators are still working to identify the victim, who "appears to be about 40 to 50 years old," Whittemore added. 

A post-mortem was scheduled for Tuesday afternoon, he said. 

Police also seized a Ford truck as part of the investigation and continued to canvas the neighbourhood for potential witnesses on Tuesday.

Whittemore also asked residents and business owners in the area to provide police with surveillance footage from Tuesday morning.

"We would like to have a look at their video," he said. 

The detective wasn't able to confirm reports that the firing of gunshots led up to the victim's death.

"There has been reports, but we have no confirmation of gunshots," he said. "That's going to be part of the investigation."
