"The man was found without vital signs early this morning," the CBC's Ivy Cuervo reported.
"We know that there was an incident yesterday, a fight that broke out. But it was an overnight party,it seems, that may have led to an altercation," she said
Part of the area was closed off for a police investigation and the coroner and a forensics unit was on the scene at the apartment above a store front at 2889 Keele St., just north of Wilson.
"This premise behind me has been operating as a booze can and there were several people in the premise at the time," said Det. Sheila Ogg of the Toronto Police Homicide Squad.
Most of the people inside were from Toronto's Spanish community, Ogg said, adding that police "are urging people who were there last night to give us a call and let us know what they saw."
Police also said the operation was a small one, but that there could be at least up to 30 after 3 a.m.
Cups, beer bottles on ground
Cuervo said there were "a number of cups including beer bottles on the ground" with police markers identifying them as clues.
A 911 call about the shooting came in at around 7 a.m.
"By the time EMS arrived at the scene they found a man about 30 years in age who had obvious gun shot wounds."
One neighbor told CBC that the man who lived in the apartment was a new immigrant to Canada, possibly from the Dominican Republic.
"We know that the tenants who live in this apartment are a family – a husband and wife and a child, but that child was not there at the time of the incident," Cuervo reported.
A gas attendant who works nearby told the CBC that the man who lived in the apartment often dropped by to buy lottery tickets.
So far, no suspects are in custody, police said.
