Early Friday morning, a man went to a house in the area of Bathurst Street and College Street West.
Police say he got into an argument with another man inside the home and took a handgun out of his bag.
The assailant then "pointed the firearm and shot the male," Toronto police said in a Friday news release.
Emergency services received a call about the incident around 2:30 a.m, said Dave Viljak, a deputy commander with Toronto EMS.
He said paramedics transported a "young adult male" to hospital in serious condition. The victim had suffered a single gunshot wound, Viljak said.
Nerville Ferdinand, 19, of Toronto, is wanted in connection with the non-fatal shooting.
Police are asking the public for assistance in locating Ferdinand. Investigators have issued the media a photo of the suspect and describe him as:
- 160 lbs.
- With a short Afro haircut and brown eyes.
Police urge members of the public who spot Ferdinand not to approach him and to instead call 911.
"He is considered armed and dangerous."
