A 19-year old man was airlifted to a Toronto hospital trauma center after he was critically injured in a shootout that left three others wounded with non-life-threatening injuries at an apartment building in Whitby, east of Toronto.  

Durham police said they had tried to piece together hints from public and were not able to gather a suspect description of the person who opened fire at 12:30 p.m. Thursday inside the apartment block located at 101 White Oaks Court in Whitby, Durham police Sgt. Nancy Van Rooy said as reported by the National Post.

Van Rooy said that the investigation was on its preliminary stage and it had not been possible to establish a suspect description or identify the suspect.

As officers visited every floor of the high-rise, knocking each door for possible witnesses and information, Van Rooy said that police were trying gather evidence leading to identification of the suspect.

"We continue to canvas the area looking for any co-operation from the public, and witnesses that can help further the investigation," CBC News has quoted Van Rooy as saying.

She said that the police investigators would be looking into any surveillance videos from the apartment building.

"Essentially the building itself is the scene," Van Rooy said to reporters.

"We have a number of leads we are following up on hoping to be able to further the investigation in a very short time span," she added.
