One man died at the scene and the other was taken to hospital, where he is expected to recover.
Three men were sitting on a park bench when someone approached them, talked to them and then opened fire. A man in his 30s was shot in the head and pronounced dead at the scene. A second victim was also hit by a bullet in the torso.
Police blocked off a large section around Bathurst and Dundas for about two hours as tactical officers and K-9 units searched for a suspect. Investigators say at this point they are still looking for the suspect.
Police are characterizing this shooting as a targeted attack.
