Fabio Joel De Mello, 27, is accused of hitting another man over the head, after an apparent dispute near Dundas and Lisgar streets in the early hours of June 28.
The victim, Daniel MacLeod, 22, was walking home from a bar when police say he was approached by a man and a woman.
A verbal altercation ensued and MacLeod was struck in the head with a weapon, police say.
MacLeod is now clinging to life in hospital and has subsequently undergone surgery, suffered two strokes and is fighting pneumonia. He remains in a coma and doctors are not sure if he will live, or how he will fare if he does survive.
The victim’s cousin, Sonny Day, told CBC News that doctors say MacLeod “may not make it.”
But Day said the family is “still hopeful that he’s going to pull through.”
Toronto police arrested De Mello on July 7, more than a week after the assault occurred. He has been charged with aggravated assault.
De Mello was granted $100,000 bail in a Toronto court on Tuesday. He must stay away from bars or establishments where alcohol is the primary product sold and he cannot be in possession of any firearms.
He is due to return to court on Aug. 7.
