A$AP Rocky won't be getting wild for the night at a music festival in Canada -- the event organizers just canned the rapper over his alleged fan-slapping ways.
TMZ broke the story -- A$AP was charged with criminal battery last week for allegedly slapping a fan during a Philadelphia concert ... and the victim wants his ass punished in court.
AR was scheduled to perform at York University next Wednesday in Toronto -- but the school's student federation has now pulled the plug saying, "the event cannot proceed until this matter is resolved."
The organizers added ... their decision to boot A$AP does NOT mean they think he's guilty of getting slaphappy.
The alleged victim Lisa Wade called in to TMZ Live last week -- and said the slapping was no accident.
