It happened in St James Mews, off the Antrim Road, around 9 pm and the PSNI say two men entered a house and attacked the victim.
The 53-year-old injured man is in a serious but stable condition in the intensive care unit at the Royal Victoria Hospital in west Belfast.
It is understood he sustained a number of fractures in the attack and has undergone emergency surgery.
Assistant Chief Constable Stephen said: “He has quite severe injuries.”
It is claimed the victim had been under threat over recent months from dissident republicans.
The chief suspects for the attack are Oglaigh na hEireann (ONH) who have been behind a spate of shootings and murder bids over recent months.
