The boy's stepmother was handed a life sentence with no chance of parole for 13 years.
Garfield Boothe and his wife Nichelle Boothe-Rowe were both convicted of second-degree murder in April by a Brampton, Ont., jury after 14 hours of deliberation.
Shakeil Boothe — who came from Jamaica to live with his father in 2009 — was regularly beaten, deprived of food and chained to his bed in the months before he was found dead in his bed in 2011.
Jurors were told he died "minutes to hours" after a savage beating that left him with a black eye, bruised head, re-fractured rib and internal bleeding.
The guilty verdict had carried a mandatory life sentence with no possibility of parole for 10 to 25 years but the exact length of the parole prohibition was what was to be determined today.
