The accused was convicted of two counts of second-degree murder for the stabbing deaths of a father and son in their home.
The mandatory sentence is life imprisonment.
The Crown sought a parole ineligibility period of 20 years, while the defence sought 16 years.
The court considered the brutal nature of the offences, the vulnerability of the victims, the accused's background, and the impact of pre-sentence custody conditions.
The court set the period of parole ineligibility at 18 years concurrent on each count, commencing from the date of arrest.
