The 19-year-old offender, who was 16 at the time of the offences, was convicted of multiple counts of robbery with a firearm and unlawful confinement relating to a string of convenience store robberies.
The Crown sought an adult sentence of eight years.
The court found that the Crown failed to rebut the presumption of diminished moral blameworthiness, noting the offender's complex trauma, impulsivity, and history in the child welfare system.
The court imposed the maximum youth sentence of three years, comprising two years in closed custody and one year of community supervision, along with a lifetime weapons prohibition.
