The young person, charged with second-degree murder, applied for bail.
The Crown sought detention on the secondary and tertiary grounds.
The court found a substantial likelihood that the young person would commit a serious offence if released, given his prior criminal record and history of violence while in custody.
The court rejected the proposed plan of release, finding the proposed sureties unsuitable and incapable of providing adequate supervision.
Bail was denied and the young person was ordered detained in custody pending trial.
