Delay in processing and student permit

[Adzosophia]

My son has a student visa to study in Canada. On arrival he presented all documents as required but was given a 3 month temporary permit. He's re applied for a student permit since December 2021 . But still doesn't have his permit. His siblings we came after him have all being given their permit and l am responsible for their education sponsorship

Had his other visa expired? Are his parents on WP or study permits?
