Study application for a similar level of education

[Earth2Mars]

Hi

I'm wondering if immigration considers applicant's degrees in approving a study permit.

If I have a computer Engineer degree, and apply to do a certificate or a diploma in computer science or engineering close or part of that degree

Could they deny applicant based on that? Program has coop, so employment pathway and canadian experience is the reason the applicant is applying to study in the same field.

Thanks
