Plzz help!! I arrived in Canada in march with two permits (study permit and co-op permit) . So when i go to Service-Canada for my SIN number , i show them my Study Permit only first and they said their is some problem( they can give my sin number i have to go back to airport to get it correct (note it does have the work condition on it )......but then i show them my CO-OP permit and it works (i got my SIN number on COOP permit) .........So my question is that should i go to Airport Immigration to know why i dont get SIN number on my Study Permit and does this can cause problems for me in future........( It may be a nonsense question because i overthink too much :-( plz reply anybody
