Hi david26,
I had submitted a request for CAIPS notes as well and had neglected to include a $5 cheque. One of the people that process them called me up 1 or 2 weeks after I had sent it to request the additional cheque.
HOWEVER, on the phone, she told me that if my husband was IN Canada, it is under the Privacy Act and would be free (even if he isn't a citizen or resident). But since he is out of Canada, I had to pay $5. If I understood correctly, if you are inside Canada, I believe you DON'T need to include $5 . If anything they will contact you quickly enough about it requesting it.
