It costs $5. They won't send CAIPS outside of Canada. You could have them sent to a family member in Canada and they could send them to you. You can get them on CD in a PDF document that could be emailed to you.
And here is the link to the document you need for your CAIPS notes. http://www.cic.gc.ca/english/pdf/kits/forms/IMM5563B.pdf
On this form, leave "Requesters reference no." and "ATIP File No." blank. The reference no. is for agencies that request a large volume of information and you would not have an ATIP File No. yet because you've never requested anything before. Fill in your husband's name and birthdate and then in the box that indicates the $5 fee, check off "receive copies of the records" or "cd". Go down to the "Request for" section and check off CAIPS, NOT the VISA file as this will take much longer to receive. Write the city and country where the application is being processed in the Embassy name section and then your husband's file number which starts with a B. Fill in your Canadian address information at the bottom of the form.
You must also get your husband to sign and return the "Authority to Release Personal Information" http://www.cic.gc.ca/english/pdf/kits/forms/IMM5475E.pdf form to you and include it with the "Access to Information Request" form.
Send both of these forms and a cheque for $5 payable to the Receiver General of Canada to:
Citizenship and Immigration Canada
Access to Information and Privacy Coordinator
Narono Building
360 Laurier Avenue West, 10th Floor
Ottawa, Ontario K1A 1L1
You should receive your CAIPS notes 30 days after they receive the request.
