if you know someone who can order the notes on your behalf from Canada, you give them the consent using this form
https://www.canada.ca/content/dam/ircc/migration/ircc/english/pdf/kits/forms/imm5744e.pdf and they can order on your behalf... Usally GCM/CBSA/CSIS notes are free to order for someone who resides in Canada.
GCMS notes advanced will provide you the copy of the documents you uploaded and correspondences you did as well, as part of your application along with the case officers notes...(which I think is an overkill)
