What link from what site in Canada?
I am not sure if there is any special rule for Canadian citizenship applicants to get fingerprinted in Canada ( I doubt there is), but I know several people who live in the US who have obtained RCMP checks for other purposes by submitting finger prints to a RCMP accredited fingerprinting company. In fact in Canada too, you do not go the police, you go to a RCMP accredited fingerprinting company. They usually take your fingerprints digitally and send it to RCMP. Only a few do it non-digitally nowadays.
You will need to find an RCMP company in the country you are in.
