Yes, there is an extra form to fill out. it has nothing to do with your PAL application - its merely a confirmation that YOU are applying in YOUR name and not for someone else.
I went to the central station in Laval, on Chomedey boulevard. THe lady constable (very cute and young) came out to the lobby, asked for my drivers licence, checked my papers quickly, then signed and stamped the receipt and I was done.
She knew what to do, was not rude or abusive, and they do not check the RCMP forms - its not their mandate. They are just there to indentify YOU as the applicant.
We even talked for a few minutes about their target practice qualifications. So it was all good. Be polite, and cooperative and it will go smoothly.
