This is a pilot project only for Montreal applicants, but why did have they made you go through this pilot project?There is a pilot project in cic which is extended until oct 31,2018 They are changing the process in a convenient way check this link https://www.canada.ca/en/immigration-refugees-citizenship/news/notices/validate-permanent-residence-within-canada-extended.html. I think those who who have decision made before oct 31 will receive the COPR appointment which is you need to go to local office to have final interview then after the interview visa stamping.
So i think they are trying to remove sending passport via canada post (inland applicant)
Which province are you in?
