This is nothing new, this process has been in place for a long time. You can either goto the border and flagpole or land in a local CIC office. The only downside of landing locally is you might need an appointment which could take a while.
I think they just changed the process...and now instead of going to the border...you will have to do your landing at CIC office on the scheduled date...
Please share your experience after you become a PR..
