Hi
I did my landind at Niagara Falls border in december'15 . Living in toronto and had no visa to go to U.S.
I drove to Niagara Falls border and crossed the border and asked an officer at the U.S. border . He was kind enough to guide me right direction and asked me turn around . At the Canadian border entrance i told the CBSA officer that i am here for landing and he checked my papers ( passport and COPR) , gave me a yellow slip . Parked outside the CBSA building and followed the instructions. Was called upon my turn , officer asked me 2 questions ( any criminal record and proof of funds) . Stamped my COPR and congratulate me on becoming PR .
Was in and out of the whole process in 45 minutes.
Good luck to you . pm me if you need further details
Thanks
