I did my landing today at Rainbow bridge. Arrived at the bridge by 7 PM then came back to Canadian border by 7:10 PM. Received my papers and asked me to go the other building. Inside the building, they took my documents and asked me to sit in the waiting area. There were 5 persons waiting there but I didn't ask their business. I was removing my scarf and coat but then other officer called my name so I kept my coat on. The officer asked the same questions listed in the COPR and answered back. He asked me to put my initials on the 2 questions and signed in the bottom for the 2 COPR. He filled some fields and dates and signed both documents. Stamped my passport and returned back my documents. It took around 5-10 mins max and I am done. Done linking the PR Card application also in my MyCIC account so I can monitor the status.
