It was fine as we had all the info needed, and English is both of our first/native languages. (some immigrants were having a hard time answering the questions that the border officials needed answering) We arrived and went through to the US no problems and then went back, with only about 2 minutes in the US border controls.
Coming into Canada was ok, the officer asked why we hadn't inland landed at Calgary or Edmonton, and we just said the CIC call centre said we could do either. He then said it's gonna be a long wait as a lot of people land on a weekend.
Went inside handed our paperwork to the next available officer and were told to wait in the waiting room/car and we will come get you when it's your turn to be processed.
2 hours later, immigration officer gets us, asks us a few questions hands us the completed COPR and makes us sign. Wishes us a good day and sends us on our way....
