When I landed at YVR, I had filled out the form on the ArriveCan app. It saves your information and to complete the final step, you must enter a token number. The token numbers were printed on big cards taped onto each of the desks where people were filling out the paper forms. Once entered, it gave me a confirmation number which I had to show to a screener before they would even let me in to the immigration area. So before even getting to the point of either the Nexus or regular kiosks and the lines to see CBSA. All of that happens pre-CBSA and way before the Customs form hand-in.
