I think you mentioned a very good word here: “re-educate”.
From personal experience, after the restrictions were lifted, my family visited Switzerland. My mother, being 65 years old, had trouble filling out the ArriveCAN app. However, I spent about 10 to 15 minutes of my time teaching her how to go through the process.
Yes, this may delay the process of the lineup, and the shortages in the CBSA may not address the issue of needing help with technology that some people experience. However, if this is to protect Canadians, do you feel that the extra 15 minutes of individuals' time to use that app to make other Canadians feel safe is a necessary step to move forward?
