We had the same thing. Of course, in a border town many people are used to going across the border every day for shopping and visiting family. Many people have partners, and their relationships were damaged by this long border barrier.
One thing we saw as well was that many people who crossed the border and filled out their ArriveCAN would get emails two or three days afterwards. Nobody would say anything to them at the border, but two or three days later they would get emails saying that they had missed their first test and that they should be quarantining. Meanwhile, they'd been three days wandering around the community because nobody had told them anything about it. Then they were threatened with fines.
Did you have anything like that happening in your riding?
