Reading about the Canadians who were refused entry due to mental health was very disturbing. I wonder if there is a way we can know what records border control has on us? It's possible they just have a note that you were arrested and you got pulled into the office because your answer didn't match their records. I suspect there is some kind of flag next to my name because I am stopped and searched frequently since traveling with someone who gave the wrong address - he had one thing on his license but had recently moved.
