Regarding crossing into Canada, I've crossed into Canada from MN frequently, because our family owns property up there. All of the border crossings have computer information at their fingertips, including ALERTS. I once forgot my passport, and they just went into their computer and used my DL info to find me. They also had my passport info IN THEIR COMPUTER. Highly unlikely anyone could cross with an endangered child, or without passports. (even if she were hidden) They would also check trunks etc, considering the missing child alert,
