When we see Paige's Canadian passport, it's written she is from Manikawi, Quebec. This town doesn't exist. It is probably a misspelling of Maniwaki, that does exist. Given that not many people will know about that I guess it was an unwanted mistake, but when you know it, it becomes a plot point where this passport becomes really important in the family escape.
