When Freddie takes a picture of Gibby and the kid the sign next to him reads no photos though he either ignored the sign or forgot it was there.
When Freddy, Spencer, Gibby, Sam and the guide enter the production room for Fat Cakes, they are not wearing hair protection. This would pose significant health hazards during the production of the Fat Cakes, especially since Sam has long hair and gets close enough to the production line. As this took place in 2007, hair nets would definitely have been required.
Sam would have needed a passport to enter or exit Canada however given the fact she has a criminal record she should not have been allowed to enter Canada at all.
