The Canadian passport may look like just any ordinary passport. But when exposed to ultraviolet light, also known as blacklight, you’ll be surprised to see secret designs hidden in the pages of this travel document. Redditor chachichachichicken shared images of the passport’s designs online (both in regular light and with a blacklight). These images include famous Canadian icons such as the Parliament Hill, Niagara Falls, and the Fathers of Confederation. For those who are wondering what these UV-enhanced images are for, Canadian immigration officials said they are not just for aesthetic purposes. They also help separate authentic passports from the fake ones.
