sarahjamielewis, Canadian Christmas Canon is a little bit of a mess. In 2013 the Harper government granted Santa and Mrs Claus a set of e-passports establishing in the press release (https://www.canada.ca/en/news/archive/2013/12/all-santa-wants-christmas-is-an-epassport-805089.html) that they were Canadian Citizens.
This year, the Minister of Immigration announced he had granted "a temporary resident visa to a foreign national" widely attributed to be Santa - implying that at some point in the last decade Santa had lost his Canadian Citizenship or that the visa was granted in error.
