We do have, obviously, a list of countries where visitor visas are required for individuals, and many others where folks don't need a visitor visa to come to Canada. What happens in that set of circumstances, for people who do require a temporary resident visa, is they make the application overseas, now sometimes through those visa application centres, and the screening is done overseas to ensure that we have medical and admissibility screening, etc., in place and that the person is a bona fide visitor, that they actually will return to their country of origin at the end of their period of authorized stay. So that's the visa that gets printed and put in people's passports.
But the final decision on admission, visa requirement or not, is made by a border services officer at the port of entry, where they will also engage in an examination and go through the information they have available to them as to that admission decision for people to come into Canada.
