As I said, we cannot know exactly how many foreign electors voted. The numbers I have here indicate that 60,000 electors voted under group 1—Canadian Forces electors, electors residing abroad, and incarcerated electors—and the numbers can be quite low. For example, in Prince Edward Island, the number was only 317, and in Yukon, it was only 97 electors.
So, if you remove group 3 from that, which is electors residing abroad, you end up with groups 2 and 5—Canadian Forces electors and incarcerated electors—that can be quite low.
