The challenge with these numbers is that many of the figures are just unknowable—for instance, the number of individuals who are born outside Canada to Canadian citizens. The federal government does not have access to that number—indeed, no government has access to that number—whether they were born before 1947, between 1947 and 1977, or after 1977. We can't possibly know that. There was no obligation, and there is no obligation, for Canadian citizens to report their foreign births to the federal government.
We do know those cases who have approached us. We're aware of those individuals. We're working through those cases and trying to process them in as expedited and facilitated a manner as possible.
