It's written down in guidelines that we give to our assessment officers, our citizenship officers, to those who are making these decisions.
So do they live here now? Have they lived here most of their life? Have they had a reasonable but mistaken belief that they are Canadian or that they were Canadian, in fact? It's the border babies example.
Then the overriding principle that guides the assessment is the issue of undue hardship. Does it pose an undue hardship for the individual to seek citizenship through the permanent residency and regular grant-of-citizenship process?
Those are the four elements we use. We try to use that to the best of our discretion and in the fairest way possible, on the basis of looking at cases we've seen previously in making a recommendation, positively or negatively, on a case.
