Sure.
I'd like to return to your having pointed out that crown servants are actually considered residents of Canada. What that in fact seems to mean is that the employment confers this status: that you are in fact considered in law a resident of Canada. So it's actually the residency that becomes the determinant.
The question, then, is this: is it strictly for the employees or would that same premise of residency apply to family members of employees serving abroad? So if the child is in fact born abroad, but the parent is considered to be a resident of Canada, is there a consideration that the child of this employee who is abroad, but considered to be a resident of Canada, also be considered to be a resident of Canada?
