That would be more of a difficulty. If they're accompanying a Canadian spouse abroad, that would fall within what I think should count for citizenship, because that's within the permanent residency rules.
Mr. Tabbara, what you're suggesting is that if someone is a Canadian permanent resident, goes abroad, works at a foreign university for a number of years, and then applies for citizenship, that person is actually at risk of losing their permanent residency because they're working abroad, but not for a Canadian company. We'd be in a situation where they wouldn't even be eligible, and they would be at risk of losing their permanent residency. Forget about citizenship. They can't even keep their permanent residency.
