When Canadians are detained abroad there is international law, the Vienna Convention of 1964, that applies. The Convention has been signed by Canada and 174 other countries. Under article 36, a country is entitled to be informed by the host country that one of its citizens to have access to the individual.
So that's really where we start from. If we find out that a Canadian has been detained in a foreign country, the first thing is to ask the authorities for access to that individual. And if we don't get access, of course, then we use the tools of diplomacy, whether it's diplomatic notes, phone calls, or representations.
Where we run into difficulties—and my colleague alluded to this in her statement—is when the person is a dual citizen. We try to do a lot of outreach to Canadians who have citizenship in other countries. If you look at the statistics, approximately 250,000 people immigrate to Canada every year, grosso modo. Within three to four years, the vast majority of those people get Canadian citizenship, but that doesn't mean they lose their other citizenship. They are de facto dual citizens.
