This is an issue that we definitely grapple with, not only in Hong Kong but in other places.
That estimate of 300,000, which is very widely quoted, is based on survey data. It's based on a survey that was done 10 years ago, commissioned by the Asia Pacific Foundation of Canada. It was a rigorous telephone survey done by polling professionals. That's the basis of that estimate.
It's not based on the number of Canadians who are registered with us. Only a fraction of Canadians who go abroad register with us online. We don't have a way of tracking Canadian citizens who live in other countries if they don't identify themselves to us. That's why, from time to time, we would make a special effort or take advantage of something like the Asia Pacific Foundation's survey.
What I can say is that, in the time since that survey was done in 2010, we've seen the rate of Canadians renewing their passports in Hong Kong actually grow. In the five-year period from 2012 to 2017, the number of Canadians renewing their passports was about 20% higher than it was in the five years before the survey was done. That would lead us to conclude that the number that was there in 2010—and the survey estimated conservatively about 295,000—is probably about the same or more today.
