Yes, it's just a comment.
First of all, we are not automatically notified when a Canadian is arrested abroad. It's up to the Canadian to decide whether or not they wish to communicate with us. They have a right under the Vienna Convention to talk to their government through our mission abroad, but many countries do not, as a matter of course, advise us if a Canadian is being arrested. Our knowledge of who is abroad and whether they've been arrested really depends on the Canadians telling us that fact.
