I wouldn't have the number with me. Last year there were, I believe, four or five authorizations. They are related to the class of activities that risk incidental interception, as when you're targeting a foreign target who may be in conversation with somebody in Canada. That's when you need an authorization, and it has to meet a number of criteria in the act that are spelled out there, such as that it has to be a foreign target and that you couldn't reasonably obtain the information in another way, and it has to have foreign intelligence value. The minister has to be satisfied that those conditions are met, and then the commissioner reviews those authorizations and assesses whether our activities have complied with them.
He also reviews, as you'll note in his report last year, all of the private communications—so that involves a Canadian on one end—to make sure they were used in compliance with those conditions.
