What we see varies from country to country, For example, there were figures that the Pittsburgh summit cost around $18 million. That was largely for additional services that were needed. If you tallied up all of the security services needed for that summit, for example, those were probably around $90 million. That would be the total summit costs in terms of security.
Certainly there's a reason I alluded to that earlier, and why Canada has to spend more money on security. In terms of these summits being an outlier, the question was why the figure was so much higher and whether it needed to be. From the studies we've done, the costs seemed higher than other summits hosted by countries that are more comparable with Canada. But certainly there's a reason for the numbers being significantly lower in particular countries.
