Perhaps I'll start. Then I can turn it over to Deputy Duheme.
I am aware that significant efforts were made around, for instance, exclusion zones, in that the Emergencies Act allowed police broader and more clarity to enact exclusion zones. You may have seen in the media that there were up to 100 checkpoints. It also enabled the police more clarity on restricting travel, so that if there was information that a convoy was on the way to Ottawa, it enabled police to turn that convoy around—so travel restrictions.
The issue of compelling tow trucks was a significant issue. Certainly, I can speak to Alberta, but another significant issue was, we heard, where tow truck operators were either threatened or intimidated and stayed away.
As far as your question goes with respect to it as a deterrent and whether people left the city of Ottawa, I'll turn it over to Deputy Duheme.
