Ottawa was tricky because the jurisdiction belongs to the OPS, which fumbled the entire situation from beginning to end. It wasn't entirely clear if that was intentional either. The RCMP (federal) was brought in to break up the protests, but there was a lot of stone walling from the conservative provincial government.
There is also a world of difference between an organized protest with a specific purpose drawing awareness to a cause and thousands of people using commercial vehicles to hold a city hostage with no purpose or agenda other than a bunch of angry people unleashing their rage on the cities populous.
