When I was working as a PI here in Ontario, our company was hired on a regular basis by clients whose property was going to be the subject of a protest . One example was the Hudson's Bay annual fur auction here in Toronto. The folks from PETA and their followers were expected to show up, and try to prevent buyers from entering the sales building. We instructed HB to file for an emergency injunction, to bar any protest on their private property. It was granted by the courts.
The building was about 150 feet from the public sidewalk, so it was easy to put in place barriers and park large trucks on the property as physical blockades. We stationed a number of our investigators who were equipped with video cameras on the property, including the roof. We had it covered. We also instructed HB to tell all the buyers to park three miles away, at a secured parking garage, then we brought them to the site in a armored bus. By doing this, we avoided the problems of protestors blocking a long line of private cars, and possibly damaging them, too. AS usual the bus took a lot of hits from eggs, paint bombs and stones, all of which we were able to record on video. No injuries.
The Toronto Police had their Public Order Unit there, but the POU stood back and only got involved when some people tried to cross the barrier lines. They were arrested for criminal trespass and removed to the jail to be processed photographed and finger printed, then released again. The video that we shot was later used by HB to sue PETA in civil court. HB won a sizeable judgement against PETA, which the courts enforced. The protestors were tried and found guilty of trespass, fined , and they now would have a criminal record in Canada. JimB.
