I think Catherine Porter did a good job with her article. Yes, the title of the article can be interpreted as a blanket accusation that Canada is a police state but it can also be seen in the context of the G20 inquiry she attended where witnesses gave first-hand accounts claiming that our police were indeed unaccountable and out of control on a number of occasions. The true test of police restraint and accountability is how they behave when they are assembled in great numbers and have almost unlimited powers of arrest. For those who were unjustly trapped, abused and detained in such appalling conditions, Canada was indeed a police state. That state of affairs was only temporary but if it happened once, it could happen again.
You can attempt to redefine what constitutes a police state by trotting out all sorts of examples where police in less advanced countries have behaved far worse but that doesn't change the fact that, if those witnesses are telling the truth, civil liberties and basic freedoms in Toronto were arbitrarily suppressed by the police, some of whom broke the very laws they were assigned to enforce. There will always be abuses. So we need to investigate these claims to make it clear that we won't tolerate this kind of police behaviour.
