Protests are supposed to be provocative. My understanding is that they have permits to protest outside the Christian Basilic. So long as they aren't doing anything illegal, I don't think it's a good idea to police how they protest. If we go down that road it's only a matter of time before another protest makes people feel uncomfortable and more restrictions are put in place.
You can't ban prayer while also standing up for free speech. I personally dislike religion in general, but it's part of the cost of free speech.
For your information, they absolutely didn't have permit for those prayers.
Why didn't they pray in front of their mosque if it is not provocative actions ? For what purpose ?
You should know that some muslims fanatics want canada to become a muslim country !
