The Grand Sheik is free to interpret his religion as he see's fit and others are free to agree or disagree. I am Christian and I disagree with the Pope on many points. I am free to practice my religion as I see fit and this right is protected by the Charter whether the Pope agrees with my interpretation or not.  And I actually have taught women wearing Niqab's in Toronto and Niagara for over a decade now and have never once felt that the niqab was a barrier to our interactions or their integration. I was able to look into their eyes and have a conversation just fine. Most people speaking on this issue have probably never once even spoken to a woman wearing a niqab. Try saying hello, you'll be surprised by the response.
