Since so few muslims do this, I doubt it is "targeting muslims".  It is targeting something that makes a lot of people uncomfortable.  I understand there was a poll just out that 68% of Canadians are in favour of this being a national law rather than just Quebec.
Wherever I go in the part of Canada I'm in, I see a great many Muslims every day.  Muslims that are showing their faces.  Sure, they may wear a covering over their hair, which is fine, but I am also not seeing them fearful.  In fact, I am seeing them completely comfortable.   I treat them just like anyone else.  Wearing something like a hockey mask or a bhurka inside in Canada is something that's not needed here, it just causes unrest and makes people uncomfortable.  I don't understand why people can't get that.  It is not a religious thing at all.  If it were, the other types of head coverings would be banned too, wouldn't they!  But they aren't.  There wasn't a law against it before because people weren't doing it.
