We were in Montreal visiting friends last week and talked about this. It also applies to the somewhat large Orthodox Jewish community where the men keep there head's covered. I wondered whether it applied to the women some who wear scarves but most wear wigs (only the husband is supposed to see their natural hair).
I'll talk to friends and family who still live there, see what they know, which may not be much yet. But I suspect that although the enabling legislation has passed, they probably haven't ironed out how to apply any resulting regulations.
Makes you wonder about things though. What if head scarves become a fashion thing generally? How would they differentiate between a woman wearing a hard scarf for religious reasons and those wearing them for fashion reasons.
Seems like a pandering overreaction. The only real need to act, it seems to me, was with respect to full facial coverings and passport photos or driving license photos, etc. How many people does that actually affect? That is to say, are people's sensibilities really disturbed because their kid's teacher is wearing a necklace with a crucifix on it?
And as Alan pointed out, is there a difference between a regular beard and a religious beard?
