Well, this is a bit awkward. 
Difficult for Bill 62 to attack religious freedom when the niqab is not a garment required by Islam but a cultural lifestyle choice. 
This is a secular western society. 
Interacting with one another face-to-face is what we know, what we feel comfortable with and what we do. 
A niqab has no more place in the day to day discourse between people than a hockey mask. 
Quebec - and many other jurisdictions around the world- has rightfully drawn a a line as to how far they are willing to go with respect to cultural accommodation.
