As was widely anticipated, Quebec's Bill 62, banning face cover in the realm of public services, will be legally contested: by an individual niqab-wearing woman, supported by the CCLA and the National Council of Canadian Muslims. Prime Minister Justin Trudeau is considering how his government too may "weigh in" on the challenge.
Amongst the (anglophone) chattering classes a consensus has formed that the challengers will win on constitutional grounds, in that women have a Charter right to dress as conscience dictates.
"Dress." There's the constant rub. I hope the court will see the difficulty here. While I make no comparison whatsoever as to motivation or purpose, to me, the niqab is no more an article of clothing than a KKK costume. Both are cause-rooted uniforms, draped over clothing, designed to embody a strong message.
