Well we will have the usual group start posting that this is unconstitutional. Alas, Quebec has never signed onto the constitution. Besides this is a public safety issue too. Men can dress up in those things carrying guns, they can also get caught in the moving parts of machinery and hurt the person wearing the getup. In fact some poor woman got her head scarf caught in an escalator in a Montreal subway and was choked to death. 

Wear your religion's getup in your church or in the home but not in public where things are supposed to be secular.
