By banning religious signs you do the opposite of separating religion from the state, since the state is forcing people to hide any sign that the person is from a religious group.
There is also the problem that there is thousands of religions that may have their own signs how can you known all the religion signs and ban them? Also beards can be considered a religious sign should we also ban it or require a certain beard length limit just like peoole used to measure how short a women skirt is?
I hope this don't make more visible divisions between canadian. Right know most of the separation is shiwn online.
