The NCCM is the same group that provided input to the TDSB that resulted in a definition of Islamaphobia calling any criticism of Islamic culture or politics "Islamaphobic" - the TDSB called it an accident... right. Assertive political Islam is a threat to Canadian values of gender equality, freedom of expression, and freedom of sexual orientation - they encourage regressive cultural practices that are synonymous with authoritarian regimes all over the world, without exception. In Canada the niqab is about freedom and modesty but everywhere else in the world, it must be worn under penalty of lashings or worse, go figure. 
The reason the niqab is not common in Canada is because Canada has evolved into a modern civilized progressive country. The niqab is only common in countries that are regressive, misogynist, and authoritarian - there are no exceptions. Canada isn't different than countries with the niqab, Canada is civilized, period.
