According to the estimate of the Canadian Council of Muslim Women, there are 10-15 niqab wearing women in Quebec.

If we extrapolate to all of Canada, there would be between 100-200 niqab wearing women in all of Canada.

Therefore, 81 women would  represent a significant proportion of the total number of the 100-200 estimated niqab wearing women in Canada.

On the other hand,  over 5 million people voted for the Conservatives in the last election. So obviously 81 out of 5,597,565 people would not be significant in that case.

Anyway, as I said, I'm just quoting Dr Lynda Clarke who was commissioned by the Canadian Council of Muslim Women. 

You should report your concerns to the CCMW. Tell them to unpublish their report because you know that it is wrong.
