The Bloc Quebecois says wearing the niqab, or the Muslim full face cover, is a problem because of the message it delivers.
A new ad that the party has uploaded to it's Facebook page criticizes NDP leader Thomas Mulcair for his support of a woman who wants to wear a niqab when she is sworn in as a Canadian citizen.
The ad sports an image of the House of Commons as seen through a niqab.
It reads: "Should you have to hide your face to vote NDP?"
The BQ Facebook post says the party believes that the face must be uncovered when becoming a citizen as it should when we vote.
