Other commenters have noted that this is a provincial rather than a federal bill, but it’s also worth adding context that this was a hot topic in Canada’s 2015 federal election. [1][2]
This bill bans every "religious symbol", including a hijab. The niqab is, from my understanding, a full face and body covering garment, and most people would consider that different from what this bill targets. I don't think it is fair to say this exact same thing was a "hot topic" in the Federal election.
