Elections Canada OKs wearing of niqab while voting

This is a bad idea. As the article points out there is an issue of validation of a person's identity if they are allowed to cover their face. Bringing another piece of ID or having someone vouch for you is not has fail-safe as physically showing your face to be checked against some piece of ID.

Yes, IDs can be faked, but that is much harder than taking someone woman's ID who has the same eye colour as you. Want to vote twice? Find a friend not voting, borrow their ID, and go vote again, but this time with your face covered. This is full of problems.

Political signs in Canada

Around town I have seen a political sign for the environment that says to vote for the environment next time there is an election. The sign has the line (roughly), "Please lower emissions NOW".

I don't know about you, but I would never imagine a political sign in the States wasting space on the word "please". This is especially true if you are going to put "NOW" in all caps like you are yelling it at someone for emphasis.
