We require photo ID and confirmation of address to vote in Canada. If you don't have a drivers license, you can use a passport + utility bill (something with your address on it). If you don't have any ID, you can have someone come with you and sign a "testament to your identity".
We had the lowest turnout ever for our last election (60%) and some speculate that it was because all of these rules having recently been put in place. I can see the validity of having the rules, but there needs to be better organization in educating people beforehand and having systems set up for those who may not easily meet all the requirements.
