To get back to the OP’s question, it’s not enough just to ask if other countries require ID to vote. The follow-up question is “what kind of ID? How hard is it to produce ID?”
From the discussion on this thread, it sounds like the voter ID laws in the US need government issued photo ID? is that right?
If so, that’s quite different from the situation in Canada. Yes, we need ID to vote, but there’s a huge range of ID that a voter can use, designed to make it easy to show who you are, and also to respect the constitutional right to vote.
Here’s the list, from the web-page of Elections Canada (a non-partisan agency):
[QUOTE=Elections Canada]
There are three options to prove your identity and address:
1) Show one of these pieces of ID
• your driver’s licence
• your provincial or territorial ID card
• any other government card with your photo, name and current address
2) Show two pieces of ID
At least one must have your current address
• health card
• Canadian passport
• birth certificate
• certificate of Canadian citizenship
• citizenship card
• social insurance number card
• Indian status card
• band membership card
• Métis card
• card issued by an Inuit local authority
• Canadian Forces identity card
• Veterans Affairs health card
• old age security card
• hospital card
• medical clinic card
• label on a prescription container
• identity bracelet issued by a hospital or long-term care facility
• blood donor card
• CNIB card
• credit card
• debit card
• employee card

We accept e-statements and e-invoices. Print them or show them on a mobile device.
3) If your ID does not have your current address, take an oath
Show two pieces of ID with your name and have someone who knows you attest to your address. This person must show proof of identity and address, be registered in the same polling division, and attest for only one person.

Note that this list consciously makes it possible for low-income people to prove their ID: a letter from a soup kitchen counts. Elderly? Bring your pills and your health card. Student? letter from your university residence. Aboriginal? ID from your aboriginal group.
So saying that Canada requires voter ID does not mean that the impact of voter ID laws is the same in Canada and in the US.
