AL is just starting to make its way into Canada. I've looked into it but for right now it's not as well known. The best reviews sites that we use are YellowPages, 411 directory, government directory among a few others. By far the best reviews come from Google+ when combined with Google Ads. These reviews are linked directly with the website and must be done through a Gmail account. This makes it more difficult to post fraudulent reviews due to the amount of work that it takes (i.e. setting up a new email just for posting reviews).
