If you are in Canada, before you get all excited and start blazing through Google Play trying to find the app, you should know that this is all speculation based on some apparently successful attempts to validate Canadian phone numbers using the Google Voice app. Also, while it cannot be found by searching Google Play, it can apparently be downloaded via a direct link (see our source links below) where previously it used to be restricted. There may be some other hoops to jump through as well.
Taking those issues aside for a few moments, a number of users in Canada are reporting that they have been able to validate their numbers on Google Voice. The process does not seem to be all encompassing though. The guys at MobileSyrup caution that many features are not operational even if you do manage to get it working. In all likelihood, you may still need a US number to establish before you can assign a Canadian number.
Is it a sign of Google Voice getting ready to tip its hat in the Canadian market? It is hard to say, but with what some of the folks are reporting they have been able to do, it is clear that something has changed on the back-end with Google. Taking into account that the Google Voice app can be downloaded, numbers can be forwarded to cell phones in Canada, and calls originated in Canada are getting routed to local numbers in Canada indicate that things are afoot in the great white north. If you decide to give it a go, make sure you have a rate plan that can withstand a bit of long-distance calling, since many rate plans on the Canadian carriers do not include long distance in many of their plans.
