Q: When will Siri be fully functional in Canada?

I currently use an iPhone 4S with iOS 5.1... I frequently use Siri to book appointments, read my most recent txt messages, etc... She works wonderfully for these tasks but she will not search or locate places, buissness in Canada. I am aware that Siri in Canada is a beta version, I am curious to know when with this change to a fully functional version?
