As of April 2009, self-serve stamping machines are available during regular office hours in all of the tax services offices. When taxpayers drop off original documents to the Canada Revenue Agency and need proof of delivery, they can simply bring a photocopy and stamp it using one of these convenient and easy-to-use machines. Also, taxpayers can send their information through regular post, registered mail, and courier service.
