Mr. Chair, the SIN card was never supposed to be a form of identification. It was never an identity card, so it doesn't contain any of the security features. Those who apply for jobs or need to produce their SIN numbers aren't required to produce it physically. It's one of these things that has reached its full use, as far as necessity. As such, the government has recognized that it's no longer necessary to issue these cards. We will cease to issue and produce and mail the plastic cards.
