Just as a practical situation with regard to your last question about cellphone number numbers and email addresses, people are wanting to keep these for life. You now can take your cellphone number anywhere in Canada and keep it. It'll go with any other carrier for the rest of your life if you want. Your information has to stay at the original carrier and at your new carrier. That's how it works. Your email address and that information you want to keep as your email address has to stay at the original email provider and your new email provider, however it goes. There's a practical application to this consent idea.
