As Madam Laflèche mentioned, for confidentiality reasons, whether an individual company pays or doesn't pay tax, that's their business with the CRA. I will say, though, that when we look at the size of the retailing that goes on in the e-commerce world, and when we think about how much money is out there, it's complicated to estimate, because a lot of transactions that occur are business to business. Businesses would buy goods online and get an input tax credit for it. There would be no revenue collected.
A lot of foreign businesses are registered for the GST and the HST because they have operations in Canada. They have online components and in-store components. For us to look at all the data and say what is the total amount that could possibly be collected by the application is very difficult, because of the circumstances as to whether an individual company is actually a registrant. They might be. They might be the owner of some of the things that they sell, in which case they're required...or they might be acting as an agent for someone else. The industry is evolving all the time. We've talked to people and they've said that they charge tax on some things, but not on others. To determine an estimate is quite difficult.
