I work for an entity called eBay Canada Limited, which is a Canadian corporation. We collect and remit taxes on the services that we provide. On the fees that we charge our sellers, which is how we make revenue, we collect the sales tax and that's remitted to the federal government.
We also give our Canadian sellers the ability to create tax tables. They also can apply the appropriate tax based on the Canadian jurisdiction, so that in fact, they can also collect and remit taxes on the sale of goods.
