Yes. I think a private company would be able to have enough evidence, if they have the electronic address information. They would be able to identify the fact that this is a Canadian using a Rogers, Bell, or TSP account. They can note where the account is being held and can seek a court order to say that they need to collect further information and evidence on this in order to defend their contract, or the law in this case.
