As I remember, the Income Tax Act is one of the pieces of Canadian legislation with the most privacy protection, because it is very sensitive. When we give our information to the income tax authorities, we want to make sure it's used for strictly income tax purposes. So it's in that spirit that we worked with the director general of elections and the income tax people to say that if the information was to be shared, Canadians should be informed and they should consent to it.
