This is kind of amusing: when you talk to Finance, they say the administrative fix is with the Canada Revenue Agency, and then the Canada Revenue Agency says, no, it's policy. Meanwhile taxpayers are caught in the centre, watching this tennis match between Finance and CRA. So it's not a very satisfactory response to say that we have to go and talk to the Finance boys and girls.
I take it, then, that really your answer is, “We don't know; we're not responsible.”
