I suspect that Infrastructure Canada and the federal government do not necessarily want to impose some kind of accounting practice on a province. I think that's what the DM of Infrastructure Canada said in response to this committee a couple of weeks ago when he said that every other week he is in contact with provinces to have some reports back. I don't know exactly the mechanism he's using, but he certainly mentioned that on the record.
