No, we don't.
I guess probably Radio-Canada/CBC itself would consider that the Access to Information Act needs to be interpreted generously, not limiting. So therefore I don't see any relation with commercial.... Because if they were to raise this, they would raise it all the time. And as I've been using as an example, a fleet of cars would all eventually be in commercial matters. So you would raise and use commercial matters to just say no to all questions.
