May I take the liberty of summarizing what you've just said? Tell me if I'm mistaken.
Hydro-Quebec has created three distinct corporate entities and reports the profits of each one. You acknowledge that difference and you don't discuss the validity of their figures. You're telling me that, because a counterpart in another province does everything under the same corporate hat, because a single Crown corporation carries on three activities in a particular province, you find it too complicated to separate the various activities. In the case of Quebec, which separates them, you say you have nothing to say about the figures.
You refuse to grant the same treatment to Hydro-Quebec, whose activities are identical to those of Hydro One, because the other provinces haven't separated activities within their Crown corporation responsible for hydroelectric power production.
I think that's a constitutional aberration, not a policy question, as you just said it.
