That's right; this FIPA permits Canada to also not disclose documents if it determines that it's not in the public interest. It allows Canada not to have public hearings if it determines that it's in the public interest not to do so. If that's not Canada's policy, why didn't we just specifically say all disputes filed against the Canadian government will be held in public and documents will be disclosed to the public, if that's our policy?
