From a transparency perspective, the decisions around an exemption do have to be published in the Canada Gazette, so there is an accountability mechanism there in terms of making the public aware of a decision by either a minister or the regulatory body.
From an appeal perspective, ministers can always change their mind. More importantly, from a flexibility perspective, a minister can put conditions on the exemption. The exemption can be time-limited. The exemption can be a partial exemption. I don't want to leave the committee with the impression that it's a carte blanche. But the appeal mechanism would be to the decision-making body itself.
