There are several regulation-making powers in the act. Some of them are given to the minister, but it's usually for things like emergencies.
There's a list of Governor in Council regulations in section 30 of the act. That lists pretty exhaustively what the minister can prompt to make regulations about through the process of the Governor in Council.
The exemption power, as I mentioned, is in the Governor in Council. It's not something that the minister has the power to do. The minister can prompt that by making a proposal to the Governor in Council.
