I suppose there are two potential approaches to that. One is simply the provision that in the minister's opinion there are emergency circumstances, and it would be part of the minister's discretion to determine whether there are indeed circumstances. It would be possible to actually add a definition of emergency circumstances into the bill.
In our brief, which unfortunately isn't translated, we do footnote that there is an existing federal regulation that defines emergency circumstances. We suggest you look to that for guidance. In our brief we state that the reduction of carbon dioxide emissions from coal-fired generation of electricity regulations actually includes the definition of emergency.
