The government defended its decision, with PC MPP Matthew Rae stating that allowing a judge to vacate an elected official’s seat would be unprecedented in Canadian history.

The Ford government passed Bill 5 in June, which allows it to create special economic zones where municipal and provincial laws can be suspended.
