Frances Nunziata voted to fight the province over the Conservatives’ plan to reduce the number of council seats to 25.
Doug Ford’s party had cut the size of city council in half, midway through an election and without any warning.
City Council voted on Tuesday to go to court and restart the election process, in the unlikely event they win the case.
Frances Nunziata has been inconsistent on the issue. She supported the plan when it was first announced, then said it shouldn’t have been announced in the middle of an election cycle.
Frank DiGiorgio, who is also running in the new Ward 5, voted against going to court.
