The city has decided not to appeal a judge's ruling — clearing the way for a byelection for councillor in Ward 9 and another for school trustee in Ward 4.
An Ontario Superior Court Justice ruled last month that the vote in the riding during last year's municipal election showed several "irregularities" and should be held again.
The incumbent in Ward 9 is Maria Augimeri who won the riding by just 89 votes over challenger Gus Cusimano.
The challenger took his case to court. His lawsuit focussed on the missing signatures of electoral officers on 426 of more than 1,100 forms that are used to change the voters list on election day.
Cusimano argued that not only were many of the forms not signed, voter identification was not checked in some cases.
The judge also found voting irregularities in Toronto District School Board Ward 4 where Mike Sullivan lost to incumbent Stephanie Payne by 56 votes.
The city issued a news release on Friday saying "[a]fter careful consideration, Toronto City Clerk, Ulli Watkiss, has decided not to appeal the April 21 decision by the Ontario Superior Court of Justice which declared the election results invalid for City Council Ward 9 and TDSB Ward 4 [City Wards 7 and 8] and ordered by-elections for these two offices."
The byelections will be held on July 25.
"The decision to proceed with a by-election and resolve this matter as quickly as possible is in the best interest of the public, the individuals directly affected, and the workings of Council," said Watkiss in a statement.
Nominations for the openings will be accepted until June 10.
