The Ambassador Bridge company has won a legal battle, but the City of Windsor is appealing.
The quasi-judicial property standards committee ruled Monday that the city's orders to repair 114 boarded up houses be changed to orders to demolish.
Mayor Eddie Francis said the city will appeal to the Ontario Superior Court of Justice.
"We believe very strongly that the property standards committee overstepped their jurisdiction, considered issues that otherwise should not have been considered by the property standards committee," Francis said.
Coun. Ron Jones represents the Sandwich area where the empty homes are located.
"I'm concerned about what could happen tomorrow, but my understanding is that our legal counsel has sent a letter saying, 'don't go out and demolish properties tomorrow. You don't have a right to go out and demolish properties, just because this particular commission have indicated that you have a right to do some things,'" Jones said.
City solicitor George Wilkki told CBC News the Ontario Superior Court of Justice would have to uphold the committee's decision before the bridge homes could be torn down.
"There's issues as to whether the city itself has the jurisdiction to change an order to repair into an order to demolish, whether the committee can order demolition that is then contrary to the city's demolition control bylaw," Wilkki said.
It's unclear how long it will take the court to rule on the case.
