Windsor Mayor Eddie Francis is vowing the city will do everything it can to secure the city's downtown Capitol Theatre.

The 80-year-old theatre was the site of a small demonstration Thursday denouncing the court ordered sale of the theatre's assets.

The theatre declared bankruptcy in 2007, and the city is currently engaged in a legal battle with the building's trustee and creditors.

A court has ruled the building should be turned over to the city because it has a valid mortgage to the property, however that ruling is under appeal.

The city had offered $300,000 to buy the theatre, but was turned down.

Mayoral candidate Rick Limoges and Ward 3 candidate John Liedtke were among those protesting the sale of assets.

Mayor Eddie Francis said the city offered $75,000 for the theatre's assets but that offer was rejected by the trustee. (CBC)The city of Windsor has offered to buy the assets, but the trustee said the $75,000 offered isn't nearly enough.

The mayor says the city is trying to work out a deal with the trustee, but is also in discussions with the University of Windsor to relocate some academic classes to the theatre.

"We're not going to run the theatre to lose money," said Francis.
