They're planning a town hall meeting Wednesday to try and stop a request for proposal to select new operators for Casino Niagara and Fallsview Casino.
Even though the province has said no, Niagara Falls Mayor Jim Jiodati, Region Chairman Alan Caslin and Niagara Falls NDP MPP Wayne Gates say they won't stop.
Diodati telling post media they want to send a clear message that jobs in Niagara are a top priority.
He says they won't stop until they're able to correct a flawed process.
Up to 1,400 jobs could be affected.
OLG expects to announce the successful service provider in the summer of 2018.
