Employees with Amherstburg police who do not wish to join Windsor police will receive severance.
An arbitrator has ruled employees are entitled to four weeks per year of service.
Police Board Chair Bob Rozankovic says exact numbers are still unknown but believes up to six could take severance packages.
He says the packages could cost the town up to $2.5-million.
Rozankovic says there will be a cost to taxpayers in Amherstburg.
"Quite honestly we're disappointed that some people have taken somewhat of an irresponsible track stating that no there would not be any severance and that was it, we never felt that," says Rozankovic. "As to how much it's going to be, honestly we can't answer that."
He's not surprised with the arbitrator's ruling.
"We did get the ruling this morning where the board has continually for months on end spoken to the very real potential of severance, that potential has now turned to a reality," says Rozankovic.
Rozankovic says employees are getting their employment offers from Windsor police on October 27th.
"They will have two weeks within which to response to those employment offers and once we know that information then we can nail down some numbers that will be valid," says Rozankovic. "At this point we're staying with an upper limit of two and a half million."
Mayor Aldo DiCarlo and Windsor mayor Drew Dilkens signed the 20-year contract last week.
The change was approved by the Ontario Civilian Police Commission in July.
The switch is expected to save the town $570,000 a year and will go into effect on January 1st.
