The largest user of local water might not have any say over whether fluoride should or should not be in the system.

So says a legal opinion obtained by Sarnia city council. The document, from law firm Aird & Berlis, backs up a previous opinion received by the Lambton Area Water Supply System (LAWSS) board. A simple majority of muncipal councils who are members of the system can pass by-laws requesting the chemical be removed and it would have to be under provincial law.

The city of Sarnia, which uses the majority of water, would have only one vote. That is unfair said Sarnia Mayor Mike Bradley.
