Fallout from Montreal's water meter contract continues to make waves at city hall.

There are conflicting reports as to how much it will cost taxpayers to get out of the deal.

Mayor Gerald Tremblay says that if the SQ investigators find any evidence of collusion in regards to this contract, it is unlikely the city will have to pay any fees.

But until that investigation is complete, the mayor insists the cancellation cost will be minor.

"There's a clause that says we can rescind the contract with one percent, so that's three million dollars," said Tremblay.

Projet Montreal's mayoral candidate Richard Bergeron expects the exit tab to be closer to $25 million.

"Come on, where are you living Mr. Tremblay. What do you know about this contract? You are so naive, it's incredible," said Bergeron.

Meanwhile an Angus Reid poll published in La Presse shows an increase in voter dissatisfaction with the Tremblay administration, with Louise Harel of Vision Montreal pulling ahead by five percentage points.

Former Vision Montreal leader Benoit Labonte says a Harel administration would have dealt with the problem differently.

"When you're mayor of Montreal, the law is very clear you have a responsibility to verify and control your administration. It's in the law," said Labonte.

Genieau, the company that was supposed to carry out the contract, says they need to discuss the matter with their lawyers before they can say how much they'll charge in cancellation fees.

They also say the contract can only be cancelled by a city council vote.

Vision Montreal is calling for an emergency meeting next week, but the mayor's office is not convinced that a council meeting is the only way to sink the contract.

The city's legal department is currently researching the best and cheapest options for getting out of the water contract.
