The city of Dorval, Que. wants Air Canada and a contractor it worked with to repay it for money lost when it had to ban drinking water on its territory.
The city said the airline and a private contractor at Trudeau International Airport were responsible for accidentally connecting a reservoir full of stagnant water to the city's drinking water two weeks ago.
During three days, a city-wide water ban forced residents in the community of 17,000 to rely on bottled water, although city gave out four litres a day per resident at distribution centres.
Mayor Edgar Rouleau said Dorval has already sent a lawyer's letter to Air Canada and Doncar Construction Company, the contractor the city believes was involved.

He said the city will also send those parties the bill for expenses incurred once it tallies the amount of money it spent.
"The water that we had to flush, all the water that we had to supply to our citizens, all the labour...for the people to deliver and give the water," said Rouleau.
He said the bill could be almost $100,000.
Air Canada confirmed it had received the city's letter, but declined further comment. No one at Doncar Construction Company was available to comment.
The city isn't the only entity looking for money from those being blamed for the incident.
Some establishments like Restaurant Da Mangione in Dorval are considering asking Air Canada to reimburse them for lost business.
"People were scared...of coming to eat," said Da Mangione chef Glen Doucet.
Doucet estimates his restaurant lost around $2,000 that weekend.
"They figured that there's no way a restaurant could stay open, you know?"
