Lucie Brosseau, a spokeswoman for Public Works and Government Services Canada, said the contract with Sikorsky "allows for an excusable delay."
However, she there would be discussions with the company "and fact-finding" about whether the delay is excusable.
Paul Jackson, a spokesman for Sikorsky, confirmed the company was talking with government but couldn't say much more.
"The Cyclone will be the most sophisticated maritime helicopter in the world," he said. "We are working with the government to address issues that have impacted delivery schedules and to allow for delivery as soon as possible."
MHP quite a challenging contract.
