Prime Minister Mark Carney has asked for a review of Canada’s plan to purchase a fleet of F-35 fighter jets.

The deal with Lockheed Martin and the U.S. government is for 88 planes at a cost of about US$85 million each.

A spokesperson for Defence Minister Bill Blair said Carney has asked Blair to look into whether the F-35 contract is the best investment for Canada, or if there are better options.

“We need to do our homework given the changing environment, and make sure that the contract in its current form is in the best interests of Canadians and the Canadian Armed Forces,” Blair’s press secretary Laurent de Casanove said.
