OTTAWA - Canadian Prime Minister Mark Carney has asked for a review of Canada's plan to purchase a fleet of F-35 fighter jets from the United States, local media reported Saturday.

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

According to the CTV News report, a spokesperson for Defense 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," the spokesperson was quoted as saying.
