Canada is actively looking at potential alternatives to the U.S-built F-35 stealth fighter and will hold conversations with rival aircraft makers, Defence Minister Bill Blair said late Friday, just hours after being reappointed to the post as part of Prime Minister Mark Carney’s new cabinet.

The remarks came one day after Portugal signalled it was planning to ditch its acquisition of the high-tech warplane.

The re-examination in this country is taking place amid the bruising political fight with the Trump administration over tariffs and threats from the American president to annex Canada by economic force.

There has been a groundswell of support among Canadians to kill the $19-billion purchase and find aircraft other than those manufactured and maintained in the United States.

After years of delay, the Liberal government signed a contract with the U.S. defence giant Lockheed Martin in June 2023 to purchase 88 F-35 jets.

The conversation about Canada getting out of the deal is currently taking place with the military, Blair told CBC’s Power & Politics.

“It was the fighter jet identified by our air force as the platform that they required, but we are also examining other alternatives — whether we need all of those fighter jets to be F-35,” Blair said.

Canada has already put down its money for the first 16 warplanes, which are due to be delivered early next year. 

Blair is suggesting that the first F-35s might be accepted and the remainder of the fleet would be made up of aircraft from European suppliers, such as the Swedish-built Saab Gripen, which finished second in the competition.

“The prime minister has asked me to go and examine those things and have discussions with other sources, particularly where there may be opportunities to assemble those fighter jets in Canada,” Blair said.

That was an indirect reference to the Swedish proposal, which promised that assembly would take place in Canada and there would be a transfer of intellectual property, which would allow the aircraft to be maintained in this country.

Major maintenance, overhaul and software upgrades on the F-35 happen in the United States.

The notion of Canada flying a mixed fleet of fighter jets is something the air force has long resisted, even though it did so up until the 1980s when the current CF-18s were purchased. It would mean two different training regimes, separate hangars and infrastructure and a different supply chain — all of which defence planners have insisted for decades is too expensive.

Prior to Blair’s statement, Lockheed Martin was asked about Portugal’s planned exit from the program and whether it would have an impact on Canada.

“Lockheed Martin values our strong partnership and history with the Royal Canadian Air Force and looks forward to continuing that partnership into the future,” said Rebecca Miller, Lockheed Martin’s director of global media relations, in a statement.

“Foreign military sales are government-to-government transactions, so anything further will be best addressed by the U.S. or respective customer governments.”

Miller also addressed online misinformation that suggested the F-35s have a so-called “kill switch” that could turn off aircraft belonging to allies — or hobble their capabilities, should the U.S. government order it to do so. 

“As part of our government contracts, we deliver all system infrastructure and data required for all F-35 customers to sustain the aircraft,” Miller said. “We remain committed to providing affordable and reliable sustainment services to our customers that enable them to complete their missions and come home safely.”

There would be some form of contract penalty should Canada not proceed with the entire purchase. How much it would cost to get out of the contract remains unclear.
