TORONTO — Canada's defense minister repeated a threat Wednesday to cancel the purchase of 18 fighter jets from Boeing because of the company's trade complaint against Canadian plane-maker Bombardier.



Harjit Sajjan said Boeing's action against Bombardier is "unfounded" and not the behavior of a "trusted partner." He said buying the Super Hornet fighter jets "requires a trusted industry partner."



Sajjan urged Boeing to withdraw the complaint in a speech. Canada's foreign minister has also threatened to block the order.



"Our government — and I stress this —T our government is disappointed in the action of one of our leading industry partners," he said.





Chicago-based Boeing's trade complaint prompted a U.S. Commerce Department anti-dumping investigation that could result in duties being imposed on Bombardier's new larger C Series passenger aircraft. Boeing insists the plane receives Canadian government subsidies that give it an advantage internationally.

Canada's threat comes amid increasing trade disputes with the U.S.

Scott Day, a spokesman for Boeing, noted that Sajjan also recognized Boeing as a strong partner in the past and for the future. Day defended the company's trade action.

"This is a commercial matter that Boeing is seeking to address through the normal course for resolving such issues," Day said in an email.

Boeing petitioned the U.S. Commerce Department and the U.S. International Trade Commission to investigate subsidies of Montreal-based Bombardier's C Series aircraft. Boeing says Bombardier has received more than $3 billion in government subsidies that let it engage in "predatory pricing."

Brazil has also launched a formal complaint to the World Trade Organization over Canadian subsidies to Bombardier. Sao Paolo-based Embraer is a fierce rival of Bombardier's.

The Quebec government invested $1 billion in exchange for a 49.5 percent stake in the C Series last year. Canada's federal government also recently provided a $275 million loan to Bombardier, which struggled to win orders for its new medium-size plane. But Bombardier won a 75-plane order for the C Series from U.S.-based Delta Air Lines in 2016. Bombardier said its planes never competed with Boeing in the sale to Delta.
