Their complaint is that the Canadian government subsidized development costs (which it arguably did), so it's unfair competition. https://en.wikipedia.org/wiki/Countervailing_duties However Boeing is also quite subsidized, just more indirectly through defense contracts. And what's more, Boeing doesn't even offer a competitive product. They don't sell any aircraft in this size range. |
Boeing is the largest winner of state and local tax incentives valued in $13 billion. Most of these go to commercial aircraft manufacturing. DoD also awards defense contracts that intend to keep strategic commercial technologies within US (just like all large nations).
Boeing and Airbus have been involved in legal battle over subsidies over a decade. When WTO found that there was only $1 billion in illegal subsidies in 777X development and rest $8 billion were legal subsidies, Boeing was celebrating.
