Do you mean Bombardier? The aviation company with $16B in revenue and 65k employees? Looks like there was a tariff imposed on one of their models due to a complaint by Boeing but was overturned 4 months later in Jan 2018.

If this is the company you're talking about, can you describe what you mean by "literally was ended"?

Without the Airbus deal for the C-Series Bombardier was basically in bankruptcy exactly because of those tariffs. It felt like quite a targeted attempt to, as you put it, suppress competitors.

Maybe so, but that’s quite different from “literally ended.”
