OTTAWA, Feb 3 (Reuters) – Canada will do all it can ​to support jet maker Bombardier, ‌Industry Minister Melanie Joly said on Tuesday, ‌speaking after U.S. President Donald Trump threatened certification of the firm’s planes.

Trump’s threats initially raised alarm among ⁠airlines, customers ‌and aviation analysts and questions remain over whether he ‍would follow through with a threat to slap 50% tariffs on jets made ​north of the border. Shares ‌of Bombardier closed up 1.8% on Monday after slumping on Friday.

“It (Bombardier) is a crown jewel for Quebec and Canada and is very, very ⁠important for us. ​And we will ​do all we can, of course, to support the company ‍and the ⁠aeronautical sector,” Joly told reporters.

Joly, who also said she had ⁠spoken to Bombardier CEO Eric Martel on ‌Monday, did not give details.
