When asked about aluminum, he responded, "aluminum, too" will be subject to the trade penalties.
He did not respond to reporters' questions about Trump's tariff announcement as he walked into his hotel following a dinner with French President Emmanuel Macron.
On Sunday night, Industry Minister François-Philippe Champagne said in a social media post that "Canadian steel and aluminum support key industries in the U.S. from defence, shipbuilding and auto.".
"We will continue to stand up for Canada, our workers, and our industries," Champagne said.
A senior Canadian government official told CBC News they've seen the news from Trump and have no additional information at this time.
Some provincial leaders, like Ontario Premier Doug Ford and Quebec Premier François Legault, criticized Trump's tariff announcement for creating economic uncertainty.
Trump imposed steel and aluminum tariffs at 25 and 10 per cent respectively during his first term in March 2018, using national security as justification. »
