OTTAWA -- Canadian Prime Minister Justin Trudeau made a call with US President Donald Trump on Wednesday, discussing trade and fentanyl, local media reported.

It's the first time the two have spoken since Trump launched a trade war on Tuesday.

The call lasted 50 minutes about "trade and fentanyl", CBC News reported.

More discussions between the two leaders' teams are expected throughout the afternoon, according to the report.

Trump decided to give a one-month exemption on any autos coming through USMCA, the trilateral trade deal that Trump signed in his first term, known in Canada as CUSMA, the report said.

It wasn't immediately clear what Trump's supposed exemption means for Canadian auto exports to the United States, but it seems like that form of cross-border trade will be able to go on as before, CBC News reported.
