OTTAWA (Reuters) -Canada will wait until next week to respond to the latest U.S. threat of tariffs and nothing is off the table regarding possible countermeasures, Prime Minister Mark Carney said on Thursday.

Carney told a press conference that he would speak to provincial premiers and business leaders on Friday to discuss a coordinated response to the auto sector tariffs that U.S. President Donald Trump announced on Wednesday.

"It doesn't make sense when there's a series of U.S. initiatives that are going to come in relatively rapid succession, to respond to each of them. We're going to know a lot more in a week, and we will respond then," he said.

One option for Canada is to impose excise duties on exports of oil, potash and other commodities.

"Nothing is off the table to defend our workers and our country," said Carney, who added that the old economic and security relationship between Canada and the United States was over.

Carney broke off from campaigning ahead of an April 28 general election to make the announcement.

He is calling on voters to give his Liberal Party a strong mandate to deal with Trump.
