A baseline tariff may be the "price" Canada has to pay to continue shipping goods to the US, Canada's finance minister said.

François-Philippe Champagne's remarks came after Donald Trump's State of the Union address, in which the US president said he wants tariffs to eventually replace income taxes to become America's main revenue source.

Champagne's comments follow US trade chief Jamieson Greer saying Canada has to accept "some level of higher tariff" if it wants to do business with the United States.

Trump last week imposed a worldwide 10% tariff through a never-used law known as Section 122 after the US Supreme Court rejected his previous sweeping tariffs policy.

"I think it is pretty well understood now in the world that the view of the American administration is that there'll be a price to access the American market," Champagne told reporters in Ottawa, after being asked if the president's remarks in his speech hinder Canada's hopes of getting tariffs lifted.
