CORRECTED-CERAWEEK-Canada could boost oil supplies to US, but also needs new markets, Alberta premier says

March 10 (Reuters) - Alberta Premier Danielle Smith said on Monday that the Canadian province would continue to supply crude oil to the United States but that U.S. President Donald Trump's tariff threats also underscored the need for new markets.

She said U.S. tariffs currently do not apply to Canadian crude oil, but that producers were being required to fill out paperwork to prove their supplies are in compliance.

"I think that we should have a zero tariff on this critical resource," she said at the CERAWeek energy conference in Houston.
