Jan 21 (Reuters) - Futures for Canada's main stock index fell on Tuesday amid uncertainties over tariffs under U.S. President Donald Trump, while investors awaited domestic inflation numbers.

March futures on the S&P/TSX index SXFcv1 were down 0.1% at 6.44 a.m. ET (1144 GMT).

Trump did not immediately impose tariffs on Canada and Mexico after taking office on Monday, but later said he was thinking of imposing 25% duties starting Feb. 1, citing concerns over illegal immigration and fentanyl smuggling.

Canada sends a majority of its exports south of the border, including energy products.

Investors were also focused on domestic consumer price index $(CPI.UK)$ data, scheduled for release at 8:30 a.m. ET on Tuesday, that could potentially influence the Bank of Canada's interest rate decisions.

Traders bet that there is an 80% probability of a 25 basis-point cut in interest rates this month. 0#BOCWATCH
