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 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) 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.

The Toronto Stock Exchange's S&P/TSX composite index

reached a five-week high on Monday as markets welcomed

the temporary relief from U.S. trade tariffs.

In commodities, gold prices rose as investors sought

safety amid uncertainties over Trump's trade policies. But

copper prices fell on tariff threats.

Oil prices, also fell as the market reacted

to Trump's plans to boost U.S. oil and gas production.

In corporate news, Canadian company Teck Resources ( TECK )

reported a 50% increase in its annual copper

production for 2024 to 446,000 tonnes.
