Late on Monday, Trump said he plans to announce pharmaceutical tariffs over the next two weeks, adding to the levies rhetoric that has unsettled global financial markets and kept investors on edge in recent months.

This follows Trump's tariffs on foreign-made movies, his first on services, that were announced on Sunday.

The governors of six U.S. states said on Monday they have invited Canadian provincial leaders to discuss the impact of the tariffs while being critical of the measures taken by the U.S. president.

Separately, Prime Minister Mark Carney said last week he was expecting "difficult but constructive" talks with Trump on Tuesday.

The focus will be on the Fed's two-day meeting, scheduled to start later in the day, with the central bank widely expected to stay put on interest rates. Investors will closely monitor policymakers' comments for any hints of potential monetary policy easing this year.

In commodities, gold prices rose to a two-week high.

Copper prices edged higher, buoyed by signs of U.S.-China trade talks.

Oil gained more than $1 per barrel on Tuesday.

Canada's main stock index fell on Monday as a drop in oil prices weighed on energy shares and investors reduced some risk ahead of the Fed's interest rate decision this week.
