March 3 (Reuters) - Futures for Canada's main stock

index nudged upward, as investors assessed the impact of the

U.S. President's proposed tariffs, and braced for a wave of

upcoming economic data.

By 6:32 a.m. ET (1132 GMT), March futures on the S&P/TSX

index had climbed 0.37%.

The S&P/TSX composite index on Friday ended up

265.21 points, or 1.1%, at 25,393.45, although it was down 0.6%

for February.

As the clock ticked towards the deadline for U.S. President

Donald Trump's tariffs on Canada, Mexico and China, U.S.

Commerce Secretary Howard Lutnick confirmed the tariffs on

Canada and Mexico were slated to take effect on Tuesday.

However, President Trump will decide whether to maintain the

proposed 25% tariff rate, leaving investors anxious.

In Canada, the oilfield drilling and services sector was

already feeling the tremors of the tariff threats, with signs of

deceleration sparking concerns that the much-anticipated

industry recovery might falter if these levies were enacted.

On the economic horizon, investor focus will be on the U.S.

Institute for Supply Management's (ISM) survey, due at 10 a.m.

ET. Services activity data along with at least three employment

reports are also lined up through the week.

The Canadian PMI manufacturing figures for February was to

be released at 09:30 ET, while employment data for the same

period will be unveiled later in the week.

Meanwhile, in commodities, gold prices gained strength after

dipping to a three-week low in the previous session, on a

weakening dollar and a surge in safe-haven buying spurred by

concerns over Trump's tariff strategies.

Oil prices inched higher, buoyed by robust manufacturing

data from China, the world's largest crude importer, which

rekindled hope for increased fuel demand.
