March 21 (Reuters) - Futures tied to Canada's main stock

index fell on Friday, mirroring losses in its Wall Street peers

amid tariff concerns, while investors awaited domestic retail

sales data.

The futures on the S&P/TSX index were down 0.26% at

0642 ET (1042 GMT), while Wall Street's S&P 500 E-minis

fell 0.3%.

Toronto's main stock index ended marginally lower

on Thursday after its biggest rise in over seven months the

previous day, as investors weighed economic uncertainty and

focused on the upcoming snap election.

The Bank of Canada Governor Tiff Macklem said on Thursday

that due to uncertainty about U.S. tariffs, the bank had to

adjust its monetary policy to become less forward-looking than

normal.

The central bank is due to issue its quarterly monetary

policy report on April 16, in which it will predict growth in

the quarters and years ahead.

On Friday, focus will be on retail sales data, scheduled to

be released at 08:30 a.m. ET. January retail sales are expected

to fall 0.4%, as per economists polled by Reuters.

In commodities, oil prices fell, but were on track for a

second consecutive weekly gain due to new U.S. sanctions on Iran

and OPEC+'s latest production plan, which raised expectations of

a tighter supply.

Gold prices fell as the dollar firmed and investors booked

profits after bullion hit three successive all-time peaks this

week.

Copper prices also fell, overshadowed by stronger dollar

following a media report that said China planned to expand its

strategic reserves of key industrial metals.
