CANADA STOCKS-TSX futures flat as market optimism fades

April 24 (Reuters) - Futures for Canada's main stock index were subdued on Thursday, as investors assessed the impact of the U.S. administration's shifting positions on tariffs.

June futures on the S&P/TSX index SXFcv1 were down 0.01% at 6.45 a.m. ET (1045 GMT).

The Toronto Stock Exchange's S&P/TSX composite index .GSPTSE had climbed to a three-week high on Wednesday, posting its second straight session of gains, after signals that the White House was willing to ease trade tensions with China and U.S. President Donald Trump has softened his stance toward Federal Reserve Chairman Jerome Powell.

But later that day, Trump said a 25% tariff imposed on cars imported from Canada to the United States could go up.

The spotlight on Thursday will be on precious metal mining companies as gold was heading back towards Tuesday's record high.

Copper prices were hovering below a three-week high, bolstered by a weaker dollar but unsettled by continued uncertainty over tariffs.

Oil prices recovered some losses after falling nearly 2% in the previous session.

Investors' attention was also divided among a series of earnings reports from U.S. companies, which presented a mixed picture.

Canadian retail sales data, due on Friday, is expected to offer insights into consumer spending patterns amid the uncertainty around U.S. tariffs.

Company-wise, miner Teck Resources TECKb.TO beat first-quarter expectations, helped by higher commodity prices and copper sales volumes.
