(Updates to close)

By Nivedita Balu

July 7 (Reuters) - Canada's main stock index closed

lower on Monday, tracking U.S. markets after U.S. President

Donald Trump announced fresh tariffs against Japan and South

Korea, sparking trade jitters among Canadian investors.

The benchmark S&P/TSX composite index closed down

15.88 points, or 0.06%, at 27,020.28.

The TSX turned lower earlier in the day while investors

awaited updates on trade developments. The index had posted

fresh all-time highs every day last week and touched another

record high on Monday before turning red.

Wall Street's major indexes closed lower after Trump's

tariff announcements.

"It's more just a warning that these are friendly

countries that are getting to the tariffs, and that's probably a

reminder that Canada is not out of the woods yet," said Greg

Taylor, chief investment officer at PenderFund Capital

Management.

"We're starting to see that the tariff (worries) haven't

gone away yet fully, that there's still going to be uncertainty

around earnings. Investors are saying, 'Well, we've had such big

gains. Why don't we hit pause and take some profits?'"

Healthcare stocks fell 0.3% and energy

stocks were down 0.6%.

Mining stocks gained 1.2% as gold pared losses

after Trump's tariff news, prompting some safe-haven interest.

Among individual stocks, ATS Corporation ( ATS ) was the

biggest loser on the TSX, falling 8%, as CEO Andrew Hider is set

to leave the company.

Sandstorm Gold ( SAND ) gained 6.2% after Royal Gold ( RGLD )

said it will acquire the company for about $3.5

billion.

Horizon Copper ( HNCUF ) gained 67.7% after Royal Gold ( RGLD )

announced the acquisition of the company in an all-cash deal

worth $196 million.
