June 3 (Reuters) - Canada's main stock index pulled back

on Wednesday from a record high as tensions in the Middle East

rose, with technology and metal-mining shares leading the

declines.

The Toronto Stock Exchange's S&P/TSX Composite Index

ended down 367.92 points, or 1.1%, at 34,801.54, after

notching a record closing high on Tuesday.

* Wall Street stocks also pulled back from record highs

as the U.S. and Iran traded a new round of air strikes, the

latest test of a shaky ceasefire.

* "It's a tail risk and markets are pricing it as a tail

risk," said Josh Sheluk, portfolio manager at Verecan Capital

Management. "If markets thought escalation was the highest

probability outcome, then they'd probably be a lot lower right

now."

* Investors worry that elevated oil prices due to the

conflict will raise inflation pressures globally. The price of

oil settled 2.4% higher at $96.02 a barrel.

* Adding to global economic headwinds, the Trump

administration has proposed new tariffs of up to 12.5% on

imports from 60 economies after determining they had failed to

curb trade in goods made with forced labor, an assertion that

was rejected by U.S. trading partners.

* Technology shares fell 3.5%, with shares of

Constellation Software Inc ( CNSWF ) down 4.7%.

* Shopify Inc ( SHOP ) said on Tuesday its board had

approved an additional $3 billion share buyback program. Shares

of the e-commerce company ended 3% lower.

* The materials group, which includes

metal-mining shares, was down 3.2% as gold and copper

prices fell.

* Heavily weighted financials lost 0.6% and

industrials ended 0.7% lower.

* Four of the 10 major sectors ended higher, including

energy and consumer staples, which added

1.2% and 1.5% respectively.
