April 23 (Reuters) - Canada's main stock index edged

lower on Thursday, led by declines for technology and metal

mining shares, as investors weighed evidence that the war in the

Middle East is hurting the global economy.

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

ended down 42.18 points, or 0.1%, at 33,912.93.

There are signs that the war is beginning to weigh on the

global economy and specific industries, Colin Cieszynski, chief

market strategist at SIA Wealth Management, said in a note.

"Higher energy prices are now filtering into corporate

outlooks and forward expectations," Cieszynski said.

The global economy is facing ever more tangible strains from

the energy shock triggered by the Iran war as factories grapple

with soaring production costs and activity weakens even in

services sectors, major surveys showed.

Canadian producer prices rose 2.4% in March from February on

higher prices for energy and petroleum products, as well as

chemical products, linked to the closure of the Strait of

Hormuz.

The price of oil settled 3.1% higher at $95.89 a barrel

after reports that air defenses were engaging targets over

Tehran and of a power struggle between Iranian hardliners and

moderates.

Technology fell 4.5%, with shares of Shopify ( SHOP )

and Constellation Software ( CNSWF ) both down 5.7%, as

U.S. corporate results revived concerns that the software

sector's traditional business models could be upended by new AI

tools.

The materials group, which includes metal mining

shares, ended 1.5% lower as gold and copper prices

fell.

Teck Resources ( TECK ) beat analysts' estimates for

first-quarter profit, aided by an increase in copper prices and

record sales, while the company's proposed merger with Anglo

American remained on track. The miner's shares rose

2.8%.

Industrials also added 2.8% as railroad stocks

notched gains and after solid waste operator Waste Connections ( WCN )

beat first-quarter revenue estimates, sending its

shares 8.3% higher.

Energy was up 1.8%.
