TORONTO, June 23 (Reuters) - Canada's main stock index edged

down on Tuesday as lower commodity prices and a tech-led selloff

on Wall Street weighed on the market, with metal mining shares

leading the declines.

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

ended down 74.8 points, or 0.2%, at 34,927.38, after

clawing back much of its earlier declines.

* The Nasdaq and the S&P 500 posted steeper declines,

dragged down by sharp losses in semiconductor stocks as

investors scrutinized growing debt-funded AI spending and braced

for a more hawkish U.S. Federal Reserve.

* "You've got a broader tech selloff filtering into Canada,

plus a selloff in commodity prices," said Michael Dehal, senior

portfolio manager at Dehal Investment Partners at Raymond James.

* "The TSX is largely commodities-driven (so) we're getting

hit from both ends of the spectrum," Dehal said.

* The price of gold fell 1.9% as the U.S. dollar

climbed to a 13-month high against a basket of major

currencies on increased expectations of a Fed interest rate

hike.

* Copper was down 3.4%, while oil settled 0.9%

lower at $73.21 a barrel as investors kept a close watch on

crude flows through the Strait of Hormuz following signs of

progress in U.S.-Iran peace talks.

* The materials group tumbled 4.4%, while

technology ended 0.4% lower.

* Shopify Inc ( SHOP ) will ban all vapes from its platform

as soon as this week after pressure from a group of U.S. state

attorneys general. Shares of the e-commerce company ended 0.2%

higher.

* Seven of 10 major sectors notched gains, including

consumer staples, which jumped 4.1%.

* Alimentation Couche-Tard Inc ( ANCTF ) shares were up 11.7%

after the convenience store operator's quarterly results beat

estimates.
