TORONTO, Aug 14 (Reuters) - Canada's commodity-linked main

stock index gave back a small part of its weekly gain on Friday

as losses for technology offset gains for energy and metal

mining shares.

The S&P/TSX Composite Index ended down 29.02 points,

or 0.1%, at 36,730.27, after five straight days of gains. It

posted a record closing high on Thursday and a weekly gain of

nearly 1%.

* "The rally in the TSX appears to be commodity driven

rather than a broad-based growth driver," said Robert Gill, a

portfolio manager at Fairbank Investment Management.

* "Gold is showing some leadership. After selling off in

previous months it's really starting to rebound and that's

helped by the U.S. dollar being weaker and the continued

geopolitical uncertainty."

* Transit through the Strait of Hormuz was mostly closed and

U.S. retail sales fell short of expectations, weighing on Wall

Street.

* The TSX's technology sector fell 2.8%, giving

back almost all of the previous day's sharp gain, with shares of

electronic equipment company Celestica ( CLS ) down 4%.

* Air Canada's ( ACDVF ) revenue for September and October is

likely to break records for the two months as more premium

travelers avoid the heat and summer crowds in Europe and Japan,

a senior executive said.

* Still, shares of the airline were down 1.5%, contributing

to a 0.6% decline for industrials.

* The materials group, which includes gold mining

shares, was up 1.2%, tracking gains in precious metals.

* Gold was buoyed by a weaker U.S. dollar after U.S.

inflation readings this week tipped the scales in favor of an

interest rate hold by the Federal Reserve in September.

* The price of oil settled 1.4% higher at $82.40 a

barrel after the U.S. threatened an indefinite naval blockade of

Iran, raising concerns about disruptions to global oil supplies.

* Energy added 0.5%.
