Oct 30 (Reuters) - Canada's commodity-linked main stock

index ended lower on Wednesday as investors took profit in

high-flying metal mining shares and weighed the potential for a

weaker Canadian dollar to revive inflation.

The S&P/TSX composite index ended down 54.76

points, or 0.2%, at 24,507.79, its seventh decline in eight

trading days since notching a record closing high.

"Canada is following global sentiment which is a little bit

weaker," said Ben Jang, a portfolio manager at Nicola Wealth.

"It's investors taking profits where they can."

Bank of Canada Governor Tiff Macklem and Senior Deputy

Governor Carolyn Rogers were due to appear before the Standing

Senate Committee on Banking, Commerce and the Economy after the

closing bell.

The central bank has eased interest rates by one and a

quarter percentage points since June to support the economy.

"We need to cut rates but if we cut rates too aggressively,

we'll weaken the (Canadian) dollar too much ... the weaker

dollar effectively importing inflation," Jang said.

The Canadian currency has weakened 3.5% since late September

to 1.39 per U.S. dollar or 71.94 U.S. cents. Earlier on

Wednesday it touched a 12-week low at 1.3940.

The materials sector, which includes fertilizer companies

and metal mining shares, fell 1% even as the price of gold

extended its record-setting run. The sector has advanced 34%

since the start of the year.

Technology was also a drag, falling 0.8%. Industrials ended

0.4% lower.

Not all sectors lost ground. Consumer staples rose 1.3%,

while energy added 0.3% as the price of oil settled 2.1%

higher at $68.61 a barrel.

Shares of Secure Energy Services Inc ( SECYF ) jumped 9.9%

after the company reported third-quarter results.
