Oct 28 (Reuters) - Canada's main stock index climbed on

Tuesday, propelled by a robust technology sector rally after

Celestica ( CLS ) shares soared to record heights, while investors

awaited pivotal central bank decisions.

At 10:15 a.m. ET (1415 GMT), Toronto's S&P/TSX composite

index was 0.5% at 30,431.06 points.

Celestica ( CLS ) jumped 9% to record levels after the data

center infrastructure provider raised its 2025 revenue forecast

and reported third-quarter revenue and profit above analyst

expectations.

The gains in Celestica ( CLS ) led information technology sector

to rise 2.3%.

Financials and utilities were also

a bright spot, advancing 0.3% and 0.4%, respectively.

Despite these gains, broader market sentiment remained

subdued.

Energy shares led the retreat with a 0.9% decline

as oil prices tumbled nearly 2%. Investors continue weighing the

implications of U.S. sanctions on Russia's two largest oil

companies against potential OPEC+ production increases.

The materials sector also dropped 0.4% as gold

prices fell more than 2%. Improving global trade sentiment

diminished safe-haven demand for precious metals.

"Tensions are easing a little bit in the trade talks

globally, Japan and the U.S. have settled on a rare earth supply

deal, and that is not the case for Canada," said Michael Sprung,

president at Sprung Investment Management.

Global investors are optimistic that U.S. President

Donald Trump will strike a long-awaited trade deal with China

during his Asia tour. Trump has signed a deal with Japan to mine

and process critical minerals and rare earths.

For Canada, however, trade relations deteriorated last

week when Trump announced an additional 10% tariff on Canadian

imports, citing what he called a misleading tariff-related

advertisement.

Investors will also focus on central bank policy decisions

scheduled on Wednesday, with both the Bank of Canada and the

U.S. Federal Reserve widely expected to implement a

quarter-point interest rate cut.

In other notable movers, Cameco Corp ( CCJ ) shares jumped

20.2% after the announcement that the uranium supplier

Westinghouse Electric and Brookfield Asset Management ( BAM )

will build at least $80 billion of new nuclear reactors across

the United States in a partnership with the U.S. government.

Brookfield shares climbed 2.5%.
