Jan 30 (Reuters) - Canada's main stock index rose more than 1% to trade near a record high on Thursday, lifted by mining and technology shares, as investors cheered earnings from some of the big tech megacaps on Wall Street.

The S&P/TSX composite index .GSPTSE was up 1.2% at 25,785.12, its highest level since Dec. 9.

Most sub-sectors were trading higher, with technology .SPTTTK rising 2.9% to an all-time high.

Shares of Celestica CLS.TO jumped 15.6% after the electronics firm surpassed analysts' fourth-quarter profit expectations.

The materials .GSPTTMT sector climbed 2.8%, in tandem with gold prices that rose to a near-record high as potential U.S. tariffs boosted safe-haven demand. GOL/

Industrials .GSPTTIN shares also gained 1.3% to trade at an all-time high.

Investors cheered the earnings reports from some of the so-called "Magnificent Seven" megacap tech stocks that drove the bulk of last year's gains on Wall Street.

"Regardless of what happens tariff-wise and in all this conversation, I think companies are still likely going to do well tracking U.S. markets," said Shiraz Ahmed, senior portfolio manager and founder of Sartorial Wealth at Raymond James.

Wall Street's main indexes also rose on Thursday, driven by post-earnings advances in Meta and Tesla, although Microsoft's weak cloud forecast and downbeat results from Cigna dampened investor enthusiasm. .N

Uncertainty over the Trump administration's policies was also on investors' mind.

Trump has set a Saturday deadline for imposing 25% tariffs on goods from Canada and Mexico, two of the largest U.S. trading partners.

On the data front, U.S. economic growth slowed in the fourth quarter, but robust domestic demand will probably keep the Federal Reserve on a slow interest-rate cut path this year.

Canada's GDP reading for November is scheduled to be released before markets open on Friday.

In single stocks, Rogers Communication RCIb.TO shares fell 1.8% after it added fewer-than-expected wireless subscriptions in the fourth quarter.
