Canada’s main stock index gained ground in trading, led by the industrial sector which pushed higher on news of a takeover deal for Aecon Group Inc.

Shares of the construction company advanced $3.21, or 19.43%, to $19.73 at the close of markets after it announced that it signed a deal Thursday to be acquired by CCCC International Holding Ltd. of China.

Aecon CEO John Beck said the $1.5 billion acquisition deal will help it bid for larger and more complex projects, subject to shareholder and government approvals.

The Toronto Stock Exchange’s S&P/TSX composite index was up 36.86 points to 15,891.63.

Meanwhile, Potash Corp. of Saskatchewan was down 29¢, or 1.15%, to $24.85 after it said it earned a third-quarter profit of $53 million, down from $81 million a year ago, as it works to close its merger with Agrium Inc.

Other major companies reporting earnings included Teck Resources Ltd. Restaurant Brands International Inc. and Husky Energy Inc., which all saw their stock prices fall.

“It’s all earnings, earnings, earnings … on the TSX,” said Kathryn Del Greco, an investment adviser with TD Wealth.

“The Aecon deal is very exciting,” Del Greco said. “And with Suncor, it’s nice to see some positive numbers coming out the oil patch.”
