04:21 PM EDT, 08/14/2025 (MT Newswires) -- The Toronto Stock Exchange paused its record run on Thursday, falling for the first time in four sessions, including two record highs, on some profit taking and ahead of tomorrow's release of market-sensitive economic numbers, including factory data, elements of which were inadvertently published today.

The S&P/TSX Composite Index closed down 77.44 points to 27,915.99, even with most sectors up. Healthcare was up near 2.2%. The biggest decliners were Info Tech, down 3.1%, and Industrials, down 1.1%.

Among individual stocks, Air Canada ( ACDVF ) closed unchanged even as Canada's CTV News reported airline management abruptly ended a press conference Thursday after a lineup of members of the Canadian Union of Public Employees, which represents the airlines flight attendants, entered the room and held signs reading "unpaid work won't fly" and "UnfAir Canada," among other statements.

The flight attendants are pressing for an end to unpaid work demanded by the airline and raises to their pay.

Before the news conference ended, CTV News said, Air Canada ( ACDVF ) revealed details on its plans to ground all flights by Saturday if a deal with the union cannot be reached. Some long-haul flights due to depart tonight have already been cancelled. Air Canada ( ACDVF ) plans to cancel 500 trips Friday in a step towards a total stoppage Saturday morning.

The disruption would impact about 130,000 customers per day, including several thousand Canadian travelers who are at risk of being stranded abroad, Air Canada ( ACDVF ) executives said.

On the economics front, at a time when economic data is eagerly awaited ahead of its release, and then dissected afterwards, the lead up to Friday's release of manufacturing and wholesale figures for June, and also existing home sales for July, took an interesting turn today.

Reuters is reported Statistics Canada posted market-sensitive information about June manufacturing data on its website, a day ahead of the scheduled release date.

When Reuters asked why the data was visible, the agency took down the page immediately, indicating an error had occurred. "Statistics Canada takes this incident very seriously. We are conducting a thorough review and will determine whether additional safeguards are required to prevent a recurrence," said agency spokeswoman Maryse Carriere.

Carriere said the agency is proceeding with plans to release the data on August 15 at 8:30 a.m.

The manufacturing data, in particular, is likely to be closely watched Friday for clues on what impact the brewing trade war between Canada and the United States is having on that sector of the economy.

Of commodities, gold traded lower midafternoon on Thursday as the dollar and yields rose following a report that showed U.S. wholesale prices unexpectedly surged in July. Gold for December delivery was last seen down $23.70 to US$3,384.60 per ounce.

But West Texas Intermediate closed higher, rising up from a 10-week low, a day ahead of a summit between the U.S. and Russia and a day after the latest warning the market is becoming over supplied. WTI crude oil for September delivery closed up $1.31 to settle at US$63.96 per barrel, rising off the lowest since June 2. October Brent oil was last seen up $1.08 to US$66.71.
