Trading on the Toronto Stock Exchange opened on schedule Thursday after a technical glitch halted trading for most of the previous session.

“I would like to apologize to our customers for the disruption that the halt in trading caused yesterday,” said Tom Kloet, TMX Group CEO, in a release. “I would also like to assure investors that all efforts are being made to ensure that such a disruption in trading does not happen again.”

Shortly after Thursday’s open, the S&P/TSX composite index was down 97.41 points, or 1.12%, at 8,626.70.

The junior S&P/TSX Venture composite index was up 0.37 of a point, or 0.05%, at 723.83.

TMX Group technology team has isolated the issue that resulted in the halt of trading on Toronto Stock Exchange and TSX Venture Exchange, the TMX Group said Wednesday evening.

“Initial findings indicate a network firmware issue resulted in complications with data sequencing, which impacted the delivery of the Level 1 data feeds,” TMX Group said in a release.
