TSX Group has determined the root cause of a service disruption that affected trading on 37 of the more than 2100 issues trading on Toronto Stock Exchange.
The interruption was caused by a trading message protocol issue with one invalid message, and was entirely unrelated to TSX Quantum performance or capacity.
Corrective measures have been implemented.
Shares of BCE Inc. were halted at 2:14 p.m. to address data integrity concerns.
TSX expects trading in shares of BCE Inc. to open as usual tomorrow morning.
