OTTAWA -- A computer failure forced an abrupt end to trading on the Toronto Stock Exchange on Wednesday. The shutdown occurred 18 minutes after the exchange opened, and by early afternoon the exchange was still unable to estimate when its system would be restored.
In a statement, the exchange, which is owned by the TMX Group, said that the computer systems that execute trades were not affected. The problem appeared to be with the computers that delivered trading information to brokerage houses and news organizations.
In an interview with BNN, a Canadian business news television channel, Luc Bertrand, the deputy chief executive at TMX, said that the exchange decided to suspend trading after it discovered that only some users were able to track trades.
