The Toronto Stock Exchange reopened Monday after an “unprecedented” hardware failure shut down trading for more than two hours Friday afternoon on Canada’s main stock and derivatives bourses.

TMX Group Ltd., which operates the exchange, said the failure was in a storage device that had been running for more than a year with no problems. The device had a backup in case of failure, but the issue prevented it from engaging. It was not the result of a cyber attack.
