The Toronto-based technology company issued a statement saying there was nothing to suggest the outage was related to a cyber attack.
Complaints about outages started rolling in to the Downdetector.ca website before noon eastern time, but Moneris did not say when the outage started.
About three hours later, Moneris posted a message on X — the social media site formerly known as Twitter — saying it had resolved the network problem.
It remains unclear how many businesses and transactions were affected, but data provided by Downdetector.ca indicated complaints had come in from across the country.
In a statement provided to The Canadian Press, the company said the outage lasted about 90 minutes.
"We have resolved the network outage and returned transaction processing to normal," the statement said. "We continue to investigate the root cause of the issue. There are no indications this appears to be cyber-attack related and all transaction systems are functioning normally again."
The company, a joint venture between Royal Bank and BMO Bank of Montreal, said transaction processing could be slow as its systems catch up with the backlog.
Moneris says it supports more than 325,000 merchant locations across Canada.
This report by The Canadian Press was first published Sept. 23, 2024.
