The Canadian payment processing firm told Global News in a statement that the outage affecting the ability to process transactions lasted approximately 90 minutes.
Reports of the outage first appeared on the Downdetector.ca website before noon eastern time on Saturday.
Moneris posted a message on X, the social media site formerly known as Twitter, at around 2 p.m. saying it had resolved the network problem.
The firm says merchants may experience some transaction slowness while systems catch-up.
“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,” Moneris’ statement said.
It is unclear how many businesses and transactions were affected.
