(Adds Interac statement, customers' tweets)
TORONTO, June 30 (Reuters) - Interac, which operates an email money transfer service used by several Canadian banks, said on Friday it was experiencing technical difficulties preventing some bank customers making payments ahead of an extended holiday weekend.
"We are experiencing a significant technical difficulty impacting the Interac e-Transfer service resulting in service delays and disruptions. We are working to resolve the situation as quickly as possible," Interac said in a statement.
Bank of Montreal BMO.TO and Canadian Imperial Bank of Commerce CM.TO tweeted that they were experiencing difficulties, while Royal Bank of Canada RY.TO and Bank of Nova Scotia BNS.TO customers reported problems making payments.
Some people took to Twitter to complain they were having trouble making rent payments and other critical transfers.
"Rent money in limbo. Not even showing in e-transfer history and can't even cancel it," said one tweet by Richard K, a BMO customer.
"Please fix Scotiabank e-transfer soon. I have a family emergency, money transfer is vitally important right now," tweeted a Scotiabank customer with the handle Kathtastic.
RBC and Scotiabank did not immediately respond to requests for comment.
