Significant technical issues have led Interac to temporarily take their E-Transfer service offline.
In a statement, Interac says it is an internal technical issue resulting in transaction delays, and the suspension of a number of transfers.
They are reassuring the public by saying the system and data remains secure.
While the system is offline, banks will not be able to process any transactions.
Interac says any transfers currently in transit will be processed once the system is restored.
