If you cancel an Interac e-Transfer that you sent, kindly note that the option available to "Cancel" an Interac e-Transfer sent from Venn, is not a guaranteed option as it depends on if the recipient has or does not have auto-deposit registered on their email.
You may be able to cancel the transfer if:
It was sent to the wrong email address and the transfer remains unclaimed, OR
The recipient hasn’t set up auto-deposit and hasn’t accepted the funds.
Important: Cancellation is done on a best-efforts basis and depends on the recipient’s bank cooperating to return the funds. If the status still shows “In Progress” or "Completed" 24 hours after you initiate the cancellation, it likely means the cancellation failed and the funds were received by the recipient.
