I need to cancel a transfer, but the recipient has already accepted the deposit. How do I reverse an Interac e-Transfer transaction?

Unfortunately, once a deposit has been made there is no way to reverse the transaction. You’ll have to make arrangements directly with the recipient. You should only send money transfers to parties you know and trust. For most Interac e-Transfer uses (sending money to family and friends, repaying IOUs, sending money as gifts, etc.), you will know the recipient well. For uses where you may not know the recipient (e.g., online auction purchases), take the same precautions you would take when making cash purchases. For online auctions and purchases, be sure to read and follow any steps recommended by the operators of these websites to safely transact.
