How an Interac e-Transfer actually moves money

You send an e-Transfer to someone's email or phone number; Interac uses that alias to route a notification, not the cash itself. The recipient either gets autodeposit or answers a security question to claim it. Behind the scenes, your bank and their bank exchange records and settle the real money through Payments Canada's clearing and settlement system. It feels instant to the people involved, but the interbank settlement that makes the money final runs separately underneath that experience.

The flow at a glance

money (funds move) message (instructions) exception

Who’s involved

Sender: Person initiating the transfer from their bank's app or site
Sender's bank: Debits the sender and instructs Interac; participant in settlement
Interac: Operates the alias/notification routing and the e-Transfer platform (message layer)
Recipient: Person who receives the notification and claims or autodeposits the funds
Recipient's bank: Credits the recipient; participant in settlement
Payments Canada: Operates the underlying clearing and settlement system that finalizes interbank money movement

How it moves, step by step

1
messageSender
The sender opens their bank app, enters an amount and the recipient's email or phone number (the alias), and optionally sets a security question.
2
moneySender's bank
The sender's bank typically places a hold on or debits the funds from the sender's account so the amount is reserved.
3
messageInterac
Interac looks up the alias in its directory and sends a notification to the recipient, it is routing a message, not carrying the cash.
4
messageRecipient
If the recipient has autodeposit registered, the funds are directed straight to their account; otherwise they click the link and answer the security question to claim it.
5
messageRecipient's bank
The recipient's bank receives the claim instruction and prepares to credit the recipient's account.
6
moneyRecipient's bank
The recipient's bank credits the recipient's account, often making funds available right away even before the interbank settlement is final.
7
moneyPayments Canada
The two banks settle the underlying obligation through Payments Canada's clearing and settlement system; this interbank money movement is when funds become final between the banks.
8
exceptionSender
If the recipient never claims the transfer (no autodeposit and no answer), it expires and the held funds are typically returned to the sender.

When it’s final

The experience feels instant and funds are often usable immediately, but the interbank settlement that makes the money final runs separately through Payments Canada's underlying clearing and settlement system, on that system's own cycle rather than at the moment the recipient sees the funds. Exact timing depends on the participating banks and the underlying system.

Common misconceptions

Myth: The money is attached to the email and travels through Interac to the recipient.
Reality: The email or phone number is just an address Interac uses to route a notification. The actual money moves as a debit and credit between the two banks and is settled through Payments Canada, Interac handles the message layer, banks move the funds.
Myth: Because it lands instantly, the transfer is fully settled and irreversible the moment the recipient sees it.
Reality: Showing available funds quickly is the recipient's bank crediting the account; the interbank settlement that makes the money final happens separately through the underlying system. Availability to the recipient and finality between the banks are not the same step.
