If your payment is in a blackout period, certain fields — including the Interac email address — cannot be edited.
What Is a Blackout Period?
A blackout period occurs when:
A payment is currently processing
A charge attempt has been initiated
The payment is within the 4-business-day processing window
During this time, key payment details are locked.
Why Are Fields Locked?
To prevent mid-processing delivery failures.
Changing payment details while funds are moving through the banking network can cause:
Failed transfers
Misapplied payments
Rejected transactions
To protect your payment, edits are temporarily restricted.
What Should I Do?
You must wait until:
The payment fully completes
or
The payment exits processing status
Once processing is complete, you can:
Update the Interac e-Transfer email
Edit the payee details
If you need to make urgent changes, wait for the current payment to finish before updating details to avoid disruption.
