Interac Online is an immediate, secure, and easy-to-use online Deposit method. All you need is access to online banking through a Participating Financial Institution. Check to see if your Financial Institution is compatible with Interact Online here.
It is not possible to withdraw to INTERAC ONLINE, getting your winnings returned would have to be via the Bank Transfer (Bank Transfers are subject to certain restrictions by some Canadian Banks. Read more on withdrawals to Bank here).
