Good to know: 

• A fee of $16 to $30 may apply. Make sure you have at least this amount in your account, otherwise we won’t be able to complete your request.
• Stopping a pre-authorized debit does not end your contract with your supplier. Contact them if you need to cancel your agreement.
• If you stop a pre-authorized debit that is dated today, the payment may be debited from your account, but will be refunded the next business day after we process your request.
• You can’t stop a withdrawal from National Bank or its subsidiaries. Call us at 1-888-835-6281 to discuss your options.
