So got some mail from Paradise saying they have an online banking option involving the Interac payments. They didn't mention withdrawals so I'm assuming one can't withdraw via this option. I find it amusing how enthusiastic the mail was about how we should worry no more about depositing because they've solved that problem -- if you somehow don't lose money though they aren't working on any solutions to make withdrawing any easier. Maybe one can withdraw but since they didn't mention it I'm not so confident -- I've fired off the question to support.
As far as I can tell RBC charges $1.50 for Interacs (no charge to receive) and PCFinancial is free. Don't know about other banks but I'm sure the info is on their sites.
