During your account setup you can choose to setup direct deposit for your MSP payments. When you login at app.dr-bill.ca, click the banner that says 'Complete My Payment Information'. Follow the instructions and you'll have the option to complete your direct deposit information electronically.
If you've already setup your account with us and you're not being asked to Complete Your Payment Information on the website, you can fill out this form and send it to firstname.lastname@example.org along with a void cheque. We'll send it on to MSP for you.
