The law requires us to ask for your Social Insurance Number (S.I.N.) when you open an interest bearing account. We may also ask for your S.I.N. to identify you with credit bureaus and other financial institutions for credit matching purposes. Using the S.I.N. is the best way to ensure the credit information actually refers to you, but you may withdraw your consent to this use of your S.I.N. and still obtain loans from us.
