A Non-Sufficient Funds (NSF) fee occurs when your chequing account does not have a sufficient balance to cover a transaction. For example, if Mogo tries to withdraw your monthly payment from your bank account, but is unable to because there is not enough money in your bank account. You will be charged an NSF fee by your bank and by Mogo. With Mogo, the NSF fee can be up to $50, depending on your province.
