Comper has been criticized in the past for his high salary and bonus which, according to some observers, is out of proportion to his value as a president of a fairly standard banking operation. He made $11 million in 2003. His policy of "service shrinkage", or decreasing the number of services offered for the same banking fee, has attracted criticism from customers. In 2006, on his watch, BMO was forced to refund overcharges on mortgage payments of approximately $250 per customer.
