Canada's fourth largest lender by assets,Bank of Montreal, has stopped using outside mortgage brokers and will instead expand its own network of mortgage salespeople. Bank of Montreal (BMO)has been losing market share in the home lending business after it stopped discounting mortgages to compete with rivals last year. The Toronto-based bank made the decision on brokers last month, saying it wasn't as lucrative as selling mortgages through the bank. The bank is also no longer buying third-party mortgages. Bank of Montreal may take a hit in market share from the change. BMO may launch new mortgage products to compete with mortgage brokers, who are increasing market share every year. For more information on mortgages and related products, talk to your mortgage broker. Mortgage brokers have access to a wide range of products.
