Rather than selling one lender's products, a mortgage broker takes a single application and compares rates across banks, credit unions, and alternative lenders to find the best fit. Sarnia sits at the southern tip of Lake Huron on the St. Clair River, across from Port Huron, Michigan, and its economy is anchored by the petrochemical and refining plants of Chemical Valley. The region has a variety of property types, including cottages and waterfront homes along the Lake Huron shoreline. These are the kinds of files that lenders can treat very differently, which is where a broker's wider lender panel helps. Below are some notable brokerages serving Sarnia borrowers, from online brokerages to firms with a Sarnia office.

About Mortgage Brokers in Ontario

Agents begin at Level 1 and can progress to Level 2, and then a full mortgage broker licence through additional education, and every licensed brokerage is required to hold errors and omissions insurance.
