Mainstreet Credit Union was formed in 2013 when Unigasco Community Credit Union in Chatham and Sydenham Community Credit Union in the London Middlesex area joined together. It expanded soon after when Lambton Financial Credit Union in Sarnia and Goderich Community Credit Union joined Mainstreet, broadening its service area across southwestern Ontario.

Mainstreet serves members as a member owned financial cooperative. It offers personal and business banking, borrowing, mortgages, investments, and financial advice, along with agricultural lending and financing for farms and rural businesses.

As a cooperative, Mainstreet reinvests profits into the communities it serves rather than distributing them to outside shareholders. Its work focuses on local ownership, practical advice, and financial services for members, businesses, farms, and communities in southwestern Ontario.
