About Mainstreet

Mainstreet Credit Union is a member-owned financial cooperative serving communities across Southwestern Ontario, offering a full range of banking, borrowing, and investment solutions.

Our mission is to bring members high-quality personalized advice, supported by technology, in the way that is most convenient for them. Through empowered employees working in a purpose-driven organization, we help our members feel confident about their financial future. Because we are member-owned, our focus stays on people, relationships, and long-term financial well-being.

Advice before products

Financial decisions are personal, so we start by getting to know you.

We take the time to understand your goals, your financial aspirations, and what matters most to you before recommending solutions. From there, we provide personalized advice and flexible options designed to support your plans.

Because our team live and work in the communities we serve, they understand the local market and are empowered to respond quickly and thoughtfully to our members’ needs.

Built for members

Mainstreet Credit Union exists to serve our members, not shareholders. Every person who banks with us is also an owner, and that ownership helps shape how we operate.

Our members elect our Board of Directors and play an important role in guiding the direction of the credit union. That cooperative structure helps keep our focus where it belongs, on supporting the financial success of our members and the communities we serve.

People over profits

As a credit union, Mainstreet is owned by the members we serve. Instead of paying profits to outside shareholders, we reinvest them in better services, competitive rates, and meaningful support for our communities.

Each year, we also reinvest 5% of our income directly back into the communities we serve through local partnerships, initiatives, and programs that make a real difference.

That commitment allows us to strengthen the communities where our members live and work while continuing to invest in better experiences and financial solutions.
