Banking that is invested in you

As a cooperative we exist solely for you. Without commissions, or the need to make shareholders rich, we can focus solely on what products and services are best for you, nothing else.

We are local

We understand Southwestern Ontario. Decisions are made here. Profits go back to our communities.

We share

When's the last time your bank paid you? Never? We do through our profit-sharing program.

The mortgage experience can be tough as a young couple, Mainstreet was good at making things effortless for us, plus we found a financial advisor who really worked with us on our future plans and helped us move from our starter condo to our dream home.
