Petrolia, ON – Mainstreet Credit Union is pleased to announce the opening of its new full-service branch in Petrolia, located at 4128 Petrolia Line. The new location officially opens to members on June 23, 2025, bringing a full suite of financial services and enhanced convenience to the growing Petrolia community.
The new branch replaces Mainstreet’s Brigden location, with the entire Brigden team transitioning to the Petrolia branch to continue serving members in a larger, modern space designed to better meet current and future banking needs. The Brigden site will continue to offer cash only ATM services to members.
“This new branch is really about continuing to be there for our members and community as their needs grow and change,” says Chris Inniss, President and CEO of Mainstreet Credit Union. “While the building is new, members will see the same familiar faces and receive the same high quality, personalized advice and support they’ve come to count on.”
The new branch offers a full range of personal, business, agricultural, and investment services, delivered with Mainstreet’s advice-based approach tailored to each member’s unique financial goals. The modern space also offers increased capacity for future growth, educational opportunities, and stronger community connections. Its modern design and central location also help make everyday banking more accessible and convenient for members.
To celebrate the opening, Mainstreet Credit Union will host a Grand Opening Celebration on June 26, 2025, from 9:30 a.m. to 4 p.m. at the new branch. The community is invited to drop in for a ribbon cutting ceremony, refreshments, prize draws, and to meet the branch team.
