League Data nears homestretch in first of its kind core-banking transformation of Atlantic Canadian credit union system
League Data, the centralised CIO and technology partner of Atlantic credit unions for over 50 years, has successfully completed 33 conversions to the Mambu cloud native core banking platform. With only four conversions remaining, League Data and its partners are close to completing what is typically a multi-year transformation for one credit union. Remarkably, they will convert the entire Atlantic credit union system, in just over one year.
Prompted by a legacy core banking system approaching end of life in June 2025, League Data saw this as an opportunity to advance the digital transformation of Atlantic credit unions. The recent accomplishment is a major milestone for the completion of the first large-scale core banking transformation of its kind, in the Canadian financial services industry.
"We take pride in what these conversions mean for the credit unions and the members they serve. It’s more than just a technology upgrade. It’s about empowering credit unions with modern, future-positioned solutions to stay competitive, responsive and resilient in an evolving financial landscape."
Chad Griffin
CEO

Strategic partnerships including industry leaders such as AWS, Mambu, MuleSoft and Persistent have been fundamental to providing the expertise and dedicated support necessary for the modernisation journey of Atlantic credit unions. By choosing to partner with Mambu, a global leader in cloud banking, credit unions benefit from a composable, API-driven architecture that increases flexibility, scalability, and enables faster innovation cycles.
"We are proud to work with League Data, an organization that shares our values of delivering best-in-class digital banking solutions to drive community growth and member success. This initiative is a shining example of how forward-thinking leadership and modern technology can come together to deliver meaningful impact at scale.”
Fernando Zandona
CEO
This conversion initiative falls under League Data’s comprehensive program of services to credit unions that brings together products across core banking, digital services, and cybersecurity under a unified change management approach.
Upon completion of the initiative, League Data will explore opportunities to share their partnership experience, cooperative scale and expertise in banking technology with credit unions beyond the Atlantic region. Credit unions can build their future, together with League Data and learn more about Mambu’s next-generation cloud banking capabilities at the Canadian Credit Union Association (CCUA) National Conference - Waves of Change happening from May 11- 14th, 2025 in Halifax, NS.
