We are proud to announce that Information Technology Systems Ontario (ITSO), represented by Allison Ostafew, Executive Director of ITSO, has officially joined the GDX – Global Data Exchange federated network.
As the organization responsible for managing an MLS® System and the professional standards for close to 10,000 users in Ontario, including the members of the Cornerstone Association of REALTORS® and the Brantford Regional Real Estate Association, ITSO plays an important role in supporting real estate professionals through trusted technology and innovation.
This milestone further strengthens GDX’s growing international network and advances our shared vision of standards-based interoperability, cross-border collaboration, and trusted real estate data exchange.
By joining GDX, ITSO and its participating associations gain:
✅ International exposure for public listings

✅ Federated participation while maintaining local governance and control
✅ Opportunities for cross-border collaboration, referrals, and investment
GDX continues to grow as a network built on one core principle:
📌 Local authority. Global opportunity.
Welcome to the network, Allison and the entire ITSO team. We look forward to building meaningful international partnerships together.
