Calian announces ATHORA(TM) to accelerate sovereign defence capability in Canada. Published: May 25, 2026 at 8:40AM EDT OTTAWA, Ontario, May 25, 2026 (GLOBE NEWSWIRE) - Calian Group Ltd. (TSX: CGY), a mission-critical solutions company focused on defence, space, healthcare and other strategic critical infrastructure sectors, today announced the launch of ATHORA(TM), a sovereign system-of-systems interoperability and orchestration platform developed to accelerate military operational readiness and capability integration across evolving C5ISRT environments. Calian will advance ATHORA in collaboration with the Canadian defence industry, including its foundational partner Evertz Microsystems Limited, a globally recognized Canadian technology leader in complex, real-time data fusion solutions. Today's military architecture is characterized by fragmented systems and disconnected data flows and slowing capability integration, operational decision-making, and battlefield readiness. ATHORA will lower barriers to integration with an open system-of-systems (SoS) architecture, designed to connect platforms, communications systems, sensors and mission systems within a common operational environment. Once implemented, the platform will provide secure interoperability, operational coordination and decision advantage across land, sea, air, space, cyber and electromagnetic domains. "Evertz is proud to support ATHORA and collaborate alongside Canadian industry partners to help advance sovereign interoperability, operational readiness and next-generation defence modernization for Canada and its allies," said Romolo Magarelli, President & CEO, Evertz Microsystems Ltd. "With decades of global experience as a real-time operational infrastructure and government solutions partner, the Evertz team will play a central role in Calian's mission to deliver an interoperable Made-in-Canada solution, while developing Canadian-owned IP." Modern military operations depend on the ability to connect communications systems, platforms, sensor data and decision-makers across increasingly complex operational environments. As defence modernization accelerates globally, Canada needs to keep pace with innovation. ATHORA will deliver open, agile and sovereign approaches to interoperability - enabling government, industry, defence primes, OEMs, small to mid-sized enterprises (SMEs) and emerging technology innovators to integrate capability faster and operate together more effectively. "Canada's defence modernization challenge cannot be solved by any one company or capability alone," said Chris Pogue, President, Defence and Space, Calian. "As operational environments become more connected and complex, the Canadian Armed Forces needs to exercise the Right to Integrate (R2I) and evolve capability faster than traditional architectures allow today. ATHORA is being developed to help accelerate that modernization by bringing together government, industry and innovators within a common sovereign interoperability environment - strengthening operational readiness while helping position Canada as a more agile, capable and collaborative defence partner on the global stage." Built to support continuous modernization, ATHORA enables militaries to integrate, adapt, replace and evolve military capabilities independently while maintaining interoperability across the broader operational environment. Rather than replacing existing systems, ATHORA is designed to help defence organizations integrate and operationalize capability faster while preserving sovereign control of systems, data and operational decision making. Supporting Canada's Defence Industrial Strategy ATHORA aligns with the Government of Canada's growing focus on sovereign capability, Canada's Defence Industrial Strategy and broader digital modernization efforts across the CAF initiatives. ATHORA will: Accelerate interoperability across complex defence and C5ISRT environmentsEnable integration across operational and training and simulation environmentsConnect systems and data sources to improve operational awareness and decision-makingSupport interoperability between the CAF, allies and other government departmentsReduce time from experimentation to operational deploymentStrengthen sovereign Canadian capability Canadian-owned intellectual property and domestic operational capacity Canada's defence industrial base is more than 90% SMEs and innovators, yet many organizations continue to face challenges moving capability from development into operational deployment. To help address this gap, Calian recently launched Calian VENTURES, an initiative designed to help Canadian SMEs and dual-use technology companies integrate, validate and operationalize sovereign capability faster within scalable operational environments while retaining ownership of their intellectual property.
