Canada-Australia Agreement: Investment in Arctic Over-the-Horizon Radar System

By Published

On 22 June 2026, Canada finalized a $2.5 billion agreement with Australia and BAE Systems Australia to acquire the Arctic Over-the-Horizon Radar (A-OTHR) system. This advanced long-range radar technology, derived from Australia's Jindalee Operational Radar Network (JORN), forms a critical part of Canada's NORAD modernization and Arctic surveillance strategy, aimed at detecting aerial and missile threats over Canada’s Far North. The system is expected to reach initial operational capability by December 2029, with transmission and receiving stations located in southern Ontario. The project includes comprehensive industrial benefits to build Canadian technical expertise and is projected to create approximately 2,270 annual jobs in Canada between 2026 and 2033.

Key Facts

  • Agreement finalized on 22 June 2026.
  • Contract value: $2.5 billion.
  • Partners: Canada, Australia, and BAE Systems Australia.
  • Technology: Arctic Over-the-Horizon Radar (A-OTHR), based on Australian Jindalee Operational Radar Network (JORN).
  • Initial operational capability expected by December 2029.
  • Transmitter located in Kawartha Lakes, southern Ontario; receiver in Clearview Township near Wasaga Beach, Ontario.
  • Project projected to create approx. 2,270 jobs annually in Canada from 2026 to 2033.

Background & Context

Over-the-Horizon Radar (OTHR) technology emits high-frequency radio waves that reflect off the ionosphere, enabling detection of objects beyond the geometric line of sight and Earth's curvature. Canada's A-OTHR program is a key element in the modernization of the North American Aerospace Defense Command (NORAD), a binational organization between Canada and the United States tasked with aerospace warning and defense.

The Australian Jindalee Operational Radar Network is a proven strategic OTHR system used for wide-area air and maritime surveillance. Canada's adoption of JORN technology through this partnership accelerates the development of critical Arctic domain awareness capabilities, enhancing early warning against aircraft and missile threats in Canada's northern territories.

Why This Matters for Exams / Exam Relevance

This agreement highlights significant aspects relevant to defense, international relations, and technology sectors, including the use of OTHR technology for Arctic sovereignty, Canada's strategic partnerships, and NORAD's modernization efforts. Understanding the specifics of this deal—such as the multinational collaboration, technological transfer, timeline, economic impact, and national security implications—is valuable for competitive exams focusing on current affairs, defense studies, and geopolitics.

Points to Remember

  • OTHR technology allows detection beyond line of sight by reflecting signals off the ionosphere.
  • NORAD is a joint Canada-U.S. aerospace defense command.
  • JORN is Australia’s long-range over-the-horizon radar network and the technological basis for Canada's A-OTHR system.
  • The agreement was signed by Canada’s Secretary of State for Defence Procurement Stephen Fuhr and Australia's Deputy Prime Minister and Defence Minister Richard Marles.
  • Initial operational capability is targeted for December 2029, with stations in southern Ontario.
  • The $2.5 billion contract includes industrial benefits to grow Canadian defense industry expertise.
