ATCO FRONTEC AND INUVIALUIT DEVELOPMENT CORPORATION PARTNERSHIP SECURES RADAR DEFENCE CONTRACT FOR CANADA'S NORTH

The government of Canada has awarded a joint venture between Atco Ltd.'s Atco Frontec Ltd. and Inuvialuit Development Corp. (IDC) a two-year contract valued at $48.4-million to design, build, install and operate a new radar defence system in the Northwest Territories. Under the terms of the joint venture agreement, IDC holds 51-per-cent ownership, while Atco holds 49 per cent. The Polar over-the-horizon radar (POTHR) system will use technology that can detect targets at long ranges, typically hundreds to thousands of kilometres, beyond the typical radar horizon.

"We've assembled an incredible team of experts to deliver a highly technical, made-in-Canada solution for the POTHR program," said Jim Landon, president, Atco Frontec. "Our partnership has decades of experience operating and maintaining defence infrastructure in the Northwest Territories and across Northern Canada."

The enhanced infrastructure is part of a government of Canada funding plan to strengthen the country's continental defence capabilities, including to modernize the North American Aerospace Defence Command (NORAD).

"We are proud to leverage our deep knowledge of the region and work alongside Inuvialuit businesses to drive this project forward," said Robert C. McLeod, chair, Inuvialuit Development. "This collaboration will create lasting economic opportunities, strengthen local capacity and deliver direct benefits to Inuvialuit beneficiaries for years to come."

The joint venture has teamed up with Canadian-owned D-TA Systems Inc., a global technology leader with a proven record and expertise delivering over-the-horizon radar systems. D-TA has already provided two over-the-horizon radar systems to Canada, the largest in the world, on time and on budget.

"In joining forces with Atco Frontec and IDC, we are leveraging the unmatched logistics and indigenous partnership capabilities of two Canadian companies, while addressing the stringent logistic and construction challenges of delivering, installing and operating this critical radar technology in the harsh environment of Canada's north," said Dr. Dipak Roy, founder and executive chairman, D-TA Systems.

The partners are working with a number of Canadian-owned and Canadian-operated suppliers and contractors. The contract commenced on March 28, 2025, with a term of two years and potential for three additional one-year options.
