North Warning System Operations and Maintenance Contract

In-Service Support


The mission of the North Warning System (NWS) is to maintain continuous radar surveillance of, and a measure of control over, the northern approaches to North America, contributing to North American defence and Canadian sovereignty. The NWS provides the capability to detect airborne threats within the NWS surveillance area, to provide threat warning and assessment data, as well as provide a command and control capability to the North American Aerospace Defence Command (NORAD) Canadian Air Defence Sector (CADS).


The NWS in Canada is comprised of 11 Long Range Radar (LRR) sites and 36 Short Range Radar (SRR) sites spanning the Canadian Territories and the Labrador Coast. The NWS is divided into 5 zones, each with a Logistic Support Site (LSS). Most of the radar sites are operated remotely. Although DND retains NWS ownership and configuration authority, the contractor possesses responsibility for the care, custody and control of the sites, along with responsibility to deliver the radar data to the operations centre in North Bay.

This contract will be an initial 5 year period with options to renew on a fiscal year basis for up to 5 additional years.
