I thank the member for his question.
Of course, the needs remain. NORAD has indicated the need for domain awareness, not only on the air defence side, but also on the maritime defence side. As you mentioned, funding was provided by the Canadian government last year to maintain the current system, which is the North Warning System, until it is replaced by a system with increased capabilities.
The Defence Research and Development Canada, or DRDC, team has been working with U.S. researchers to advance the technology associated with the over-the-horizon radar for the acquisition of such a system. It is one of a series of acquisitions at various levels to address threats that may arise in maritime or airspace. This is the main system, but there are several others that involve space surveillance systems.
