A Canadian large destroyer to complement the River class

What should Canada fit to a 10,000-ton destroyer intended to complement the River class?

Canada should study Japan's next generation of large destroyers because their likely role and systems would complement the Rivers.

A 10,000-ton destroyer is proposed as a companion to Canada's River class. The suggested starting point is Japan's next generation of large destroyers. Canada's industrial position forms part of the reason for looking abroad. The recommendation is to investigate what Japan intends to build, without a specific Canadian weapons or sensor fit proposed.
