In Budget 2022, the Government of Canada announced the Department of National Defence will publish a review of its current defence policy, Strong, Secure, Engaged. We have asked experts to examine the directions the policy should take, given the current era of multipolarity and the geostrategic competition therein. The objective of this series is to help understand the modern threat environment, assess Canada’s capabilities and needs, and provide recommendations for how Canada can address discrepancies across a broad spectrum of its defence and security tools as it updates its defence policy. The release of the articles included in this series will be ongoing throughout the summer of 2022.
