Canada is actively exploring opportunities to contribute to the Quadrilateral Security Dialogue (Quad) according to its longstanding middle power identity. This chapter examines Canadian inclusion into a Quad Plus formulation. Key lines of enquiry revolve around identifying Canadian middle-power interests in a Quad Plus formulation, capabilities that Canada can bring to the Quad Plus, and how to formulate participation. Findings reveal that Canada’s potential Quad Plus inclusion is based on function over form. Through “bolting-in” and a capabilities-led approach to Quad Plus engagement, Canada strives for functional cooperation wedded to its middle-power identity. Core areas of functional cooperation will include but not be exclusive to enhancing maritime awareness and consensus building of the consultative process through proactive diplomacy.
