Diversifying Canadian fighters for Arctic coverage

Canada's larger problem is fighter coverage over the north, where an aircraft such as Gripen is presented as a climate-suited alternative worth considering. A mixed fighter force would cost more to sustain, but it could reduce dependence on a single foreign supplier during an alliance rupture. The requirement would sit alongside expanded maritime-patrol aviation and other northern-security investments. The broader lesson is that sovereignty and supply resilience demand spending beyond the efficiencies available inside a stable alliance system.
