What parallel can be drawn between cooperative federalism in US history and current intergovernmental relations within Canada's provinces and territories? Each system is based on complete separation of local and central governments' functions without any overlap. Both systems show overlapping responsibilities between different levels of government for certain policy areas. Cooperative federalism only applies to international relationships, not domestic policies like Canadian provinces interacting amongst themselves. In both cases, lower regions or states don’t hold any substantial power compared to the central government.
