We present a case study of the development of Theories of Systemic Change and Action (TOSCA) in support of the strategy for and evaluation of the Ecotrust Canada Indigenous Home-Lands initiative. TOSCAs add systemic design methods to Theories of Change from the field of program evaluation. They help stakeholders see counterintuitive challenges in the system’s problems they’re addressing and to identify high-leverage strategies for systemic change. We demonstrate the use and value of TOSCAs in a field setting, we provide a case study for future research and education on TOSCAs, and we discuss the challenges and opportunities of this systemic design tool in decolonization and reconciliation.
