Homelessness is a systemic problem involving numerous sectors, institutions and agencies and, therefore, requires more integrated system responses in terms of governance, policy and programs. The widespread homelessness experienced in our communities indeed reveals deep structural inequities in our economy and society that ought to be addressed, but also represents a systematic governance failure characterized by a lack of ownership of this issue in and across government. The growing scholarly and practitioner movement towards systems integration thus refers to strategies and frameworks to improve collaboration and coordination between people, organizations and sectors that touch upon homelessness, including some that may not conceive of themselves as directly related to the issue.
