This research report is a local current state review of supports and services available to individuals with intellectual disabilities (IWID), mental health disorders (MHD), and/or criminalized behavior. These individuals can be referred to as complex cases due to the diversity and extensiveness of their support needs. People with intellectual disabilities are a vulnerable population within our society. The addition of a mental health disorder and/or criminal involvement results in further oppression and marginalization of this group of individuals. Due to the complexity of their support needs, the government agencies responsible for providing services and support are struggling to adequately serve these individuals. The Ministry of Social Services, Justice, Health, and the Saskatchewan Health Authority, have joined together in a collaborative task team to address this issue and ultimately develop a new service model to better meet the needs of these complex clients. This document will include an extensive literature review on the factors affecting this population along with identified best practices for supporting complex clients. In addition, a local review of programs and services within the community of Saskatoon will be explored to identify service gaps complex clients face. Finally, recommendations will be made for service development for IWID and complex support needs.
