The objective of this 2005 study was to develop a framework for the cost benefit analysis of two programs of Canada Mortgage and Housing Corporation, including all effects on applicants, their caregivers and their community. The two programs are the Home Adaptations for Seniors Independence Program (HASI) and Residential Rehabilitation Assistance Program for Persons with Disability (RRAP-D). This paper includes cases studies and lessons learned in developing two methods for measuring cost-benefits. It also lists all the costs and benefits that might be relevant and discusses how each might be measured. CMHC has a library of publications and resources.
