The National Shelter Study is an ongoing analysis of homelessness shelter use trends in Canada. It provides the most reliable national-level estimate of homelessness and is vital for understanding changing trends over time. There are just over 15,400 emergency shelter beds distributed in 400 emergency shelters across Canada. The information used in this study was collected from over 200 shelters across Canada, most of which use the Homeless Individuals and Families Information System (HIFIS). This report updates the National Shelter Study 2005-2014 with new data from 2015 and 2016. While the data show an ongoing decrease in the number of individuals and families using shelters per year, the national occupancy rate remains above 90%. The findings also show ongoing overrepresentation in shelters of people who identify as Indigenous.
