Sky-high rent, condo developments, no rent control, evictions and unstable housing are all issues standing in the way of affordable housing in South Etobicoke, Toronto, and major urban cities across the globe. The increase in cost of living coupled with a rise in rent, and stagnant wages, poses threats to those who are facing poverty, health challenges or more disfranchised populations such as students and seniors. What is the cost of living issues for low-income and working-class citizens, and how can a Community of Practice be created to sustain advocacy efforts to support new models for affordable housing through social policy change? The Affordable Housing Needs in South Etobicoke project is a partnership between the LAMP Community Health Centre and Humber College. With this research project we will uncover the cost of living issues through community based participatory research (CBPR) in South Etobicoke to develop a baseline of housing affordability; gather input from community members most marginalized to assess the impact of displacement and further marginalization; identify proactive measures to inform decision-making on issues across the 'cost of living' spectrum; contribute to the fight against homelessness; create inclusive and accessible communities; develop a strategy to co-develop and share possible solutions; and advocate for the building of affordable housing through social policy change.
