From the Centre for Equality Rights in Accommodation (CERA):
Environmental Sensitivities and Housing
“Every year, CERA receives a significant number of calls from tenants being made ill from the poor indoor air quality in their apartment buildings. Most of these individuals suffer from environmental sensitivities and are particularly sensitive to contaminants in the air. With funding assistance from the Ontario Trillium Foundation, CERA recently launched HomeSafe, an initiative to educate tenants and multi-unit housing providers on strategies to improve indoor air quality and create healthier living environments.”
The resources section has some excellent documents that are designed to “help landlords, property managers, and co-operative and condominium boards of directors reduce the health impacts associated with multi-unit housing and create living environments that are as safe and “green” as possible… and make their properties more attractive…”
