Affordable housing was a key issue in the recent 2018 Toronto municipal election. Yet it is important to remember that public health is just as an important issue as affordability, and the science proves that second-hand smoke will travel from one apartment or condo unit to another via cracks, doors, outlets, ventilation, and no existing technology can stop this. In fact, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Position Document on Environmental Tobacco Smoke states the following:
Mixed Occupancy of Smokers and Nonsmokers: If smoking is allowed throughout a space or a collection of spaces served by the same air handler, with no effort to isolate or separate the smokers and nonsmokers, there is no currently available or reasonably anticipated ventilation or air cleaning system that can adequately control or significantly reduce the health risks of ETS (environmental tobacco smoke).
The position document concludes, “At present, the only means of eliminating health risks associated with indoor (second-hand smoke) exposure is to ban all smoking activity.” Furthermore, Cannabis is legal in Canada since October 17, 2018 which means that second-hand smoke exposure in residential buildings may become an even more critical issue. Consequently, as Toronto develops affordable housing lets ensure that it is also smoke-free housing.
