The mould model by-law, found below, was informed by a comprehensive scan of existing by-laws across Ontario and co-created with the expertise of both public health inspectors and municipal property/by-law officers.  It is now available through the Ontario Association of Property Standards Officers (OAPSO) Model Property Standards By-Law (see by-law 4.16), and is copied here, with permission. 

OAPSO’s updated model by-law on mould in housing can be adopted by municipalities across Ontario to include more robust mould remediation language.  It was developed through active collaboration among provincial professional associations from public health and municipal services, with representatives from the Ontario Association of Property Standards Officers (OAPSO), The Municipal Law Enforcement Officers Association of Ontario (MLEOA), the Ontario Public Health Association (OPHA), the Canadian Institute of Public Health Inspectors – Ontario Branch (CIPHI-ON), the Association of Supervisors of Public Health Inspectors of Ontario (ASPHIO) and RentSafe.
