OBOA's vision statement is: "Ensuring a safer and a more sustainable and accessible Ontario by advancing the building official profession." Safety has always been of utmost importance to building officials in Ontario because of the dangers that unsafe buildings present to the public. The newly incorporated values of sustainability and accessibility reflect the progressive expansion of the role of building officials in recent years, as mandated by the Ontario Building Code. According to the legislation, the purpose of the Code is "to establish standards for public health and safety, fire protection, structural sufficiency [i.e., safety], conservation, including, without limitation, energy and water conservation, and environmental integrity [i.e., sustainability] and to establish barrier-free requirements [i.e., accessibility] with respect to buildings."
OBOA expresses its mission as follows: "OBOA supports Ontario building officials in ensuring a safer and a more sustainable and accessible Ontario by delivering training and certification, promoting uniform code application, working with industry partners, providing a voice to policymakers, and advancing the profession." The raison-d'être for the organization is thus to promote the construction of safer and more sustainable and accessible buildings in Ontario. OBOA does this by supporting building officials working for municipalities across the province. By delivering training and certification, facilitating the uniform application of building codes, partnering with related organizations, providing policy input to government and working to advance the building official profession, OBOA demonstrates support for its members and the profession as a whole.
