What Is Building Code?
The Ontario Building Code Act is a legal framework set up by the provincial government to establish minimum building standards, and it applies to any new builds, renovations, or change of use construction. The Ontario building code requirements for renovations are only one of many sections within the act that helps protect you and other people from unsafe building practices, materials, and construction methods.
