What must municipalities do if they are not part of an agreement under subsection (1)?

If municipalities are not part of an agreement under subsection (1), they are required to enter into an agreement with a board of health or a conservation authority. This obligation ensures that municipalities collaborate with these organizations to uphold health and safety standards in construction and building practices. By forming such agreements, municipalities can access necessary resources, expertise, and oversight that are vital for effectively enforcing the Building Code and ensuring the well-being of the community. This collaboration facilitates compliance with regulations, supports public health, and helps protect the environment, making it a crucial aspect of the legislative framework surrounding the Building Code Act.

The other options do not align with the requirements set forth in the Building Code Act. Conducting inspections without oversight fails to ensure regulatory compliance and public safety, while ignoring the act would contravene legal obligations. Automating sewage system monitoring is unrelated to the requirement for forming agreements with health boards or conservation authorities. Thus, entering into an agreement stands out as the responsible action municipalities must take in this context.
