Which province is mentioned as being responsible for enforcement in territories without municipalities?

The reference to enforcement in territories without municipalities specifically pertains to Ontario, as it has established a framework for building code enforcement that applies not only within its municipalities but also in unorganized territories that lack local government structures. This means that the province itself takes on the responsibility for ensuring compliance with building codes and regulations in areas without municipal governance.

Ontario's Building Code Act and associated regulations provide clear guidelines for how building standards must be upheld, and in regions lacking municipalities, provincial authorities step in to enforce these standards. This centralized approach facilitates consistency and safety in construction practices across the province, ensuring that even areas without local governance are subject to the same building codes as those with municipal oversight.

In contrast, other provinces typically delegate enforcement responsibilities to municipalities or may not have a similar mechanism in place for unorganized territories, which is why Ontario stands out in this context.
