What does the Municipal Government Act (MGA) govern?

The Municipal Government Act (MGA) is primarily concerned with outlining the powers and responsibilities of municipal governments in Nova Scotia. This legislation establishes how municipalities can govern themselves, including their authority to impose taxes, create bylaws, provide services, and manage land use and planning decisions. By focusing specifically on the governance structures and operational frameworks of local governments, the MGA plays a crucial role in shaping the relationship between provincial authority and local municipalities.

The other choices involve topics that fall outside the scope of the MGA. For instance, commercial leasing regulations would typically be covered by property and contract law rather than municipal governance. The authority of provincial schools is managed by separate educational legislation, while environmental protection laws are governed by distinct environmental legislation rather than the Municipal Government Act. Thus, the focus of the MGA solely on municipal authority makes it the correct answer.
