Final answer:
The statement is true; the primary aim of zoning by-laws is to enforce the Official Plan, regulating land use and development to ensure uniformity within zones and adherence to the municipality's comprehensive plan.
Step-by-step explanation:
The statement that the main purpose of a zoning by-law is to implement the Official Plan is true. Zoning by-laws are vital tools for municipalities to regulate land use and development of real estate. By establishing zones such as residential, commercial, and industrial districts, zoning regulations ensure that the use of property within each district is uniform and conforms to the community's master plan or official map.
This system promotes orderly growth and protects the public interest by considering public health, safety, and welfare while still balancing property owners' rights.
Land use and zoning are subject to various restrictions to ensure that they are reasonable and not arbitrary. They should relate substantially to the public interest and employ means that are necessary for achieving their goals, according to court decisions. These zoning regulations include limitations on lot frontage, minimum lot area, and the number of dwellings in a specific area. In special zones, like historic districts, additional restrictions may be in place to preserve cultural significance.
