A bylaw enforcement officer (also called municipal law enforcement or municipal enforcement) is an employee of a municipality, county or regional district, charged with the enforcement of local ordinance—bylaws, laws, codes, or regulations enacted by local governments. Bylaw enforcement officers often work closely with police and other law enforcement agencies, but are generally not considered emergency services.
This terminology is commonly used in North America—particularly Canada—and some other Commonwealth countries. In the Canadian province of Ontario, bylaw enforcement officers are generally titled municipal law enforcement officers, and in Newfoundland & Labrador, Alberta and the Northwest Territories, the term municipal enforcement officer is also used. In German speaking countries the term Ordnungsamt, literally translated "Order Office", is widely used. Under other denominations, this kind of bylaw enforcement exists in several countries around the world.
