A bylaw enforcement officer is a law enforcement employee of a municipality, county or regional district, charged with the enforcement of bylaws, rules, laws, codes or regulations enacted by local governments. Bylaw enforcement officers are often out in the community responding to complaints from the public. They often work closely with local police, as well as provincial and federal authorities.
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. Under other denominations, this kind of bylaw enforcement exists in several countries around the world.
