Building codes, municipal bylaws, and industry-specific best practice requirements notwithstanding, noise control remains only minimally regulated in Canadian jurisdictions. Disputes about noise disturbance from residential or commercial neighbours fall under the nebulous common law category Nuisance, and even structural noise problems (often due to building design incongruence with purchaser expectations) can prove difficult to resolve. Open to a considerable breadth of interpretation, the parameters of “excessive” noise sometimes require third-party, scientific objectivity when disagreements occur.
