Under the Canadian constitution, criminal law is within the realm of federal authority and anyone violating this provincial statute is therefore subject to quasi-criminal (not full criminal) enforcement under the Provincial Offences Act. The Act is an attempt to codify what was formerly a matter of common law.
Under Canadian legal structure, criminal law is primarily governed by the federal government, while violations of provincial laws fall under the jurisdiction of the Provincial Offences Act, which aims to formalize practices previously dictated by common law.
