Where the predominant purpose of a particular inquiry is the determination of a penal liability (e.g., under s. 239 of the Act), CCRA officials may not have recourse to the inspection and requirement tools in ss. 231.1(1) and 231.2(1). In this regard, "enforcement" in s. 231.1(1) and 231.2(1) did not include prosecution of an s. 239 criminal offence.
