Pursuant to Section 4(1) (a) of the OUR Act, the Office has the responsibility to regulate the provision of prescribed utility services. Various media can be used to fulfil this stipulation of the Act and it is within the purview of the Office, subject to consultation with the affected utility service provider, to determine the most appropriate means of effective regulation. The Office has determined that the regulatory framework, established at the 1999 rate review, is the most appropriate means of continuously regulating the operations of the NWC at the present time and for the foreseeable future.
