The CRTC recently released Regulatory Framework for Voice Communication Services using Internet Protocol (Decision 2005-28), Telecom Decision CRTC 2005-28, setting out the details of the appropriate regulatory regime applicable to the provision of VoIP services. We present a brief overview of Decision 2005-28, we then consider the positions of incumbents and competitors, and finally we comment on the above interventions in light of the economic theory of regulation and the theory of strategic competition. We conclude that the predominant model underlying the positions not only of the CRTC but also of the parties involved, including the firms themselves, both the incumbents and the new entrants, and their respective business consultants, do not stand the test of modern economic theory.
