"The evidence also suggests that low income Canadians use payphones substantially more frequently than others, and are thus more reliant on payphone service than are higher income Canadians. It is therefore appropriate for the regulator to take action to ensure that payphone service continues to be provided where needed." The Public Interest Advocacy Centre (PIAC) on behalf of Consumers' Association of Canada, the National Anti-the Poverty Organization, and l'Union des consommateurs has filed argument with the CRTC that payphones are in the public interest and should be regulated. PIAC's executive summary of the submission and the final argument filed with the CRTC are both available online.
