The CRTC said Thursday it has denied requests from Wind Mobile and the Public Interest Advocacy Centre (PIAC) to review an earlier decision on seamless roaming. In August 2011, the CRTC received applications from Wind (owned by Globalive Wireless Management Corp.), as well as PIAC and and the Consumers’ Association of Canada (CAC), requesting a review of telecom decision 2011-360 on seamless roaming. That decision determined that Rogers Communications Inc. did not grant itself “undue preference” by allowing seamless roaming to customers of its discount Chatr brand but not to Wind customers. Wind argued in its application that Rogers had subjected its subscribers to "an unreasonable disadvantage" that conflicted with section 27(2) of the Telecommunications Act. The company requested that the CRTC require Rogers to negotiate terms with Wind for seamless roaming—in which calls are not dropped when migrating from one network to another—for Wind customers. Rogers argued that its roaming agreement with Wind was identical to agreements with other service providers and that Chatr customers who move off the Rogers network experience dropped calls. The CRTC said Thursday that Rogers did not show an undue preference to its Chatr customers, noting that Chatr is a brand of Rogers on the same network while Wind is a wholesale customer. Wind argued that seamless roaming handoffs were becoming the norm in jurisdictions such as the United States and the European Union. The commission said mandates in other jurisdictions are not relevant and that there is no evidence of other jurisdictions mandating seamless roaming. The CRTC said Wind and PIAC/CAC did not provide evidence requiring an investigation into seamless roaming and said a separate proceeding to examine roaming rules is not necessary.
