The Competition Bureau provided details on Thursday on its submission to the Canadian Radio-television and Telecommunications Commission (CRTC), which is conducting a review of wholesale roaming services.

"The Bureau is therefore recommending that the CRTC adopt measures to address the incentives Canada's largest mobile wireless companies may have to raise their competitors' wholesale prices as these increases may be passed on to consumers," it said in a statement.

"The Bureau's submission supports the establishment of regulatory measures if and where they are needed, to ensure that new entrants have access to the wholesale services they need to compete effectively in Canadian mobile wireless markets."
