3 Min Read OTTAWA, April 15 (Reuters) - Canada’s telecommunications regulator will rule on Thursday on whether reluctant big wireless providers must do more to increase competition in a market that has some of the world’s highest billing rates. Prime Minister Justin Trudeau’s Liberal government is at odds with the telecom operators and ordered them in March last year to bring down cellphone bills by 25% or face consequences. The ruling Liberals want the major firms to offer wholesale wireless access to so-called Mobile Virtual Network Operators (MVNO), smaller outfits that resell the capacity at reduced retail prices and pass on the savings to consumers.
