It means more ability for competitors to see the costing inputs and therefore call out shenanigans when they happen. This should in theory result in less inflated numbers submitted by the incumbents, and therefore more accurate pricing for wholesale services which in turn would mean more options for consumers.
While this decision isn't applied retroactively to the pending 2012-703 R&V's (ie re capacity pricing), I'm still hopeful that the recent direction of the CRTC will ensure proper scrutiny of the rates in that proceeding. As the rates sit now, particularly on the Cogeco side, they are simply not sustainable now let alone in the future. Alignment of capacity prices closer to where they should be could mean new options like unlimited on higher speed tiers.
It also means that without the silly games that are being played with numbers that future proceedings should hopefully be more streamlined, efficient and result in faster decisions and less appeals.
