But this isn’t a classic contract. It’s a mixture of a contractual analysis and a statutory order by the CRTC.
Rogers and Bell-Aliant are telcos in competition. Rogers has no right at common law to string its wires on Bell-Aliant’s poles, and there is no way in hell that Bell-Aliant would agree to let Rogers string its wires, except at a cost that would make Rogers’ service too pricey for consumers. By getting the infrastructure first, Bell-Aliant has a competitive advantage.
CRTC doesn’t like it when one telco has a built-in competitive advantage from its infrastructure. So it has regulations which require one competitor to share its infrastructure with another competitor, to make sure that consumers have choice of service. It sets out the outline of the conditions for both competitors to use the infrastructure. If the parties don’t agree, or agree on terms that create a duopoly that doesn’t give choice to consumers, CRTC can impose conditions on the terms it’s already set out in its general regulations.
It’s a policy that requires sharing of infrastructure, even if the owner of the infrastructure doesn’t want to, because federal law compels it to do so. That’s not a contract, in the classic sense of a meeting of minds.
And that’s why the SCC decision didn’t have any clauses preserving existing agreements, and why the NBCA said it wasn’t a contract and rejected contract analysis (like frustration). If CRTC lacked any authority to require Bell-Aliant to maintain this arrangement under federal law, because it was power poles, not telephone poles, then the arrangement ceases to have any legal meaning. It’s not a contract, because Bell-Aliant did not freely enter it in the first place, but was required to do so by the CRTC orders. And that is also why the French version entered the analysis, tangentially: was there any hope for Rogers from the French terms and conditions that the CRTC set? (because the CRTC’s orders are valid in both languages)
(Again, lot’s of extrapolation here on my part. I’ve just read the headnotes to the cases. Kids, do not rely on these posts if you are going to start stringing telco wires!)
