For readers outside of Canada, Third-Party Internet Access providers are ISPs that purchase wholesale access to the last mile connection from the incumbent telephone and cable providers.
Unfortunately, it looks like prices are going up. Last year, the incumbents were using their flanker brands to undercut the TPIAs, selling service for cheaper than the wholesale prices paid by the TPIAs. In the fall, the CRTC issued an order slashing wholesale prices with years of retroactive repayments to the TPIAs.
Of course the incumbents were angry and they got the courts to suspend the order, and dumped huge filings that will take years to sort through. To influence the politicians, they threatened jobs cuts and cancellation of fibre upgrades in expensive lower density rural areas.
Now, with COVID-19, the incumbents are crying poor, citing increased Internet usage. Sure, the costs are going up, but it's their mobile, TV channels and sports team businesses that are losing revenue. In response, retail Internet prices are going up.
There is a difference between the cheaper and more expensive TPIAs. The wholesale costs have a fixed monthly amount plus a capacity component. The TPIAs have to purchase enough wholesale capacity to support all their customers at times of peak usage. I'm not a Carrytel customer, but I've read reports of slow speeds in the evenings and this would make sense if they were skimping on capacity.
