This tweet sort of explains the uphill battle OC Transpo faces. The transitway gave people a single seat ride right from their door to their office for cheap. It just couldn't scale anymore, but taking it away is the biggest source of backlash. Combine it with the still too frequent train troubles and you can see why outer suburb people are especially livid. People are having a hard time with changes that come with getting into big city territory. While traffic is still easy in Ottawa compared to the GTA, it's now quite common to get into traffic jams outside peak hours, which was something unheard of even a decade ago.
A lot of this is because of the relative shortness of Phase 1. Phase 2 will largely solve the issues for Orleans and Kanata (with all of Kanata feeding into Moodie Stn and Orleans set up in a grid pattern), but Barrhaven will still be the odd man out.
The Transitway's biggest shortcoming was that the highest usage corridor also had the lowest capacity of any corridor on the network.
