Check Gray Coach Lines history here....https://en.wikipedia.org/wiki/Gray_Coach
Their main intercity routes were from Toronto to Buffalo, where they pooled with GL, and to North Bay and Sudbury were they pooled with GLC. Later on GLC went from Sudbury on to Toronto and Buffalo.
You're confusing the pooling between Toronto, Buffalo, and NYC......
Originally Gray Coach Lines and GLI, were the only carrier's on the route. When the big strike occurred, Gray Coach began pooling with Empire and Adirondack Trailways to reach NYC. When GLI's strike ended, Gray Coach continued pooling with Trailways. So GLI looked for a new way to get their passenger's to Toronto...They went to Trentway-Wager, which put together some of their existing routes to get from Buffalo to Toronto, and now Trentway and GLI offered competition to Gray Coach and Trailways on the Toronto-Buffalo-NYC route.
Later on, GLC acquired Gray Coach Lines, and they continued pooling with Trailways. And shortly after that, GLC and GLI were reunited under common (Laidlaw) ownership.
When that happened, GLC and GLI started pooling one trip together on the route, while the other trips continued the status quo, (GLI-Trentway, and GLC-Trailways).
So some GLI trips from NYC to Toronto went to GLC at Buffalo, and most others went to Trentway. And some GLC trips from Toronto to Buffalo went to GLI, but most to Trailways. Trailways and Trentway never pooled.
Later on, Trentway-Wager became part of the Coach Canada/Megabus operation when acquired by Stagecoach Holdings...
When that happened, they parted ways with GLI, and all GLI trips pooled with GLC, along with Trailways pooling with GLC. Trentway began pooling with Coach USA/Megabus to reach NYC. At about that time, GLI and Trailways began their pooling operation across NY State.....
Trailways and GLC no longer pool, but the GLI - Trailways pool continues....
