I wonder if you gave citizens a map of the GTAH and asked them to put pins whether they think transit should converge other than Union, how many pins would land on Pearson. Many, sure, but I'm not sure they even would get a plurality. This discussion is driven purely by the cash that GTAA has access to in the form of passenger fees which allows them to pass cheques to consultants in return for glossy PDFs and branding. And if having a transit hub suddenly didn't suit Pearson because of personal vehicle automation giving higher throughput via 409 etc., those glossy PDFs could quietly disappear because GTAA has no legislative mandate to operate a transit hub, and as a federal entity cannot be obligated to cooperate with Metrolinx/MTO other than when in their own interest.
