Well of course the HSR would use the Weston Sub on its way up to KW the way that GO does already. The elevated spur line off of that corridor and dead-end terminal being constructed for the UPX though would be pretty useless for HSR and would have to be abandoned if UPX itself was replaced by the high speed service.
The airport spur could probably only be used for a people mover from the airport to the railway corridor, or there could even be an extension of the Finch LRT that runs along it and also serves as a airport people mover.
