Those are in western Ontario. Pickering would serve eastern Ontario. Surely you have
a map? It's a 140 km drive between either of those airports and the Pickering Airport Lands.
But what of expanding existing airports in the eastern GTA? There's the Oshawa Executive Airport (YOO), for example, where the runway is longer than that of Billy Bishop and already serves E-Jets. Or the
Peterborough Municipal Airport (YPQ), with its 7,000 ft. runway? VIA Rail's new HSR will run right past this airport and could offer fast service from eastern GTA, Kingston and elsewhere.
