Coming from Kitchener/Guelph/etc., your best bet is probably getting off at Bramalea and either transferring to the hourly 34 bus (serves the bus loop going inbound) or walking to Bramalea Road and taking the BT 115 - runs every 30 min Mon-Sat, every hour Sundays.
I can't imagine too many doing either of those....but, for some reason, I can see people going to Malton and extending their train ride by a short bus ride on a dedicated GO Bus shuttle (that said, I still think a more permanent solution would be some kind of people mover extension).
