To my opinion, the best way to get there - operating year round, cheap, frequent: take the ttc bus 165D from Wilson subway to its last stop, Hwy 400 Car Pool Lot. Buses run Mon-Sat from 5.43am - 24 to 30 mins interval, last bus at 9.51pm. If You will not get a ride north, the last bus 165D back to Toronto runs at 10.54pm. Sunday: they run from 8.50am till 8.10pm - every 32-40 minutes. You can use a free transfer from the subway, and You are supposed to pay extra $0.35 since You travel past the city border.

This last stop is only a FEW METERS from the ramp! THe ramp is in a good place because it is out of the city, yet there is enough traffic on it. This seems to be the best spot to hitch north/transcanada from Toronto.
