then you could take the link 40 that route runs real late and goes by the millenia mall. take it to the Downtown Bus station, from there transfer to the Link 50. that will go to the TTC. make sure to request a transfer when boarding the link 40.
however if you are planng on doing this after fall of 2004 I'm not sure where the routes will go becuase there will be a huge new LYNC CENTRAL STATION. Almost all routes will be affected somehow by the opening of this and we won't know until sept. how they will be affected.
