If one is cycling up Caledonia Road and want to cycle to Wilson Avenue, they have to detour over to Keele Street or Dufferin Street to reach it. There is a railway that the Barrie GO line uses, but no cycling path parallel to it (yet).
There should be cycling paths about a kilometre apart all over Toronto.
