my request: https://maps.googleapis.com/maps/api/directions/json?origin=48%20yonge%20street,%20toronto,%20ontario&destination=184%20longhouse%20street,%20woodbridge,%20ontario&key=x&departure_time=1343641500&mode=transit

you want route alternatives, not legs.

use alternatives=true parameter in request
