Constable
do you mean this? http://www.openstreetmap.org/directions?engine=osrm_car&route=43.60860%2C-79.68987%3B43.60766%2C-79.68983#map=19/43.60814/-79.69014&layers=N

I cant see any turn restrictions here on the map, there should be no problem to turn left where you want to. Is updated to the latest available version?
thanks
