It's right at the very end if the 400 before you really change to a surface road.
Richardson's Cottage entrance is on the right, near the end of Rte. 400
If memory serves me correct the shelter is on the corner of Emery Road and cornwall Road. I think this is the number you can call if you have any further trouble 1-716-858-8355. Good luck and I hope I was helpful
