You're approaching the end of Stage One of the Laura Secord Legacy Trail. You'll emerge on to Dorchester Road, along side the railway tracks that run parallel to the trail at this point.
The official end of Stage One is located in the gated car park in Fireman's Park, immediately across Dorchester Road.
Stage 2 of the Laura Secord Legacy Trail continues on the opposite side of the railroad tracks. Cross over the tracks and look for the railway signal control box. The trail heads into the woods, on your right, immediately along side the control box.
