My assumption is that this was seasonal shelter for migrant workers. The accommodations are very rudimentary, a relic of a trailer, plywood shacks, and very few amenities. All the buildings have been vandalized and torn apart, now only housing various animal life. The largest of the structures sits atop sonotube legs with a steel rail frame, presumably to keep it dry in the spring thaw season.
There is a large metal gate at the road which has been cemented in place.
Hard to say the last time this place was used, but judging by the decay, it has been a number of years.
Harder to believe is the sad conditions in which these transient migrants had to live, when not out working the nearby fields in all weather conditions. This area is at the edge of a damp, mosquito-filled forest, not far from the flooding Nottawasaga River.
