Hunting on GRCA properties in the Cambridge area

I was out for a hike today looking for sheds in the Chilligo conservation area and the adjoining GRCA conservation area by the 401 and Speed river. No sheds but I did bump a few deer. I am wondering if hunting is allowed on this tract of bush? I can't find any information to indicate you can hunt here, yet I found quite a few tree stands in the bush, several shotgun shell casings and evidence of two deer kills - bones and an abundance of hair. Just curious if anyone knows about these areas??

I cant seem to find anything on that tract either. I think most of the grca have signs indicating if hunting is allowed tho
