I called OFAH to see what they had to say about the matter. I ended up talking to a Biologist. That really didn't do my any good; he could only tell me what he "thought".
From what he said, it has to do with the insurance, as mentioned earlier in this thread.
He also mentioned that most hunters who have the mindset to sign up for an OFAH membership are usually up on their hunter etiquette and safety, which makes it less of a liability to have guys/gals like that in the woods.
He also briefly talked about the fact that a hunter killed a person while deer hunting within the last few years, and that caused the county to change some policies regarding hunters on county land.
Still seems like OFAH and Simcoe are looking for a cash grab.. I'll be sticking to my private land from now on.
"Other than deer, what can be hunted in those forests? Grouse? Turkey? Rabbit?" All of those. Some of the forests have swamps, lakes and rivers. There's over 30,000 acres of county land, lost of mixed opportunities for hunting. Hardwoods, Softwoods, fields, Abandoned towns.. Lots of cool placed to hunt.
