Theoreticaly there aren't Whitetails north of the French River, and you will be north of there. Someone mentioned on another thread there are whitetails in the Red lake area which is due north of Dryden. There is the Loring herd south of Nipising, so I guess there aren't any hard and fast rules.
I hope you don't need guides. I doubt it's difficult to find land to hunt, but then Ontario can be deceptive that way with lots of private ownership anywhere near where people.
Well, hopefuly, having spread the ignorance around someone will now feel required to come in and correct me, and you will get your answer.
Search on the Ontario ministry of natural resource. You should find somone willing to answer your questions.
If you are planing on bringing guns vs say a bow, better start planing that now.
