RE: Kenora, Ontario??
I do believe that it is only "part" of 7B that requires guides...I will call the local MNR office tomorrow. I do know that nonresidents can not camp at or near most of the roads/highways here.
From what I understand on the nonresidents requirements is a hunting liscence to get your deer tag here, along with an export permit and firearms paperwork.
Hope that helps and I'll keep you informed on the area of 7B that requires guides.
