That's actually a pretty tall order Doug.....Trying to find that kind of quality lake trout fishing in northern Ontario is tough, in a fly-in venue at least. The first one that popped into my mind was actually one that Moosebunk referred to. There used to be an excellent camp on Big Trout Lake in far northwestern Ontario, huge, huge lake trout and very abundant. I actually don't even know if it's still in operation, but it was called "Bug River Camp". The beauty of fishing Big Trout Lake is you can fly into the native community on it's shores via small commercial airline, either out of Thunder Bay or Sioux Lookout if I'm not mistaken. Much , much cheaper than chartering a float plane when you're talking that kind of distance. Another option that isn't "exactly" what you're looking for, but the fishing is mind boggling, is Labrador Air Safara (labrador-airsafari.com) out of Baie Comeau in Quebec. From S. Ont., the drive is about the same as going to Nakina and is incredibly senic. They have several camps north of the 52nd latitude that are remarkable fisheries, mostly huge bodies of water that are largely unexplored. What I like about it is it has the best "multi-species" fishing I've found, which equates into the best bang for your buck. These waters have world class lake trout, landlocked atlantic salmon, brook trout and huge northern pike....Now the only downside is this is an outpost camp situation and you'd be on your own (personally that's the way I like it!). I'd be more than happy to offer my personal guiding services if you're thinking about going though!
