NWT is the place to go. The caribou are always there, although I would suggest the second week of Sept. as being the best. I've been to True North Safaris twice and had a great time both times at their Warburton Bay Camp. By the way this is the place the boys from Traditional Bowhunter usually go to. Frist trip there we saw hundreds of caribou with several stalks a day, the second trip there we saw thousands. Main problem was not getting trampled to death, obviously I'm exaggerating, but they were everywhere. And as stated before the lake trout fishing is fantastic.
