Last September, we started at Crane Lake on the outfitter's shuttle boat, brief stop for canadian immigration, then to outlet of Namakan River and up-river to just couple hundred meters or so below Lady Rapid.  Our outfitter had arranged for a canadian guy out of Atikokan to pick us up in a van on the north side of the namakan river, and he drove us to the Beaverhouse put-in.  Whole trip took no more than two hours, including canadian immigration--they come right out to your shuttle boat.  It was very, very convenient for our trip and our schedule.  We used Mark Anderson out of Crane Lake; he was sick at the time, but his people were fantastically efficient and helpful.  On the return, his shuttle picked us up near Twin Falls on LLC (northeast inlet, from the Maligne River) and took us back to Crane Lake--less than two hours, even with my son stopping at one of those train-track portages to shop for a souvenir.  Again, very efficiently done.  USA passport check at Crane Lake came right out to our boat; took less than 5 minutes.  I don't know if Anderson had pre-processed us at the two immigration stations or not--it was so efficient, I had a hard time believing they went that quickly, without any advance notice.  Mark's son was driving the shuttle boat, and he was clearly good friends with the immigration folks on both sides, and also with the folks who ran the two train portages.
