I don't know of any "Tea Pail" portage.  The Bloodvein and Sas waterways, as well as the Gammon west of Stonehouse and the "Africa" portage, are all used and maintained by the Scouts. 

As for route info, that can be tough to put on line, as each Scout trip follows an itinerary planned out by the Scouts themselves ( with some "assistance" by the Charlie Guides).  Each route is custom made by each Scout crew.  Those of us who have worked for the Scout program hesitate to put route suggestions on line, as there are some Scout leaders who will decide a route for the Scouts, then assert that the routes are fixed, set itineraries like what is at Disneymont Philmont.  The Scout Leaders will then refuse to allow the Scouts to plan their own trip, and having the Scouts plan the trip is a central part of the program.  Almost every time, the Scouts come up with trips that are more physically challenging and adventuresome than what the leaders think of as a canoe trip -- and one of the main points is to get the Scouts to take a challenging, rigorous canoe trip, not a fishing trip.   

With Northern tier, there are no set, fixed itineraries.  Plus, some of the names used for portages and lakes are appellations that have been created by the staff at Bissett.  For example, the pair of portages between Stone house Lake and the Gammon river are called "Viet Nam," and the lake in the middle of the pair is called "Africa Lake."  Neither of these are official Canadian names. Same with waterways known as "Mordor," which is the waterway and region directly east from Scout Lake to the Ontario border and Hobbs Lake, and Heartbreak Portage, which is the trail that exits Scout Lake to the immediate NNW.  "Heartbreak" derives its name from the fact that it traverses a swamp, and can take crews 3 to 6 hours to complete.  Scout Lake and Hobbs Lake are official Canadian names, while "Mordor" is not.
