I was involved in this project too, Ranger definitely had one of the toughest routes.  Wabakimi is a great place.  Here is a brief trip report of my trip (June 17-24).
------------
We did not complete our planned route, on Monday we checked out the
route out of the east end of Takeoff Lake where we were supposed to
go. The park super went through there last September. After the
first portage was supposed to be a bog with a creek to paddle in the
middle. All we found was a pond, two puddles, and a grassy meadow.
A beaver dam had broken and that route was now undoable. Storms and
wind were kicking up so we returned to camp. The next day we tried
to explore the west end of Takeoff, but again wind and rain
prevented us from getting there.

Next we headed into the Metig Lakes and began finding abandoned
Native fishing and hunting camps. These were heavily used up into
the 80s based on the types of trash we found (the evolution of the
soda can was found in the dumps). We spent a lot of time cleaning
two of these. We were supposed to be able to track or paddle the
rapids in the area, but we had to portage. Which meant finding the
long snowmobile trails around the swift water and then clearing
them. We saw 5 moose in these lakes, including one that came into
camp on the night of Sweet and Sour Pork and Walleye.

Finally we made it out to big Greenbush lake and during the Friday
night phone call the sat phone batteries died. So they only had our
approximate location and we only had the friday morning scheduled
time for our rendevouz. Saturday was a lot of waiting, but we were
lucky enough to get a glimpse of a woodland caribou just beyond camp
in the edge of the lake. About 3 hours after we expected them the
plane arrived.

We did not cover a lot of ground, but it was a lot of fun and it was
obvious that this park needs Phil and all of the people that are
helping him. I definitely hope to return.

Here is one of my favorite pics.
