Courtsey in YVT (Buffalo Narrows), they have 3 and your min's work, Think they are full for the winter though.
Transwest in LaRonge, but again, don't think they are looking, 7 ho's.
Northern Dene, based in Prince Albert, but CP in Uranium City, (if you get an interview, don't talk about P/U Trucks, bit of a sore spot) They have 5 ho's in the north.
National in YPA have 2.
I've listed in order I think I would prefer.
