Guy Vanderhaeghe is the king of the Canadian west, full of cowboys with high reverence for The Queen.  He has two other marvelous Canadian westerns, available in paperback, The Last Crossing(my favorite), and The Englishman's Boy, both of extraordinary quality, gorgeously written with wonderful Big Sky style plots.  If you love Doig and Guthrie, you will love these marvelous novels from the other side of the Medicine Line.
