Great job fellas! Canada is truely an adventure rider's paradise!
I could likely assist (as time allows) with some of the Prairie sections as well. Originally from Sask, I have spent much time working across Western Canada in the petroleum sector, travelling many backroads by pickup (and bike). Sask and Alberta have many gravel/dirt routes that travel across both the open prairies in the south, as well as the forested north. I am assuming you are open to more than one route?
My other ride is a horse.......no, really.
