For a one knife selection I would have to give the Alpha the nod with respect to the choices you have offered. I always carry a smaller blade on me and advocate keeping the larger cutting tools close at hand. That being said, the Pork Shank is another knife that really screams utility. Again, it depends on what you'll be doing on your great white north assignment. The flat ground Ratmandu is also rarely a mistake as a really capable do-it-all edc for the bush. If I were headed out, I'd take my trusty Basic 9 and maybe the Dogfather as close second.
Come to think of it, a good 1311 thinned out a bit would be a heck of a chopper. These knives are probably one of the best survival blades that approximate a smaller machete but have the added heft and rigidity. Handles are also comfortable for extended use. So many great options.
Good luck on your trek.
