Ontario to Whitehorse, route advice request.

I wouldn't get too excited about the route, from Edmonton on there really is only one route unless you like traveling dirt roads at 25km/h and have several days of fuel capacity on board your rig. Between Winnipeg and Edmonton there are a couple of routes but they all merge back together again, so they're really just detours.

You're going to take 1 from Winnipeg to just west of Portage la Prairie and get on 16, that will take you all the way to Edmonton.
