Toronto to Edmonton next week. Best route?

I can't speak on the route through the United States but for me (home is Regina, Saskatchewan) I would be taking the Yellow Head (Highway 16) from Portage la Prairie to Edmonton. We have had very little snow (except for the Estevan area) and the weather has been spring like for the past week or so. On Hwy.16 you would miss a lot of the snow in the Saskatchewan south east corner. Hwy.16 is a truck route so you'll be driving with the big boys. Please be very careful of black ice - +6 here yesterday and forecast is for +7 today which means lots of water laying around during the day and then freezing at night. Bring plenty of windshield washer and propane as your furnace will not be able to keep up.
Have a safe trip and keep the shiny side up!
