We have children living in Saskatoon. We have done the trip through Saskatoon to Alaska three times, 2005. 2009, and 2013. I 2007 we went from Saskatoon to Newfoundland by way of Canada with one short dip into Minnesota to the International Wolf Center at Ely, then right back up to Thunder Bay. The drive across Canada was great.
This year we will be going back to Newfoundland, after our visit in Saskatoon, and I have the following route mapped out:
Saskatoon, SK to Yorkton, SK, 205 miles
Yorkton, SK to Portage la Prairie, MB, 227 miles
Portage la Prairie, MB to Vermilion Bay, ON, 249 miles
Vermilion Bay, ON to Thunder Bay, ON, 246 miles
Thunder Bay, ON to Geraldton, ON, 176 miles
Geraldton, ON to Moonbeam, ON, 227 miles
Moonbeam, ON to Temagami, ON, 230 miles
Temagami, ON to Montreal, QC, 182 miles
Montreal, QC, to Quebec City, QC, 157 miles
Quebec City, QC to St Simeon, QC, 110 miles
St Simeon, QC to Baie-Comeau, QC, 149 miles
We don't like to travel over 200 miles a day but this scheduled is mapped out to confirmed campground locations. It will change as we locate additional camping's spots that are not on the map. We just use the schedule for routing purposes, not for time frame.
From Baie-Comeau, QC we will turn north towards the Trans-Labrador Hwy.
My recommendation comes in two parts.
Part one. If you have sufficient time built into your trip schedule to allow an extra 5 to 7 days to travel through Canada then you should take it. It is not as fast as traveling in the USA but is one great drive and adventure. Things a lot of people miss when planning their "Trip of a Lifetime" to Akaka, is that Alaska is not the only destination. The best destination in Alaska is the road getting there. The little extra you expend on fuel is well worth the extra time and money. And if the current exchange rate holds through the summer fuel may actually be cheaper than in the US.
Part Two. Just go. Some routes to Alaska are better than others, but they all get you to Alaska so they are not wrong.
