We are planning a trip for late July and part of it we will be going to Toronto. We will be in Wisconsin and may head up to Winnipeg and travel back to Toronto through Canada. I use Goodsams online travel planner to plan a trip and generally I use 400 to 500 miles per day with a goal to drive from 8:00 am until 4:00 maybe 5:00 PM. The issue I see is on CA 17, 421 miles shows 9-1/2 hours of driving. Is 17 that slow and or congested? Any comments or feedback on this leg of our trip would be great.
