What I'm saying is that in my opinion it is neither safe nor comfortable riding to Kitchener via mainroads. Since there has been almost no new highway construction in several decades, highways are packed with SUVs, vans and trucks going at high rates of speed. Often the only shoulder is course, loose gravel. If you are satisfied with that, then Google Earth is good. Unfortunately you cannot see the vehicles on the road or see their rate of speed.

The option I gave you is a combo of streets where the speed limit is lower and are residential streets and pathways and railtrails. If I were going to Kitchener by bike that is how I would go. Otherwise I'd rent a car and drive. That's a lot faster and more direct. You probably could get there in about an hour and a half from most places in Toronto.

If you have the time and would like to explore some very pretty countryside my route is best. It is more relaxed, quieter and gives you a real short break from life in the fast lane.
