Looking for route suggestions to go from Toronto area (Durham Region) to Ottawa.
Want the roads to be as silent as possible - don't want to be riding on Highway 7 for very long (or not at all if possible).
Anyone have any favourite routes they can suggest?
I found this, looks like a nice trip http://www.hedney.com/ottawa.htm
Toronto randonneurs club has a route posted at http://www.randonneursontario.ca/routes/tor-pdf/Toronto-Ottawa-Toronto%201000.pdf . I have not personally rode much of it except around the peterborough area. That part of the route is good, and I don't think any of it is on 7.
