Ontario (Toronto bypass): Parry Sound to Sudbury, via Route 69/400
Here is the itinerary for the 153 km route along Route 69 from Parry Sound to Sudbury (a continuation of the route from Toronto to Parry Sound):
The "400" section is the Ontario Highways designation for the portion of Highway 69 already "twinned". Originally (back in the late 1960s) Highway 400 only connected Toronto to Barrie, and has since been extended northwards to roughly Parry Sound.
There is significant work undeway on this stretch of the highway, with construction underway the 25 km from Sudbury to Estaire, and the 11 km from Nobel south to Parry Sound. A short stretch south of Parry Sound, through the Wahta Mohawk First Nation is also in progress. Watch for construction crews during summer travel season in these areas.
The 110 km corridor of the French River drains the rugged Canadian Shield region between Lake Nipissing and Georgian Bay. The river's landscape is largely unchanged since the first Europeans explored it over three hundred years ago to make it a vital link in the fur trade route from Lachine (Montreal) to Lake Superior and the Northwest. The waters vary from narrow, enclosed steep-walled gorges, falls and rapids, to broad expanses of open water.
This river systems has two parks protecting key areas: French River Provincial Park along the 69/400 highway, and Killarney Provincial Park at the French River's Mouth. The river's valley is the habitat for several rare plants (like the Virginia Chain Fern), as well as the Mississauga Rattlesnake. The French River is home to over 40 species of fish, from tiny smelt to popular pickerel/walleye, speckled, brook and rainbow trou all the way to the mighty muskellunge.
North of the French River, you are officially in "Northern Ontario". Before long the highway gets you to Sudbury, where (south of the actual "city") is the Trans-Canada Highway. Head left to go west, or right to go east, or north to head into Sudbury and its shoppign, accommodation and services. Sudbury is a resource town, primarily cickel, but is also the jumping off sport for many industries, lakes and destinations in the area.
