If you have driven Ontario extensively, you will know that SW Ontario is pretty much a write off.  Straight & flat with only some river valleys to add excitement.  The 2 SW Ontario Pelican Runs on the map were great social events but the roads were certainly not twisties.  The roads are nice Ontario farmland & the routes chosen made them a fun drive, but your arms ain't gonna get too tired from working the wheel.

The Niagara escarpment provides some entertainment to the Western Golden Horseshoe Area.  Although the price is that they are usually pegged at 70 kph.   The Lake Erie & Elora Runs, as well as the Fchat Spring Fling all benefited from this geographic feature.

The Toronto to Oshawa to Lake Simcoe area is a wash due to a virtual sea of SUVs  & minivans & numbingly slow speeds - unless you want to do late night runs on the DVP . . .   As you would expect, the majority of interesting drives are north of Lake Simcoe in Muskoka or well east of Toronto in the Kawarthas or the lake area north of Kingston.

The Fchat Fall route is the best twisty road that I have found in Ontario.  I added an easterly element for My Fall Rennlist Run that was more sedate, but a good warmup & capable of higher speed running certainly.

As you can see, there are a lot of uncharted roads that need to be driven & I am determined to try them all.

Please Note:  These are public roads & not race tracks.  A safe & moderate speed should be maintained at all times.  Depending upon the time of day, you will share the roads with cars, tractors, school buses, cyclists, motorcycles & Mennonite buggies.  Noisy fast cars are a nuisance to many so respect the local populace & be prudent.  And always be safe!
