This track is used by the 2007 Steelback Grand Prix of Toronto. I found most of the turns by folling the concrete patches that were so slippery this week. They really stuck out. I then confirmed the route with the official website for the race.If you watched the race, but did not know where it happened, check this out.Shown in red.

Notice how it follows a section of parking lot that appears to have been built with the race in mind. You can see white strips on the pavement that appear to be unused by the parking lot layout.Shown in white
