I will not give the route for a number of reasons (I personally have ethical reasons and firmly believe that failing for not being able to follow rules of the road makes us safer as a society) but I will give some advice and information.
The town of Clinton is located 2-2.5 hours west of Toronto (take 401 west to Kitchener and Highway 7/8 to Stratford and Highway 8 to Clinton). The town has a population of over 3000 and is 99% white.
It is quite common for carloads of people from Toronto or the GTA to show up to take tests as it is considered easier to pass the test in the small town rather than in the city. I would put the ratio of locals doing their test and people from urban areas like GTA at 50:50.
I have heard a rumour (not confirmed, so consider this hearsay) some of the Drive Test examiners do not like people from the GTA coming to Clinton. Keep in mind the examiner has your license so he/she knows your address. Don't be surprised if they ask you why you are taking the test in Clinton rather than Downsview (or wherever you may be from).
As I stated earlier, I will not give the route. What I will say is that the route is not as easy as it seems and there are a few places that have "obstacles" that will result in instant fail if you do not follow the Highway Traffic Act. Despite being one of the most rural Drive Test locations, Clinton actually ranks in the middle in terms of passing rate. My suspicion is the examiners don't like outsiders taking advantage of the rural test route and may be failing outsiders at a higher rate. Over the past few years, the municipality and province have changed a number of intersections in and around the town. Based on the above, my suggestion is to either become very familiar with Clinton or simply take the test in your hometown as you will already know the surroundings.
No matter what you decide to do and where you take the test, please understand Clinton is a long way to go if you do fail.
Clinton is not the easiest place to do your tests as it is rumoured some examiners don't like outsiders from the city. Although the town is small, a number of intersections can be difficult if you do not follow the rules and signage properly.
