Mep is right...this forum gets many questions from potential operators and it gets covered over and over. But your questions are not specific enough to really get any kind of help. Take your first quote "looking to build a carwash in Ontario" If you knew a little bit about carwashing and real estate...or had talked to a few carwash equipment providers, you would know your anwser to the area you want to build in (i.e., building in Pickel Lake vs Oakville, is as different as building in NYC vs Burma). Your question is equivalent to "How much is a nice car"?
Now your response to MEP will likely tick off one or more of the best independant sources for carwashing in the world. Not a good start.
