Rust Valley Restorations

My wife and I really enjoy the show and the folks in it. However, knowing how reality shows go, I have to ask the Canadians here if:
1. There are really that many old car wrecking yards in that area of Canada?
2. Are there really that many restoration shops in that small of an area?
3. Are the folks in the TV show as likeable in real life as they are on the show?
4. And finally, when they talk “dollars,” they are talking Canadian not US, correct?
