If you go on the website, they are good about responding with the rates in detail. You'll likely get a response in a couple of hours.
Woodbine is one of the best tracks for customer service. They even have free programs for harness racing as well as race commentary.
It appeared to me that the rates didn't exactly match up with what I saw distributed and I can't explain the difference. The take is low and the nickel breakage is customer friendly too.
