All I could find out is that they are in Toronto, Ontario which I'm sure you know. All I can find on eBay are population reports for the big three TPGs. I'm really surprised that a copy isn't easily available.
Copies are not easily available , because the volume produced was quite low to Start with and MOST went to dealers . When I talked to Scott about the 2017 Edition , he honestly stated it was just not worth it . I am willing to bet there are very few 2016 or earlier copies available anywhere! Most are held tightly as research tools .
