Who to report piracy box sellers to?

So I have actually gone around to shops that sell these piracy boxes and I see that they are preloaded with the garbage that Kodi is against. I talk to them about it and one of two things happen.

1) They thank me and they will stop doing it but then I go back and they are still selling them preloaded.
2) They tell me to F off.

Obviously I need to take it to the next level and report them. I talked to the cops already but they can’t do anything without orders from above. I am in Canada so who do I report them to now?

This discussion will also be useful for other people in other countries if people reply with places to report piracy box sellers in their country.
