It is definitly known, I took 5 amps a week of that stuuf last winter...IT SUCKED! It was a definite fake. Ya, I have heard it is a real batch number as well, but I would imagine if it came from Canada it is the fakes. They are being produced here, along with brown amp primos and some others. The HA is still a rumor, no solid evidence. It does make sence though, it would take a good bit of money to do this.
