Brokers are the ones accusing you of stock fraud, not BCIT.
BCIT did a mandatory Cert pull. All those with valid Certs returned them and have new ones All those who did not return them have invalid certs BCIT consulted a list in which the brokers assigned your name next to invalid certs. BCIT took this list that was provided by your broker and has issued a summons stating that if you cannot prove that you purchased shares legally then you are guilty of securities fraud.
So the Brokers are the ones who are giving false information. The Brokers are the ones pointing the finger at the shareholder. They are the ones who are publicly nobo/obo list stating that you have invalid Certs in your possesion.
Maybe that is why BCIT is allowing you to give back your shares and will still let you go after Your Broker.
