Yes, for example, if you search at Fidelity by CUSIP number, then enter the number, it comes up with Zenith Capital Corp (ZCC).  But, there is no info about that company, so I can't tell which ZCC it's referring to (Calgary or Vancouver).

Zenith will be adding something to their website to say that ZHCLF is not us, so at least we can refer the brokerages to that, and prompt them to follow up with the company.
