RE:OMNI trades on US OTC as CCTXF (Little known fact)Not sure on that as there has not been any trading in a while. I think this US listing is different as it is a grey market listing. I think when you buy this security on the US they actually by the Canadian shares at the converted exchange rate and the grey exists as a tracking stock. So maybe if they cant do that since in Canada it is halted it wont trade. Last trade was on 4/10/18 !!!!
