Trading of certain stocks has been halted and resumed by the Canadian Investment Regulatory Organization, with some outlets reporting resumptions for stocks such as KRY, EM, and USCM, while others indicate ongoing halts for stocks like SGN, PNG.R, and ADZ. The organization has also taken action on other stocks, including lifting a halt on one and extending a suspension on another. The status of trading for some stocks remains unclear due to conflicting reports.
