BUT, Canadian Brokers are apparently still allowing buy orders. Perhaps the CDN Brokers will join ranks with U.S. Brokers and deny buy orders as well. Perhaps FINRA needs to have a talk with IIROC. Canaccord Genuity is a FINRA member, through its U.S. entity. Whether that affects trading in U.S. stocks in Canada or not, I don't know. https://brokercheck.finra.org/firm/summary/1020
