For anyone wishing to trade SASK on CommSec I received the following response regarding linking CommSec to the new ATHA share register in Canada : "Thank you for contacting the International desk regarding your shares. I can certainly help with your email. Generally, the shares get sent back to the Company registry and the new shares are issued via a DRS statement. Unfortunately, CommSec International is unable to accept the stock as it is considered a Micro-Cap stock."
