Maybe not till Monday? The press release said:

"Trading of the Century Shares on the TSX Venture Exchange was halted prior to market open today and such shares are expected to be voluntarily de-listed from the TSX Venture Exchange following the close of markets on October 21, 2011."

Realistically, I think it may even take a day or two longer for brokerages to make the changes in people's accounts. Though you can probably trade them before they show up in the account, if you do it by phone and explain the situation to the discount broker.
