BIOAQ is BANKRUPT. The US Bankruptcy has legal supremacy over the CCAA, which has no jurisdiction over the US Company, including the common stock, or the US assets.
Under US Bankruptcy law, the common stock will be cancelled.
And, BTW, it would be cancelled under CCAA, too, as the company has been liquidated. But CCAA can't cancel the common stock, as Canadian courts have no jurisdiction over a Delaware incorporated company. The US Bankruptcy Court will cancel the stock at the conclusion of the US Bankruptcy case.
