Yawn.....Stock will be canceled, period. CCAA has no jurisdiction over the Delaware based parent co, you know, the one with the trading symbol...with appended Q. Know what that means?

However, once the Stay has been lifted, the pressures that caused the company to initially file for CCAA protection from its creditors will likely return and, accordingly, it is quite likely that the company will be placed into receivership or bankruptcy.
