An issuer must disclose material information concerning its business and affairs immediately after management of the issuer becomes aware of the existence of material information, or in the case of information previously known, upon it becoming apparent that the information is material.

But............

"Material Information" is any information relating to the business and affairs of an issuer that results in or would reasonably be expected to result in a significant change in the market price or value of any of the issuer’s listed shares, and includes material facts and material changes.

So there we have it. If the managment didn't expect the Pepsi deal to have an affect on the SP then they don't have to disclose it. Phew, for a moment there I thought maybe a TSX regulation had been broken!
