Under Delaware law, the seller in an M&A transaction can include a "Great Hill clause", i.e., one designed to preserve the seller's control over the target's privileged pre-closing attorney-client communications.
In particular, the goal is to prevent the buyer from having access to such target privileged communications in connection with any potential post-closing claim by the buyer against the seller.
But are "Great Hill clauses" – named after a 2013 decision of the Delaware Court of Chancery – effective in M&A governed by Canadian law?
Early indications suggest they are, including, most recently, a June 2023 Ontario decision.
Indeed, Canada's largest province is now the country's second jurisdiction to endorse "Great Hill clauses" after Alberta did so ten years ago.
