What is the current state of the law on the scope of an invasion of privacy remedy?

In confining its expansion of a remedy from invasion of privacy to situations of intrusion upon seclusion, Sharpe J.A. in Jones v. Tsige noted that (at para. 21): …As a court of law we should restrict ourselves to the particular issues posed by the facts of the case before us and not attempt to decide more than is strictly necessary to decide that case. A cause of action of any wider breadth would not only over-reach what is necessary to resolve this case, but could also amount to an unmanageable legal proposition that would, as Prosser warned, breed confusion and uncertainty.
