What is the current state of the law of constructive trust in Canada?

I conclude that in Canada, under the broad umbrella of good conscience, constructive trusts are recognized both for wrongful acts like fraud and breach of duty of loyalty, as well as to remedy unjust enrichment and corresponding deprivation. While cases often involve both a wrongful act and unjust enrichment, constructive trusts may be imposed on either ground: where there is a wrongful act but no unjust enrichment and corresponding deprivation; or where there is an unconscionable unjust enrichment in the absence of a wrongful act, as in Pettkus v. Becker, supra. Within these two broad categories, there is room for the law of constructive trust to develop and for greater precision to be attained, as time and experience may dictate.
