What are the elements of an unjust enrichment claim?

Kerr v. Baranow, at para. 32, articulates the three elements to an unjust enrichment claim: (1) an enrichment; (2) a deprivation; and (3) the absence of a juristic reason for the enrichment. To obtain a constructive trust as a remedy, the claimant must also demonstrate a “sufficiently substantial and direct” link, “causal connection”, or “nexus” between the party’s contributions and the relevant property, and that a monetary award would be insufficient in the circumstances: at paras. 51-52.
