Estoppel Without Regard To Equity? The Puzzling Omission Of Promissory Estoppel’S Inequity Condition In Canada, Marcus Moore

All Faculty Publications

Promissory estoppel plays an important role in enabling the enforcement of promises not made for consideration in cases where the promise was intended to and did induce a party to change its position in regard to preexisting legal rights. However, Canadian law on estoppel has been plagued by confusion and misunderstanding. This article addresses the internationally notable absence of an inequity requirement from promissory estoppel in Canada. The requirement’s absence is peculiar, in that estoppel’s very foundation is in equity, and it must assure that its effect is indeed equitable. Drawing on the Supreme Court of Canada’s decision in Trial …
