Estoppel

The Defence of Estoppel

BMO Nesbitt Burns Inc. v. Wellington West Capital Inc., 2004 CanLII 33776 (ON SC)

[24] To assert estoppel by convention, a party must demonstrate that both parties embarked upon a course of conduct based upon the same premise or assumption. See Amalgamated Investment & Property Co. Ltd. (in liquidation) v. Texas Commerce International Bank Ltd., [1982] 1 Q.B. 84 at 122 (C.A.) per Denning M.R.

Conduct Estopple

[File:2001-CarswellBC-2904.pdf Chernoff Developments Ltd. v. Kent (District), 2001 BCSC 1626]

76 I turn now to the law. Mr. Selinger said that conduct estopple applies to a local Government where there has been a corporate act and the Petitioner has relied on the act to its detriment. He relies on the decision of Levine, J., as she then was, in Gladiuk Contracting Ltd. v. Richmond (City), 1998 CarswellBC 2297 (B.C. S.C.) in which Her Ladyship relied on the decision of Braidwood, J., as he then was, in Harwood Industries Ltd. v. Surrey (District) (1991), 60 B.C.L.R. (2d) 168 (B.C. S.C. [In Chambers]), and applied the principles of estopple by conduct discussed in Litwin Construction (1973) Ltd. v. Kiss (1988), 29 B.C.L.R. (2d) 88 (B.C. C.A.). It will be seen that in my opinion both Gladiuk and Harwood are distinguishable on their facts.

79 After noting that in Harwood Braidwood, J. held that the principle of estopple could apply to Municipalities where there is unfairness or injustice requiring the exercise of judgment, Her Ladyship then cited and followed the following description of estopple by conduct discussed in Litwin at pg. 179: Of course, estopple by conduct has been a field of the law in which there has been considerable expansion over the years and it appears to me that it is essentially the application of a rule by which justice is done where the circumstances of the conduct and behaviour of the party to an action are such that it would be wholly inequitable that he should be entitled to succeed in the proceeding.
