PDF Version: Cowper-Smith and the Law of Proprietary Estoppel: Implications for the Oil and Gas Lease?
Case Commented On: Cowper-Smith v Morgan, 2017 SCC 61 (CanLII)
The Supreme Court of Canada handed down its decision in Cowper-Smith v Morgan in December 2017. The decision is an important decision on proprietary estoppel. While it arises in the context of a family dispute it deserves to be read by commercial lawyers including oil and gas lawyers. It is one of the curiosities of the Canadian law of estoppel that some of our leading cases have come out of fact patterns involving the “unless” form of the oil and gas lease from the 1960s and 1970s from Alberta and Saskatchewan. These cases include Canadian Superior Oil Ltd. v Paddon-Hughes Development Co., [1970] S.C.R. 932, 1970 CanLII 3 (SCC) and Sohio Petroleum Co. v Weyburn Security Co., [1971] S.C.R. 81, 1970 CanLII 137 (SCC). These cases continue to be influential in oil and gas lease matters and beyond. The typical fact pattern involves a missed or late payment during the primary term or a missed or late shut-in payment during the secondary term which automatically terminates the lease unbeknownst to either party. The parties continue to act as if the lease is in force and in some cases the lessee expends considerable monies on the leased lands including drilling a new well. But in the end, all is for naught. The lease is dead and to this point estoppel arguments aimed at reviving the lease have largely failed; in some cases on the basis that estoppel cannot be used as a sword (to create a new lease), and in other cases, and most commonly, on the basis that the lessee never acted to its detriment on the basis of a representation made by the lessor that the lease was still in effect; typically there was no such representation, the lessee was simply proceeding on the basis of its own understanding of the legal position.
