Louise purchased land from Reggie subject to the condition that subdivision approval be secured. Unfortunately, the contract between them does not specify who is to try to get the subdivision approval. Louise begged Reggie to seek the approval, noting that only the vendor has the information necessary to make the application successfully. Reggie, who had changed his mind about selling the property altogether, is triumphant: "Where does it say in the contract that I have to do anything about making an application for subdivision? Next time, try to be more clear. And in the meantime, our contract is off." Is Reggie obligated to try to secure the subdivision approval? If so, on what basis?
