Is a contract that requires the purchaser to take all reasonable steps necessary to meet the terms of the contract?

This is specious. The contract was a straightforward example of its kind, negotiated by sophisticated parties. If the wording was not the best, it was good enough for them at the time the contract was negotiated. Although it could have been more precisely worded, it was a clause of the third type referred to by Lambert J.A. in Wiebe v. Bobsein (supra) requiring the purchaser implicitly to take all reasonable steps to do what is necessary. As I have already observed, even if the clause had this latent difficulty there was no practical consequence since the plaintiff fulfilled the terms within the time limits stipulated.
