s 17 Secure electronic record
17.—(1) If a specified security procedure, or a commercially reasonable security procedure agreed to by the parties involved, has been properly applied to an electronic record to verify that the electronic record has not been altered since a specific point in time, such record is treated as a secure electronic record from such specific point in time to the time of verification. (2) For the purposes of this section and section 18, whether a security procedure is commercially reasonable must be determined having regard to the purposes of the procedure and the commercial circumstances at the time the procedure was used, including —(a) the nature of the transaction; (b) the sophistication of the parties; (c) the volume of similar transactions engaged in by either or all parties; (d) the availability of alternatives offered to but rejected by any party; (e) the cost of alternative procedures; and (f) the procedures in general use for similar types of transactions.
