SUBJECT: Daylight Savings Time change

DATE: February 22, 2007

As a reminder, the start of Daylight Saving Time (DST) will change this year from the first Sunday in April to the second Sunday in March.  As such, Daylight Saving Time will begin on March 11, 2007 and will continue until the first Sunday in November.  Trading schedules will not change; however, the Montreal Exchange would like to remind everyone that all MX Trading Systems will properly recognize the new DST schedule. 

Please address any questions related to this Technical Notice to your Participant Coordinator, or write us at

We thank you in advance for your cooperation.

Thank you,

SAM Participant Connectivity Coordinator
