Notice to cdnx.com users regarding Market Depth:

November, 2001

With the acquisition of CDNX by The Toronto Stock Exchange (TSE) in August, a number of initiatives are underway to leverage the strengths of both organizations with a view to providing more effective and efficient service to our customers. As a result, we are currently in the process of integrating CDNX's trading engine technology with the TSE's new trading engine.

In preparation for the migration to the TSE's trading engine in December 2001, CDNX 15-minute delayed Market Depth data will be discontinued on this web site as of November 16, 2001. This affects the Market by Order and Market by Price information that currently appears on the Company Info and Quotes page.

CDNX 15-minute delayed stock quotations will continue to be available from our web site. In addition, CDNX real-time stock quotations and Market Depth data will still be available from the quotation vendors listed below.
