TSX Markets today announced it has agreed with the POSIT Joint Venture to close the POSIT Canada facility on Toronto Stock Exchange effective Dec. 31, 2004.

In a release, TSX Markets said the facility is being closed because the Canadian marketplace demand and usage does not support the continued operation of the POSIT Canada facility.

In 2001, TSX entered into a software license agreement to use the POSIT software internally in connection with the operation of POSIT Canada for daily matching sessions of TSX listed issues.

POSIT Canada is an electronic order matching system that prices trades at the mid-point of the bid and ask in the continuous market. All orders are completely anonymous and trade reporting shows an anonymous broker number.

POSIT is owned by the POSIT Joint Venture, a joint venture between a subsidiary of Investment Technology Group, Inc. and a subsidiary of Barra, Inc.
