MDA to modernize the Land Title and Survey Authority of British Columbia's Information Solutions and Processes

For immediate release: December 14, 2009

Richmond, B.C. - MacDonald, Dettwiler and Associates Ltd. (TSX: MDA), a provider of essential information solutions, announced today it has signed a contract for over $13.5 million (CAD) with the Land Title and Survey Authority of British Columbia (LTSA) to modernize the LTSA’s existing information solutions and upgrade associated business processes. The contract allows for additional amounts for maintenance and support.

MDA will work with the LTSA to modernize existing information solutions, which support the Land Title and Surveyor General Divisions, including enhancements to land title and survey search and filing functionality. MDA will assist in the development of customer portals for legal professionals and land surveyors that will modernize the way these professionals access the LTSA’s services. Organizational change management services will be provided by MDA to support the planning, training and operational introduction of the LTSA’s new solution. MDA will also provide systems maintenance support for the existing Land Title Register and associated services during the modernization initiative, and subsequently, for the new Land Title Register following deployment.

This contract award signals the continuation of a long and successful working relationship between MDA and the LTSA that began in 1999 with MDA's operation of BC OnLine, where land title instrument transactions represent over 50% of annual volumes. MDA assisted with the development of the LTSA’s Electronic Filing System for land title instruments in 2004, and surveys plans (2004 over Crown Land, and 2008 to the Land Title Register), and continues to maintain the service.

Godfrey Archbold, president and CEO of LTSA said ‘We have complete confidence in MDA as our partner in the LTSA’s business modernization initiative. Increased levels of automation will be introduced and the consistency, accuracy, and efficiency of land title registrations will be enhanced for both external customers and employees. This initiative is essential to meet our service level commitments into the future and to ensure that the LTSA’s business is sustainable from an economic, human resource, and technology perspective.’
