McMaster purchased a large industrial park three kilometres east of its main Hamilton campus in 2005 with the intention of creating an array of research facilities for the development of advanced manufacturing and materials, biotechnology, automotive, and nanotechnology. In July 2005 the federal government announced it would relocate CANMET, a federal government materials research laboratory, from its Ottawa centre to Hamilton. This decision helped spearhead the development of the McMaster Innovation Park. The United Nations University-International Network on Water, Environment and Health (UNU-INWEH) is headquartered within the park. UNU-INWEH is the only United Nations agency headquartered in Ontario and the only North American host site for a United Nations University, after moving to McMaster Innovation Park on 23 April 2008.
