In 2005, Christina Cameron took up her present position as a Professor in the School of Architecture and holds the Canada Research Chair on Built Heritage at the University of Montreal. Her research focuses on the changing notion of built heritage and the implications of this evolution on heritage theories, processes and practice at the local, national and international level. Specifically, she is documenting the origins and early implementation of UNESCO's World Heritage Convention and examining conservation approaches in Canada from 1950 to 2000.

She has been actively involved in World Heritage as Head of delegation for Canada (1990-2008), Chairperson (1990, 2008) and Rapporteur (1989).
