Between 1986 and 1991, Théberge and the Museum's Board oversaw the planning and construction of an ambitious new pavilion designed by Moshe Safdie, and launched a fund-raising campaign.
At the same time, Théberge continued to co-curate exhibitions ranging from Leonardo da Vinci (1987), to Japanese art (1989), and even fashion Pierre Cardin (1991).

And he secured a donation from Vancouver philanthropist Michael Audain that, in 2007, saw the creation of a dedicated position for an Indigenous curator at the National Gallery of Canada.
