He is Chairman of the
Beaverbrook Foundation and has been a trustee since 1974. In 2003 The Beaverbrook Foundation claimed that 133 valuable paintings in the
Beaverbrook Art Gallery given to the gallery by the first Lord Beaverbrook were not donated, but were instead on long-term loan from the Beaverbrook Foundation. The paintings were estimated to be worth approximately
C$100 million. On 26 March 2007, the arbiter in the case, retired Supreme Court Justice
Peter Cory, ruled that 85 paintings donated to the gallery before opening in the 1950s belong to the gallery, but that 48 paintings transferred after the opening belong to the Beaverbrook Foundation. The arbitration ruling was appealed and a settlement was reached in 2010. Another case between the Beaverbrook Canadian Foundation, chaired by Lord Beaverbrook's son, Max, and the Beaverbrook Art Gallery has also been settled. ==Other activity==
