Thomson has had a long-standing interest in Canada's military and war veterans. In 1995 he narrated a 3-part documentary series about Canada's involvement in international conflicts. On the 90th anniversary of the Battle of Vimy Ridge, in which nearly 3,600 Canadians died, he co-created, with lighting designer Martin Conboy, a commemoration in which the name of each fallen soldier was projected onto the National War Memorial. The following year in 2009, he and Conboy undertook an ambitious project to project the names of the more than 68,000 Canadians who died in World War I onto famous monuments across the country. Projections occurred during the night. In 2010, the Government of Canada honoured Thomson for this effort with a Minister of Veterans Affairs Commendation.^[6]
