On 4 November 2008, the Queen launched at Canada House in London "Vigil 1914–1918", a coordinated light and media display on the facades of Canada House and buildings in six Canadian cities of the name of each of the approximately 68,000 Canadians who died in World War I; there the Queen and the Duke of Edinburgh met with First World War veterans as well as Canadians returned from Afghanistan. Almost one year later, Prince Charles officiated at the Remembrance Day ceremonies at the National War Memorial in Ottawa, there wearing his uniform as a Lieutenant-General of the Canadian Army.
