Lester B. Pearson Building. After Ottawa's amalgamation on January 1, 2001, it was decided that the new municipal government would be based at a new location, Ottawa City Hall. This building was considerably smaller, but was located closer to the city's centre. In 2003, the former city hall was sold to the federal Public Works Department. Today the building mainly houses Global Affairs Canada employees. For several months in 2004, it was the site of the Gomery Inquiry hearings during the Sponsorship Scandal.
