A series of interior renovations began in 2002 by the Public Works and Government Services Canada at the direction of the National Capital Commission,^[3] and is concentrated on the Centre Block, West Block, and East Block, Library of Parliament, Confederation Building, and the Justice Building.^[4]

In 2002, an extensive $1 billion renovation project began across the parliamentary precinct,^[5][6][7] specifically focusing on masonry restoration, asbestos removal, vehicle screening, parking, electrical and mechanical systems, and improved visitors' facilities.^[8] The Library of Parliament and Peace Tower, as well as some exterior areas of masonry on the Centre Block have so far been completed, though focus has shifted to the West Block due to its rapidly deteriorating cladding. Before 2018, when the Centre Block is slated to be closed for five years in order to carry out an extensive interior restoration and upgrade, the inner courtyard of West Block will be enclosed and fitted with temporary chambers for the House of Commons. The Senate will move to the Government Conference Centre. ^[8]

In 2007, the government approved an updated Long-Term Vision and Plan to be carried out through a series of five-year programs. Each program includes primary projects to rehabilitate key heritage buildings, urgent building repairs to ensure the ongoing viability of buildings and to address health and safety issues, and planning activities to develop the next five-year program. The first priority as outlined in the Long-Term Vision and Plan is to renovate the core historic Parliament buildings, the triad of the West Block, Centre Block, and East Block. The Centre Block cannot be renovated while it is occupied, its occupants will be relocated and will use the East and West blocks as interim space.^[2] However, these buildings also need rehabilitation work, which will have to be done first. Before this work can take place, however, the functions displaced from the East and West blocks need to be relocated in interim or new accommodation.

In 1988, the East Block 1910 Wing restoration begins. It was completed in 1997.

In 1992, the West Block project receives preliminary approval. The project receives final approval in 1997, is postponed in 1998, and receives revised preliminary approval in 2005.

In 1995, the Centre Block South façade restoration begins. It was completed in 1998.

In 1997, the construction of Centre Block Underground Services rehabilitation begins. It was completed in 1998.

In 2001, the preliminary approval of new construction, the Bank Street Building, was granted. The Bank Street Building construction was cancelled in 2005.

In 2002, the Library of Parliament rehabilitation begins. It was completed in 2006.

In 2005, projects to provide swing space or relocate functions for West and East blocks begin. These projects are ongoing as of 2015.

In 2010, the Wellington Building rehabilitation begins. It was completed in 2016.
