West Block

The West Block is one of the three buildings on Parliament Hill, in Ottawa, Ontario. Since 28 January 2019, it has housed the interim House of Commons Chamber, installed to accommodate the House while the Centre Block is closed. The West Block also houses offices for parliamentarians, a branch of the Library of Parliament, committee rooms, and some preserved pre-Confederation spaces.

Built in the Victorian High Gothic style, the West Block has been extended twice since its original completion in 1865. Though not as renowned as the Centre Block of parliament, the West Block appears on the obverse of the Canadian five-dollar bill.
