When were the Parliament Buildings completed?

Discover Canada records this in one direct sentence. The guide writes: The buildings were completed in the 1860s. The Centre Block was destroyed by an accidental fire in 1916 and rebuilt in 1922. The Library is the only part of the original building remaining. The decade the test wants is therefore the 1860s.

The 1860s match Confederation. The Parliament Buildings were completed in the same decade Canada became a country (Confederation in 1867). So the buildings were ready almost immediately as the seat of the new federal government — a physical home for the institutions of the Dominion of Canada.

Most of the original is gone. Discover Canada writes that "the Centre Block was destroyed by an accidental fire in 1916 and rebuilt in 1922." So the buildings standing today on Parliament Hill are mostly post-1916 reconstruction, with one exception: "the Library is the only part of the original building remaining." Visitors today can see the Library as a piece of 1860s architecture preserved within the modern Centre Block.

The Peace Tower came later. Discover Canada writes that "the Peace Tower was completed in 1927 in memory of the First World War." So the iconic Tower at the centre of the Parliament Buildings is not part of the original 1860s construction — it is a 1920s addition. Inside it, the Memorial Chamber holds the Books of Remembrance with the names of soldiers, sailors, and airmen who died serving Canada in wars or while on duty. So the Parliament Buildings as Canadians see them today combine three layers: the 1860s Library (original), the 1922 Centre Block (rebuilt after the 1916 fire), and the 1927 Peace Tower (war memorial added afterwards).

The question is testing whether new citizens know when the Parliament Buildings were completed. Discover Canada commits to one decade: the 1860s. The right test answer matches that.

The wrong answer choices each pick a different decade. The 1850s is too early. The 1870s is too late by a few years. The 1880s is even later. Only the 1860s matches the source — and matches the timing of Confederation in 1867.
