The museum traces its origins to 1842, when the Geological Survey of Canada began collecting specimens from field expeditions across the country. By 1856, the collection had grown large enough that the Legislative Assembly passed an act creating a proper museum in Montreal. The institution moved to downtown Ottawa in 1881, then into its permanent home - the Victoria Memorial Museum Building - in 1911. Designed to echo the Parliament Buildings just a few blocks north, the museum was envisioned as part of a grand planned capital. The building sits in Centretown, flanked by O'Connor and Metcalfe Streets, its Scottish baronial turrets and Gothic arches giving it the look of a fortress guarding knowledge. Over the decades, the institution expanded beyond geology to encompass all of natural history, renamed the National Museum of Canada in 1927, then the National Museum of Natural Sciences in 1968, before finally becoming the Canadian Museum of Nature in 1990 when it was granted autonomy as its own Crown corporation.

The museum's most dramatic chapter began on February 3, 1916, when fire tore through Centre Block on Parliament Hill. With no parliament building to work from, legislators needed space immediately. The Victoria Memorial Museum Building - massive, fireproof, and centrally located - became Canada's temporary seat of government. For four years, politicians debated wartime legislation where dinosaur fossils normally stood on display. The museum's original central tower was removed during this period to address structural concerns with the building's foundation on the clay soils of the Ottawa Valley. That tower would not return for nearly a century. Between 2004 and 2010, a major renovation replaced it with the Queens' Lantern, a striking glass and steel tower that floods the building's interior with light. The restored museum reopened on May 22, 2010 - fittingly, the International Day for Biological Diversity.

The Bird Gallery alone holds over 500 mounted specimens representing 450 species, their diorama backgrounds painted by the renowned James Perry Wilson. The Mammal Gallery features dioramas by Clarence Tillenius, whose mid-twentieth-century work captures Canadian wildlife with such fidelity that viewers sometimes forget they are looking at art. The Earth Gallery displays minerals, rocks, and geological specimens - including that goodwill lunar sample from the Apollo missions. In the Fossil Gallery, an Edmontosaurus acquired in 1912 became the first dinosaur specimen ever mounted in a Canadian museum, standing on display since 1913. But the most surprising fossil story belongs to Xenoceratops foremostensis: its bones arrived at the museum in 1958, mistaken for a known species. Researchers did not discover the error until the 2000s, when they finally removed the fossils from their original plaster field jacket and realized they had a species entirely new to science - formally named in 2012.

The museum's research reach extends to the Canadian Arctic. The National Herbarium of Canada, housed within the museum's collections, contains over 100,000 Arctic plant specimens - the largest such collection in the country. Researchers have studied Arctic flora since the 1980s, with particular focus on alkali grass, tracking how northern ecosystems respond to environmental change. Early collectors like Erling Porsild and Percy Taverner spent careers building these holdings specimen by specimen. The museum adds roughly 43,000 new specimens each year through fieldwork by staff and collaborators. Major research programs have included excavations of the Foremost Formation for dinosaur remains and the China-Canada Dinosaur Project between 1986 and 1991. The Canada Goose Arctic Experience gallery, opened in June 2017 for Canada's 150th anniversary, displays over 200 specimens and artifacts from the far north. A separate Natural Heritage Campus in Gatineau, Quebec, houses the administrative offices and the bulk of the collection that cannot fit in the public galleries.

From the air, the Victoria Memorial Museum Building is unmistakable - its grey stone mass and the gleaming Queens' Lantern tower sitting south of Parliament Hill in Ottawa's Centretown neighborhood. The museum anchors a stretch of Metcalfe Street that runs due south from the Parliament Buildings, and its grounds interrupt the street grid, forcing traffic to detour around the property. The museum's library and archives hold over 35,000 books, 275,000 photographs, and 1,800 works of art, all housed at the Natural Heritage Campus across the river in Gatineau. For a building that started as a geological storehouse in Montreal, it has become something grander - a place where the full sweep of Canada's natural history, from billion-year-old rocks to Arctic wildflowers pressed last season, is preserved and studied under one roof.
