Construction of the museum began in 1905 and took 5 years to complete. The final cost of construction was just under one million dollars, a significant sum at the time. Credit: Library and Archives Canada

During construction, the building began to sink, which caused massive cracks in the facade. In addition, the iconic tower began to lean over and it had to be dismantled before the project even reached completion. Credit: Library and Archives Canada

In order to secure the building, a massive steel exoskeleton was attached to the inside walls of the structure.

The exoskeleton can be seen in some interior areas of the revitalized building.

The massive renovation included the addition of a loading dock, which allows easy access for the museum's artifacts. Previously, all deliveries had to pass through the main entrance.

Two new high capacity elevators were also included in the restoration, making the delivery process much more efficient.

One of the museum's most prized possessions, this 65 foot long skeleton of an adolescent blue whale acts as the centrepiece for the museum's brand new exhibition, The Water Gallery.

The Museum of Nature's collection draws upon over 10 million artifacts from the nation's Research and Collections facility.

The dinosaur exhibit is one of the favourite destinations in all of the museum.

A modern cafeteria and gift shop were also included in the museum's restoration.

Hi-tech board rooms and meeting rooms provide museum staff with ample room to strategize for upcoming shows and exhibits.

The modern design of the lantern juxtaposed with the original facade of the building provides an interesting architectural contrast and hints at the restorative work that was completed.
