This statue depicts Alexander Mackenzie, the second prime minister of Canada, and the first Liberal leader to rise to that position.
The cornerstone of Centre Block can be found on the east side of the building.
This rather large monument honours Robert Baldwin and Louis-Hippolyte LaFontaine, both considered Fathers of Confederation (though neither lived to see Confederation enacted). They were co-premiers of the province of Canada (today Ontario and Quebec) starting in 1848, and their work bolstered responsible government and the idea of the colonies taking control of their own domestic affairs. This is the work of Walter Allward, whose masterpiece work was the Vimy Ridge memorial.
George Brown was the journalist, politician, and Father of Confederation who strongly believed in responsible government and argued for Confederation. The sculpture incorporates both English and French translations of the scroll to be found at its base.
