Bank of Montreal Building (Sir John A. Macdonald Building)

Located on Wellington Street across from Canada’s Parliament Buildings, the former Bank of Montreal building is one of the most prominent and enduring examples of classical architecture in Ottawa. Completed in 1932, this stately structure was originally commissioned as the Ottawa branch of the Bank of Montreal, the country’s oldest bank. Designed by the Montreal architectural firm Barott and Blackader, the building exemplifies the blend of Beaux-Arts symmetry and early Art Deco stylization that defined Canadian institutional architecture during the interwar period.

The structure is clad in Queenston limestone, a stone selected not only for its durability and prestige but for its subtle elegance and natural tonal consistency. The stone was meticulously fabricated and installed to complement the building’s carefully proportioned massing and richly detailed façade. Its fine-grain composition provides the ideal surface for carving, which is evident in the remarkable sculptural program that defines the building’s upper elevation.

Limestone pilasters rise between vertically aligned windows, culminating in a heavy cornice that reinforces the building’s monumentality. Below the cornice, a series of sculpted panels by artist Emil Seiburn depict allegorical scenes drawn from Canadian history, culture, and economy. These reliefs were not merely ornamental but symbolic of the Bank of Montreal’s central role in national development during the early twentieth century. Seiburn’s carvings were executed directly in Queenston limestone, which allowed for crisp lines and enduring legibility in the Ottawa climate.

The building sits on a granite base, anchoring the design in visual strength while providing contrast to the pale warmth of the Queenston limestone above. The interior was once home to high vaulted ceilings, marble floors, and ornate plasterwork, all reflecting the same sense of permanence and trust conveyed by the stone exterior.

In 2005, the Government of Canada acquired the building and began restoring it for parliamentary use. Today, it is known as the Sir John A. Macdonald Building and functions as a ceremonial venue for state functions, official receptions, and high-level meetings. Its continued public use is a testament to the foresight of its designers and the enduring performance of its materials.

Queenston limestone has not only preserved the architectural integrity of the structure over more than ninety years, but it continues to represent the values of legacy, resilience, and national identity. As with many landmark buildings across the country, the choice of Queenston stone was as much about function as it was about cultural symbolism. This project stands among the most important civic commissions to feature our material, and we are proud to have played a role in its enduring legacy.
