Connaught Building Ottawa: Visitor Guide, History, and Architectural Highlights

Date: 04/07/2025

Introduction

The Connaught Building stands as one of Ottawa’s most distinguished heritage landmarks, representing the city’s federal architectural ambitions in the early 20th century. Completed in 1916 and named for Prince Arthur, Duke of Connaught and Strathearn, this imposing structure is a testament to Canada’s nation-building era. Designed by Chief Dominion Architect David Ewart, the building’s Tudor Gothic Revival style—infused with Beaux-Arts symmetry—contributes to its status as a “crown jewel” among Canada’s federal buildings (Glue Ottawa; Parks Canada). Though the Connaught Building now serves as the headquarters of the Canada Revenue Agency and is not generally open for public tours, its striking exterior and central location make it a must-see for architecture enthusiasts and visitors exploring Ottawa’s historic core.

Historical Background

Origins and Purpose

Constructed between 1913 and 1916, the Connaught Building originally functioned as a customs warehouse, handling the inspection and taxation of goods entering Ottawa—especially vital during World War I. Its creation coincided with Ottawa’s transformation into a monumental national capital, and its naming honored the then-Governor General of Canada (Glue Ottawa).

Architectural Vision and Style

David Ewart’s design for the Connaught Building exemplifies the “modified Tudor Gothic Revival” style. The fortress-like sandstone façade, accented by crenellated parapets, turrets, oriel bays, and pointed arches, imbues the building with the gravitas befitting a federal institution. The Beaux-Arts influence is seen in the building’s symmetry and axial planning, aligning it with the nearby Parliament Buildings (Parks Canada; Canada.ca).

Urban Development Role

Occupying a full city block at 555 Mackenzie Avenue (also referenced as 550 Sussex Drive), the Connaught Building anchors Ottawa’s ceremonial governmental district. Its prominent location—opposite Major’s Hill Park and within walking distance to Parliament Hill, Château Laurier, and the ByWard Market—ensures its role as a visual and cultural anchor in the capital (GPSmyCity).

Heritage Designation

Recognized for its architectural and historical significance, the Connaught Building became a National Historic Site in 1990 and is classified as a “Classified Federal Heritage Building”—Canada’s highest level of protection for federal heritage sites (Parks Canada; Doors Open Ontario).

Architectural Features

Exterior Details and Materials

The Connaught Building’s exterior is defined by:

Rusticated sandstone cladding with a granite base and Wallace stone detailing, creating a robust, textured appearance.
Crenellated parapets and turrets along the roofline, emphasizing its fortress-like character.
Tudor-arched windows and doors, ornamental buttresses, and intricate stone carvings, including coats of arms and rosettes.
Symmetrical massing and projecting tower-like pavilions, reinforcing both verticality and grandeur (Parks Canada; Today in Ottawa’s History).

The main entrance, beneath an elaborately detailed tower, serves as the façade’s focal point and is a prime example of Tudor-Revival ornamentation (Canada.ca).

Structural Innovations and Layout

Built with a steel and concrete frame for fireproofing and durability, the Connaught Building originally featured one basement and seven above-ground floors. Renovations in 1971 added two more levels within the existing structure, now totaling eight above-grade floors on the Sussex side. The sloping site allows for unique entry points on Mackenzie Avenue at multiple levels (Wikipedia).

While interior spaces have been heavily modified for modern office use, the exterior remains true to Ewart’s original vision (Today in Ottawa’s History).
