The Canadian Headquarters of the Aga Khan, known as the Delegation of the Ismaili Imamat, is situated at 199 Sussex Drive in Ottawa. The Ottawa Imamat itself is a secular building. However, the Aga Khan serves as the spiritual and hereditary leader of the Nizari Ismaili branch of Shia Islam, tracing his ancestry back to Muhammad.

The Aga Khan once noted that, in the West, religion is often viewed separately from social and economic initiatives. In contrast, the Ismaili tradition sees helping the poor and fostering connections between people and cultures as integral to the practice of religion.
Sussex Drive, often referred to as the “ceremonial route,” is also home to the embassies of Kuwait, Saudi Arabia, France, and Japan. The award-winning National Gallery, designed by Moshe Safdie, is located nearby, adjacent to the Canadian Mint and across from the Notre-Dame Cathedral Basilica. Additionally, the Prime Minister’s official residence is located at 24 Sussex Drive, which is currently awaiting renovations.
The arrival of the Ismailis in Canada goes back to Pierre Trudeau, a friend of the Aga Khan IV, invited the Ismaili community to Canada when Idi Amin expelled them from Uganda. Currently, approximately 2,000 Ismailis reside in Ottawa and around 80,000 across Canada, out of a global population of approximately fifteen million.
The architecture of the Imamat left a lasting impression on me during my visit. Designed by the Pritzker Prize-winning Japanese architect Fumihiko Maki, the project originated from a three-page letter from the Aga Khan, in which he requested Maki to design the building. He sought a design concept inspired by the visual qualities of rock crystal, emphasizing its transparency, translucency, and opacity.
Maki and his team carefully analyzed the letter to grasp the Aga Khan’s intentions fully. To gain further insight into the characteristics of a crystal, Maki even brought his wife’s diamond ring into the office to study its reflections from different angles. The Aga Khan’s request was for the building to be mysterious, esoteric, and intriguing, yet aesthetically pleasing, incorporating themes of Islamic architecture.
The Imamat features a large atrium crowned with a multi-faceted dome and includes a courtyard that contains an Islamic garden known as a Char Bagh. Additionally, the building provides office space for the staff of the Aga Khan Development Network (AKDN) and serves as a residence for the Aga Khan when he visits Ottawa.
The AKDN operates numerous educational, conservation, social, and economic programs in Africa and Asia, spending approximately one billion dollars annually. For instance, AKDN founded a university in Karachi, which initially focused on Islamic studies but has since expanded to include liberal arts education. Additionally, the organization has launched a microfinance program designed to support small businesses. This emphasis on helping the less fortunate aligns with the objectives of the Ismaili sect.
Related to the Aga Khan’s interest in architecture, he established a triennial architectural competition for works of Islamic design, including residential, religious, and conservation projects.
The Char Bagh
The purpose of the atrium is to host conferences, meetings, and study groups that focus on improving the condition of humankind worldwide. It features a patterned screen made of cast aluminum that reflects themes of Muslim architecture. The atrium’s floor is composed of maple wood tiles arranged in a seven-square pattern in both directions, with each square approximately ten feet by ten feet. This configuration results in a total of forty-nine squares, symbolizing that the current Aga Khan IV is the forty-ninth Imam of the Nizari Isma’ili sect. The use of mathematical concepts also serves as a symbol in Islamic architecture, reminiscent of the mathematical ratios seen in the gardens of the Taj Mahal.
The three-layered glass dome, composed of panels in various shapes, illuminates the atrium while diffusing direct light through a patterned layer of glass. The glass panels attach directly to the structural frame without the use of hardware. The design of the dome originated in Toronto, with the glass sourced from Austria, the structural steel from Poland, and the panels fabricated in Germany. The construction was completed in Canada. The multi-sourcing of the dome represents “pluralism,” a core principle of Ismaili Shia philosophy.
When I visited the Imamat, I felt relaxed as if I was at home. The parquet-like maple flooring created a warm ambiance, and the filtered lighting was visually soft. The hexagonal pattern of the cast aluminum screens hanging around the walls added a sense of enclosure and intimacy. People were seated around the perimeter of the atrium on large, comfortable couches, enjoying the peaceful atmosphere.
The acoustics in the atrium were excellent, even with many people conversing. The wood floor, screen wall, and triple glass ceiling effectively absorbed sound. The gentle buzz of conversation in this relaxing environment was pleasant, leading me to reflect on the life of Aga Khan IV, who passed away in February 2025.
I learned from the tour guides on the floor that he was born in Switzerland and held citizenship in that country, as well as in the UK, France, and Portugal. He was also an honorary citizen of Canada. In his youth, he was part of the Iranian Olympic skiing team and later earned a degree in Islamic studies from Harvard University. Throughout his life, he became a prominent horse breeder and achieved significant success in business, with his estimated wealth reaching around $12 billion as of 2024.
If you find yourself in Ottawa, I recommend visiting the Imamat not only to appreciate its stunning architecture but also to gain intellectual insight by learning more about the Ismaili community.
