Global Headquarters

330 Sussex Drive

Our building is currently closed to the public due to COVID-19. Although tours for visitors are unavailable, we actively encourage people to come enjoy our courtyard with its benches, gardens and heritage views.

330 Sussex Drive in Ottawa  is a Canadian heritage landmark that first housed the Public Archives (1905-1967) and then the Canadian War Museum (1967-2005). It was built between 1904 and 1906 by the Chief Dominion Architect of the time, David Ewart, whose other notable Ottawa buildings include the Royal Canadian Mint and the Canadian Museum of Nature.

The award-winning Canadian firm KPMB Architects led the transformation of 330 Sussex Drive into the Centre’s headquarters. Considerable investments have been made by His Highness the Aga Khan to bring this building back to life with full respect for its important heritage. The Centre officially opened the new facility in May 2017.

Visiting the building and courtyard

Our global headquarters and the surrounding courtyard garden are intended to be welcoming, inviting spaces for reflection and respectful dialogue for the benefit of everyone. We strive to ensure that all those who visit our building and site feel safe and respected at all times.

Land Acknowledgement

We acknowledge that our Centre at 330 Sussex sits on the unceded territory of the Algonquin Anishinaabeg. Unceded, meaning the Algonquin have not given us the rights to be on the land where Ottawa is located. To this day, the Algonquin remain the stewards of this land.

Land acknowledgements such as this remind us of the important process of learning, listening and action that is central for reconciliation and core to pluralism. It reminds us that Canada’s reconciliation process with Indigenous peoples continues, as do processes like this around the world. It reminds us that many societies struggle with the ongoing legacy of colonialism, as do the Algonquin nation. And it reminds us of the importance of understanding and acknowledging history, through narrative and storytelling, to help us make changes towards more inclusive and equitable societies.

History and Revitalization of a Canadian Heritage Landmark

Publication Date: May 16, 2017

Ottawa was named the capital of the Dominion of Canada in 1867 and its transformation from a lumber town to an urban capital was well underway. The decision to build the Dominion Archives at 330 Sussex Drive reflected a growing interest and pride in Canada’s heritage and identity. The facility was part of a broader initiative led by Prime Minister Sir Wilfrid Laurier to transform the capital city of Ottawa into a prestigious destination and a centre for intellectual development. The new public archives at 330 Sussex Drive would be a place for Canada’s historical records to be collected, preserved and studied.

The original wing of 330 Sussex was a three-storey stone building with a central entrance built between 1904 and 1906 in the Tudor Gothic architectural style. In 1925, another wing was built to accommodate the growing collection of archival records. This addition was built at a right angle to the original with the hope that a third wing might be introduced along its north edge as the institution continued to expand.

Many aspects of the building’s design speak to its initial purpose: the large windows provided ample natural light to review documents; several open, undivided spaces allowed for readings tables, shelving and displays; and the fire-proof building materials ensured the protection of historical documents.

When the archives were moved to a new facility, the building was adapted to serve as the Canadian War Museum, with its extensive collection of artifacts, paintings, and war records acquired since 1880. Once again, 330 Sussex was a place for telling the stories of Canadians.

The War Museum’s collection eventually outgrew the facility and, in 2005, the museum moved to its current home on LeBreton Flats in downtown Ottawa.

330 Sussex sat vacant until a partnership between the Government of Canada and the Aga Khan Foundation Canada began a rehabilitation process to transform the building into the Global Centre for Pluralism’s new international headquarters. The building would become a global hub for research, learning and dialogue about the values, policies and practices that advance respect for diversity both in Canada and globally. 

“Let us replace war with peace. Our own commitment is to invest in this building so that it becomes a worthy testament to Canada’s global leadership in the cause of pluralism.”
