The National Capital Commission shut down 24 Sussex Drive in November 2022, and nearly four years later, Ottawa still hasn't decided what to do with it.

The NCC, which manages Canada's official Prime Minister's residence, announced the closure on November 17, 2022, citing concerns for staff safety and the need to protect this heritage-designated building. The property has serious structural problems — repair costs are estimated at $36.6 million. Work to remove hazardous materials was scheduled to begin in May 2023, and the building has sat largely vacant and deteriorating since.

Prime Minister Justin Trudeau and his family have been living in Rideau Cottage, a residence on the grounds of Rideau Hall, since 2015. What was supposed to be a temporary move — Trudeau cited the need for renovations when he declined to move into the house after taking office — has now continued through two different Prime Ministers.

The Waiting Game

Ottawa's official line is consistent: the government is working with the NCC on a plan. Public Services and Procurement Canada has told Parliament the property remains closed for health, safety and heritage reasons, and planning work is ongoing. The NCC is clear on its role: it can plan and prepare, but the actual decision belongs to the federal cabinet.

NCC CEO Tobi Nussbaum said in April 2024 that the commission was ready to proceed once the government gave approval. He has also suggested that renewed attention is being paid to the file and that various options are being studied. The language is careful — hopeful but vague on timelines — because that reflects how Ottawa works: the NCC prepares options, but cabinet ministers make the call.

What Options Are on the Table

The $36.6-million estimate covers fixing the building as it stands. But discussions in heritage and policy circles suggest broader possibilities: tearing it down and rebuilding, scaling back the residential space, and opening the grounds more to the public have all been floated. Any significant change faces an extra layer of approval because of the building's heritage status — you cannot simply demolish or alter a designated heritage property without formal process.

Canada maintains official residences for four offices: the Governor General, the Prime Minister, the Leader of the Opposition, and the Speaker. 24 Sussex is the only one currently closed. That matters to how Ottawa thinks about the problem — it is not just about fixing one house but about what standard of living space the Crown should provide the Prime Minister, and how much taxpayers should pay for it.

Why This Matters

The decay of 24 Sussex did not happen overnight. Problems with the building were documented for years before closure. Successive governments deferred spending on it because renovating the Prime Minister's residence makes for awkward headlines — politicians know that taxpayers resent seeing large sums spent on upgrading a government house. That delay has cost money in the long run: the longer a building sits empty and unfixed, the worse it gets, and the repair bill climbs.

There is a practical angle worth noting. A new government has taken office, and sometimes fresh governments find it politically easier to settle files their predecessors left unresolved. More pressing is the arithmetic: the $36.6-million estimate from 2022 has not stayed still. Carrying costs, further damage, and inflation in construction materials tend to push deferred-maintenance bills upward. What might have been affordable four years ago is more expensive in 2026. That simple math — not political will from any government — may be what finally forces the decision.
