OTTAWA — Prime Minister Mark Carney is set to announce the government’s plan to “restore” 24 Sussex today.

The 35-room mansion, built in 1896, was abandoned as the official Ottawa residence of the prime minister in 2015.

Taxpayers have since been shelling out tens of thousands of dollars per year to maintain the vacant property.

Heritage Ottawa has said that the building should be maintained, renewed and kept in public hands, even if it’s no longer the official residence.
