The federal government is launching a competition to find a Canadian firm to redesign and rebuild 24 Sussex Dr., the long-neglected official residence for Canada’s prime ministers, which they have been unable to live in since 2015 because of its physical decline.

The winner will be announced on Canada Day in 2027, two government sources told The Globe and Mail.

The Globe is not identifying the sources, because they were not authorized to disclose internal government plans.

They added that the cost of the project will be paid for mostly or entirely through a national, non-partisan fundraising effort led by the Rideau Hall Foundation, a non-profit associated with the office of the Governor-General.

The plan, which the sources said would be announced by Prime Minister Mark Carney on Friday, is aimed at resolving an issue that previous governments have put off dealing with, and addressing criticism about the designated prime ministerial residence being in such poor shape.

One of the sources said the rebuilt house would have security features, but that broader security arrangements would be worked out with the RCMP at another time.
