The High Commission of Brunei Darussalam in Canada is the high commission of Brunei Darussalam in Ottawa, Canada. It is currently located in the Sandy Hill neighbourhood at 395 Laurier Avenue East in the building known as Stadacona Hall.

Stadacona Hall was built in 1871 by local lumber baron John Cameron . He did not live in the house long himself, but rented it out to other notables. The first tenant was the Speaker of the Canadian Senate Joseph Edouard Cauchon. The building was named by Cauchon's wife after Stadacona, the First Nations name for their native Quebec City. It then became home to Prime Minister John A. Macdonald and his family who lived their from 1878 to 1883 before moving the Earnscliffe . It later became home to other powerful individuals such as Sir Frederick Borden and William Rowley until after World War II when it was purchased by Belgium and became the home of the Belgian ambassador. In the 1990s downsizing led them to put it on the market in 1995 for $1.7 million. It was bought by Brunei who use it as their High Commission.
