Henry Anthony Conroy was appointed treaty commissioner and conducted the negotiations and signings in 1921.
However, he was unable to gain signatures from some bands in the Liard district during that summer.
Thomas William Harris, the Indian Agent at Fort Simpson, Conroy's replacement, conducted the remaining treaty signings at Liard in July 1922.
The signatories included Bishop Gabriel-Joseph-Elie Breynat of the Apostolic Vicariate of Mackenzie.
Although parts of Treaty 11 lands are in the Yukon, none of the First Nations centered in the Yukon, including Liard First Nation, are linked to any signatories of Treaty 11.
