Government House, Regina, Saskatchewan, was constructed as a residence for the Lieutenant-Governor of the North-West Territories, whose territorial headquarters were in Regina until the provinces of Saskatchewan and Alberta were created out of the Territories in 1905 and Regina became the capital of Saskatchewan.
At that point Government House became the vice-regal residence of Saskatchewan, which it remained until 1944 when it was vacated until it was returned to official ceremonial use in 1984.
