Moose Jaw City Hall, Municipal heritage property in downtown Moose Jaw, Canada.

Moose Jaw City Hall occupies a building at 228 Main Street North, designed by the J. McDiarmid Company for the Government of Canada as a post office, Royal Canadian Mounted Police station and other federal offices. The City of Moose Jaw bought it in 1965 and converted it into a city hall; the Moose Jaw Police Service headquarters occupies a building attached at the rear.

The structure was built between 1911 and 1914 under architect David Ewart's direction and initially served as a federal government building and post office. Its completion marked an important moment in Moose Jaw's development during a time of economic growth.

The building's name comes from its first role: it opened as a federal post office, with an RCMP station and other government offices, before the City of Moose Jaw bought it in 1965 and turned it into the city hall. The council now meets here at 228 Main Street North.

The building is accessible during standard government business hours if you wish to view the public spaces and architecture. It sits in the downtown core on Main Street, making it easy to locate and visit alongside other nearby shops and services.

The structure was built from Tyndall Stone, a distinctive material containing fossil fragments visible in the stone surfaces. This locally sourced stone makes the city hall an uncommon example of regional building materials employed during its construction.
