By 1907, the town of Selkirk’s original 1876 Post Office was outdated and Winnipeg architect James Chisholm designed an updated structure. The modern structure merged all Dominion offices under one roof including the customs house, fisheries, and North West Mounted Police.

Brown and Garson Construction Company carried out the construction, resulting in the Classical Revival style structure that still stands today. The building features an elaborate cornice and limestone keystones that sit atop the second-floor windows. On the main floor, brick is used to create an intricate three-piece keystone branching off the windows and running the length of the building. On either side of the doorway, engravings in stone proclaim: “CANADA POST OFFICE” and “CANADA CUSTOMS”.

A smooth-cut limestone foundation with small window spaces allows light into the basement. Wooden posts and beams hold up the interior, which feature maple and terrazzo floors and Douglas fir moulding. Each floor has a brick safe, and ornamented cast-iron column are found throughout the building.

In the 1960’s, the building was renovated into a rooming house and today operates as the home of the Selkirk Community Arts Centre, art gallery, and restaurant. It received Municipal Heritage designation in 1990.
