The Post Office opened on October 15, 1910, and closed on July 4, 1960. When the Canadian Pacific Railway arrived in 1913, the community that used to be named “Barney” became “Retlaw” in honour of Walter R. Baker, a CPR official. “Retlaw” is “Walter” spelled backwards and the community was expected to be a major centre. The town had a CPR railway station, four grain elevators, a hotel, a bank, a blacksmith shop, a pool hall, two churches and several other businesses.
