The hotel that burned in 2014 had been a fixture in the community since 1933.   In the 1930s, Choy Tin Joe applied for a liquor license for the hotel in Elfros.   In 1947, George Kirtzinger from Lashburn, Saskatchewan, and his uncle, Otto Lingle, bought the Elfros Hotel.   George managed the hotel while Otto was away racing horses.   In the fall of 1949, George married Edith Taylor.   They moved to Cudworth to farm for two years and then back to Lashburn with their family of four children.
