The Tuesday night blaze tore through the former Alberta Wheat Pool structure in Sexsmith, about 475 kilometres northwest of Edmonton.
The building hadn't been used for about 10 years and was one of three left in the community that once boasted eight brand new elevators in the 1930s.
Local firefighters and regional emergency crews helped fight the flames that were whipped by a strong wind.
Crews managed to save a number of surrounding buildings, including a historic railway station.
No one was injured and roads around the site were closed as firefighters searched for hot spots. (CJXX)Suggest a correction
