This is a sample survey with a cross-sectional design.
A registry of elevators maintained by the Ontario Ministry of Agriculture, Food and Rural Affairs is updated and provided to Statistics Canada annually. A few elevators are located in Quebec but most are located in Ontario. The survey frame consists of about 250 elevator company headquarters and contains information on the elevator capacity, type of elevator (industrial user, feed manufacturer and country elevator) and contact information. Any elevators licensed by the Canadian Grain Commission are removed from the frame. The frame selected for the December survey is also used for the March and August surveys. The frame is then stratified by type of elevator and by capacity. Industrial users and feed manufacturers are grouped in a take-all stratum. The rest of the sample is selected randomly within each of the four strata. The sample comprises of approximately 100 elevators.
