Commercial Stocks of Corn and Soybeans Survey (CSCS)

Detailed information for March 31, 2024




3 times per year

Record number:


The purpose of this survey is to collect data on commercial stocks of raw unprocessed corn for grain, and soybeans, stored in grain elevators.


This survey gathers information on stocks intended for use by grain elevators, or intended for sale to grain or oilseed processing operations for human or animal consumption or for industrial use.

The estimates produced will be used in national supply-disposition analyses to verify production and farm stocks. The data are also used by Agriculture and Agri-Food Canada and by grain analysts in the public and private sectors. The information provided may also be used by Statistics Canada for other statistical and research purposes.

Statistical activity

The survey is administered as part of the Integrated Business Statistics Program (IBSP). The IBSP has been designed to integrate approximately 200 separate business surveys into a single master survey program. The IBSP aims at collecting industry and product detail at the provincial level while minimizing overlap between different survey questionnaires. The redesigned business survey questionnaires have a consistent look, structure, and content.

The integrated approach makes reporting easier for firms operating in different industries because they can provide similar information for each branch operation. This way they avoid having to respond to questionnaires that differ for each industry in terms of format, wording and even concepts. The combined results produce more coherent and accurate statistics on the economy.

Reference period: At December 31, March 31 and August 31

Collection period: Collected during the two weeks following the reference period.

Data sources and methodology

Target population

The target population consists of grain elevators, processors, and exporters with stocks of corn for grain and soybeans, as well as industrial users of corn, in Ontario and Quebec.

This is a sample of all known companies that maintain stocks, as determined by the Ontario Ministry of Agriculture, Food and Rural Affairs. It excludes elevators licensed by the Canadian Grain Commission. The total sample size for this survey is approximately 95-100 units.

Instrument design

The electronic questionnaire was designed by Statistics Canada as part of the Integrated Business Statistics Program. This program incorporates business surveys into a single framework, using questionnaires with a consistent look, structure and content.

The questionnaire content was developed by subject matter specialists through consultation with industry experts.


This is a sample survey with a cross-sectional design.

A registry of elevators within Ontario and Quebec is maintained by the Ontario Ministry of Agriculture, Food and Rural Affairs. This registry is updated on an annual basis and provided to Statistics Canada to help establish the survey frame. The survey frame consists of about 250 elevator company headquarters and contains information on the elevator capacity, type of elevator (industrial user, feed manufacturer or 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 at random within each of the four strata.
