Data release - July 12, 2002


This survey collects data from dairy processors in Canada related to their monthly production and inventory of dairy products. The data are used by Agriculture and Agri-Food Canada, the Canadian Dairy Commission, libraries, provincial governments and the dairy farmers of Canada to assist in the development, administration and evaluation of dairy policies. Numerous government and non-government organizations are involved in the administration of the dairy sector and require detailed information particularly because this sector operates within a supply-management framework that manages farm-level production, imports, exports and prices.

Data sources and methodology

Target population

The universe consists of all dairy processors in Canada.


This survey is a census.

Data sources

Responding to this survey is mandatory.

Data are collected directly from survey respondents and extracted from administrative files.

In all provinces except Prince Edward Island, Alberta, Saskatchewan and Ontario data are collected by the provincial Department of Agriculture, Milk Commission or Milk Marketing Board. These agencies are empowered to audit the purchases and end use of milk processors to ensure that price paid and end use correspond. Milk processors are sent monthly questionnaires, and are required to report all products manufactured, and stocks on hand at the 1st of the month. The provincial agencies then forward their monthly provincial summaries to Statistics Canada, to be incorporated in the Canada total.

Prince Edward Island, Alberta, Saskatchewan and Ontario questionnaires are returned to Statistics Canada for compilation.

Telephone follow-up procedures ensure a high rate of return during data collection.

Error detection

Both monthly reports and provincial totals are scrutinized to ensure that they are consistent with previous periods and industry trends.


Very little estimating is done, since this is a census with very complete follow-up. If necessary, data are estimated for individual plants based on previous months this year, and the same months last year.

Quality evaluation

The survey results are evaluated through comparisons to previous estimates and other sources when available. Biological factors are used as a guide when evaluating the data or comparing to other data sets.

Disclosure control

Statistics Canada is prohibited by law from releasing any information it collects which could identify any person, business, or organization, unless consent has been given by the respondent or as permitted by the Statistics Act. Various confidentiality rules are applied to all data that are released or published to prevent the publication or disclosure of any information deemed confidential. If necessary, data are suppressed to prevent direct or residual disclosure of identifiable data.
