Monthly Dairy Factory Production and Stocks Survey (DAIR)

Detailed information for May 2017





Record number:


The purpose of this survey is to produce monthly statistics on production and stocks of various dairy products and sales of fluid milk and cream from dairy processors in Canada.

Data release - July 25, 2017


This monthly census collects dairy product data from dairy processing companies, which is required to produce economic statistics for the dairy processing industry in Canada.

Data collected from businesses are aggregated with information from administrative sources to produce official estimates of national and provincial economic production for the dairy processing industry. Survey estimates are made available to governments, associations, and the public.

The data are used by Agriculture and Agri-Food Canada, the Canadian Dairy Commission, 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.

Statistical activity

The survey is administered as part of the Integrated Business Statistics Program (IBSP). The IBSP program 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.

Data sources

Responding to this survey is mandatory.

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

Respondents are contacted by email or letter and given an access code for the electronic questionnaire for the survey, which can be responded to in either official language. Respondents are required to report all data for products manufactured and stocks on hand on the last day of the month.

Administrative files are received from all provinces except New Brunswick and are collected by the provincial Departments of Agriculture, provincial Milk Marketing Boards, and the Canadian Dairy Commission. These agencies are empowered to audit the purchases and end use of milk from processors to ensure that price paid and end use correspond.

Non-response follow-up is conducted via telephone.

The survey, on average, takes respondents 45 minutes to complete.

Administrative data sources are used for the purpose of data collection and are obtained by the Statistics Canada under Section 13 of the Statistics Act.

Data collected at the provincial level from provincial marketing boards is used in place of survey data in order to reduce response burden for respondents. Administrative data is then included with survey data for dissemination.

Data integration combines data from multiple data sources including survey data collected from respondents, administrative data from the provincial departments of agriculture, provincial milk marketing boards, and the Canadian Dairy Commission, and data collected from the Inventory Statement of Butter and Cheese. During the data integration process, data are imported, validated, and aggregated from the different data source providers into the formats, structures and levels required for IBSP processing.
