This monthly survey collects data on the activities of all Canadian refineries involved in the production of refined petroleum products and of selected major distributors of these products. This data is required for integration into the input-output sector of the Canadian System of National Accounts. Data is made available under the authority of the Statistics Act to other federal departments and provincial authorities through data sharing agreements subject to embodied principles of data confidentiality. Data is intended for use by survey respondents, industry associations, industry analysts, the press and the general public to assess trends in the Canadian refining sector.
Reference period: Month
Collection period: Data collection is conducted on a monthly basis - 1 to 15 days following the end of the survey reference month.

Data sources and methodology
The universe is comprised of all refiners and major distributors of refined petroleum products in Canada. The list of survey respondents is updated regularly to ensure a total coverage of refining operations and a sufficiently wide coverage of major distributors of these products. Industries covered include those classified to the North American Industry Classification System (NAICS 2007) sub-sector 324 Petroleum and Coal Products Manufacturing comprised of establishments primarily engaged in transforming crude petroleum and coal into intermediate and end-products. It also includes industries in sub-sector 412 Petroleum Product Wholesaler-Distributors comprised of establishments primarily engaged in wholesaling crude oil, liquefied petroleum gases heating oil and refined petroleum products.
The questionnaire is respondent completed in paper format delivered by mail or fax. Data is also transferred in an electronic format by e-mail. The survey uses two types of questionnaires - a long-form directed to refineries and a short-form to distributors. The difference between the two questionnaires is that distributors are not questioned regarding refinery operations. The questionnaires are subject to regular revision to reflect changes in refinery operations such as the introduction of new products i.e. low-sulfur diesel and heavy fuel production in 1998.
This survey is a census with a cross-sectional design.
Data are collected for all units of the target population, therefore, no sampling is done.
Responding to this survey is mandatory.
Data are collected directly from survey respondents.
The data is collected by an annual mail-out of 12-monthly questionnaires. Questionnaires are completed and returned on a monthly basis. The annual mail-out includes a Survey Reporting Guide. Survey follow-ups are conducted as needed by telephone and fax to reach the survey target response rate (100% per month).

Data processing procedures identify missing data, data entry errors, assess validity of reported data and determine input/output balances for each survey respondent and transactions (or transfers) between respondents. Macro-level edits detect unusual data fluctuations within a current survey period. Survey results are routinely reconciled with other energy surveys such as the Monthly Oil Pipeline Survey Transport 'A' (Survey ID 2148) and the Quarterly Industrial Consumption of Energy Survey (Survey ID 2166).
The response rate for this survey is 100% and as a consequence imputation for non-response is not normally required. However on occasion some respondents may be unable to respond or may be late in responding. In such cases missing data is automatically imputed based on historical information, for example, data from the same month of the previous year.
In order to ensure the accuracy and consistency of the data such as the inter-provincial movements, imports and exports of crude oil and deliveries to refineries, the results of the survey are reconciled with other energy surveys. These surveys include the Monthly Oil Pipeline Transport 'A' Survey and the Monthly Oil Pipeline Statement (Survey ID 2191). Other federal departments, the National Energy Board, provincial and territorial authorities and international organizations such as the International Energy Agency routinely monitor the data.
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.
Confidentiality analysis includes the detection of possible direct disclosure, which occurs when the value in a tabulation cell is composed of a few respondents or when the cell is dominated by a few companies.
Revisions and seasonal adjustment
Revised data is incorporated into the database up to 12-months after the current reference month. Major revisions are incorporated as required.
The survey is a census of the target population and the survey response rate is normally 100%. As a consequence, under-coverage is minimal, and minimal bias resulting from non-response is introduced. If changes are received from respondents, the data are incorporated and the published data are revised.
