Data sources and methodology

Target population

The universe is comprised of all companies classified as operating in exploration, development and production of oil and gas in Canada (NAICS 21111) according to the North American Industry Classification System. The target population is those companies found on Statistics Canada's Business Register, classified to NAICS 21111, and whose revenues are above the 10% cut-off threshold used to alleviate response burden (that threshold eliminates all establishments that represent the bottom 10% of the industry total revenues). We are left with a census of all companies above the threshold.

Instrument design

The questionnaire was designed using Statistics Canada questionnaire design standards. The design was done in consultation with the survey's partners. The questionnaire is respondent completed in paper format delivered by mail, fax or in electronic format.

The questionnaires are subject to regular revision to reflect changes in information aspect requirements.


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.

Data sources

Data collection for this reference period: 2014-03-24 to 2014-07-04

Responding to this survey is mandatory.

Data are collected directly from survey respondents.

The data are collected through a mail-out/mail-back process, while providing respondents with the option of telephone or other electronic filing methods. Follow-up procedures are applied when a questionnaire has not been received after a pre-specified period of time: respondents are phoned or sent a fax to remind them to send their questionnaire in order to reach the survey target response rate of 100%.

Error detection

Data processing procedures identify missing data, data entry errors, assess validity of reported data. Macro-level edits detect unusual data fluctuations within a current survey period.


The response rate for this survey is high and as a consequence imputation for non-response is not widely 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 previous year. Other sources of information are also put to contribution, for example, company's annual financial reports.

Quality evaluation

In order to ensure the accuracy and consistency of the data, the results of the survey are reconciled with other information provided by the Canadian Association of Petroleum Producers (CAPP). Other federal departments, provincial and territorial authorities routinely monitor the data.

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.

Revisions and seasonal adjustment

Revisions may be performed for the previous year.

Data accuracy

The survey is a census of the population above the threshold, and the response rate is high (95%). 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 disseminated data are revised.
