Air Carrier Operations in Canada Quarterly Survey
Detailed information for fourth quarter 2015
The survey collects both financial data (balance sheet, revenue and expenses statement) and operating data (hours flown, passenger-kilometers, goods tonne-kilometers, etc) from the Canadian air transport industry.
Data release - September 28, 2016
The survey collects both financial data (balance sheet, revenue and expenses statement) and operating data (hours flown, passenger-kilometers, goods tonne-kilometers, etc) from the Canadian air transport industry. The data are used by Transport Canada and the Canadian Transportation Agency for measuring growth and performance of the industry, and the impact of regulatory reform. The information is also used by Statistics Canada as input to the Canadian System of National Accounts and by individual carriers for measuring company performance relative to their competitors.
This statistical activity is part of a set of surveys measuring various aspects of activities related to movement of people and goods. These surveys are grouped as follows:
Transportation by air includes records related to the movement of aircraft, passengers and cargo by air for both Canadian and foreign air carriers operating in Canada as well as the financial and operating characteristics of Canadian air carriers. These data are produced by the Aviation Statistics Centre.
Transportation by rail includes records relating to rail transportation in Canada and between the United States and Canada.
Transportation by road includes records relating to all road transport in Canada. In addition to surveying carriers and owners of registered motor vehicles, certain programs rely on aggregation of provincial and territorial administrative records.
Water Transport includes records relating to water transportation, domestic shipping, international seaborne shipping, and ports of loading and unloading.

Data sources and methodology
The universe of the Civil Aviation surveys consists in all Canadian licensed carriers classified into levels I to VI. These carriers are licensed to perform commercial scheduled and/or charter transportation of passengers and/or goods.
The survey questionnaires comprise financial characteristics such as sources of revenue, expense detail and employment characteristics. Based on contacts with respondents and data users, some modifications have been incorporated into the questionnaires in order to reflect the nature of the industry surveyed. The changes were field tested to ensure that they were reasonable and sustainable.
This survey is a census.
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.
Statistical data are collected under the authority of the Statistics Act and the Canada Transportation Act. No commercial air service may be operated in Canada without a valid licence issued by the Transportation Agency and every air carrier is required to file regular statistical reports on its operations. For purposes of statistical reporting, Canadian air carriers are classified into six reporting levels. The statistical reports are completed by the air carriers at their head office or by accounting firms hired to compile the data on their behalf. The completed statements are mailed to the Aviation Statistics Centre where they are examined for completeness and reasonableness. In cases of incomplete or questionable data, the Aviation Statistics Centre contacts the air carrier by telephone or in writing to obtain missing data, corrections or explanations.

Upon receipt of the participating carriers' completed questionnaires, the data are edited. The edits are performed to check the quality and legitimacy of the information provided. Air carriers must file their data in accordance with the reporting procedures prepared by the Aviation Statistics Centre.
The dissemination of timely data necessitates the development of estimates for missing data. Such estimates are made at the level of the individual air carrier on the basis of observed performance under similar operating conditions. The financial data filed by air carriers during the year are subject to revision when their auditors prepare the annual statements. Thus, from time to time, air carriers notify the Aviation Statistics Centre of revisions to be made to previously submitted data.
The evaluation of the quality of the Quarterly Civil Aviation Survey Statistics includes the comparison with results of other Civil Aviation surveys conducted in Aviation Statistics Centre. For each carrier, number of passengers, available seats, volume of goods carried, total revenue and expenses are compared to comparable statistics collected from the Civil Aviation Monthly (Survey #5026)and Annual (Survey #2713) surveys. The evaluation of data quality also includes systematic cross-references to other surveys conducted in Aviation Statistics Centre as well as to financial and operating information made available publicly by the air carriers.
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.
Data for a specific industry or variable may be suppressed (along with that of a second industry or variable) if the number of enterprises in the population is too low.
Revisions and seasonal adjustment
Quarterly estimates are provided for the most current quarter available. The data for the previous quarter are revised if necessary. Seasonal adjustments are not made to the data.
While considerable effort is made to ensure high standards throughout all stages of collection and processing, the resulting estimates are inevitably subject to a certain degree of error. These errors can be broken down into two major types: non-sampling and sampling. Since the survey is a census of the target population, only non-sampling errors are possible.
Non-sampling errors may occur for many reasons. For example, non-response is an important source of non-sampling error. Population coverage, differences in the interpretation of questions, incorrect information from respondents, and mistakes in recording, coding and processing data are other examples of non-sampling errors.
Non-sampling errors are controlled through a careful design of the questionnaire, the use of a minimal number of simple concepts and consistency checks. Coverage error was minimized by using multiple sources to update the frame. Measures such as response rates are used as indicators of the possible extent of non-sampling errors.
