The survey covers the scheduled and charter services operated within, into or out of Canada by Canadian and non-Canadian air carriers.
Data release – September 20, 2013
The survey collects data from air carriers operating in Canada. Air carriers are required to file their data via one of three statements, according to their type of operation.
Large scheduled carriers file their data via statement 6. The data are reported in traffic flow format. Data collected includes notably the last stop/next stop, flight number, number of revenue passengers and cargo weight.
Small scheduled carriers file their data via statement 4. Data reported include the origin and destination of passengers transported by the reporting carrier.
Air carriers offering charter services file their charter data via statement 2. Data reported include origin and destination data for passenger and cargo operations.
Transport Canada uses the data for measuring activity at major airports, for evaluating their capacity and for developing an overall planning strategy for Canada's airports. The information is also used by the Canadian Transportation Agency for evaluating the adequacy of air services and by Statistics Canada for providing estimates of provincial passenger and cargo flows.
Statement 6 (also formerly referred to as Daily Airport Activities Report) covers the scheduled domestic and international services operated by the Level I Canadian air carriers. Also included are data from other Canadian carriers and foreign carriers operating scheduled services within, into or out of Canada using aircraft with a maximum take-off weight greater than 30,000 kg.
Statement 4 (also formerly referred to as Coupon Passenger Origin and Destination Report) covers the scheduled passenger services operated by regional and local Canadian air carriers (level II, III, and IV) and the scheduled passenger services by foreign air carriers using aircraft with maximum take-off weight of less than 30,000 kg.
Statement 2 (also formerly referred to as Charter On-Flight Origin and Destination Report) covers Canadian and foreign air carriers that perform domestic or international commercial charter services using aircraft with a maximum take-off weight greater than 15,900 kg. The survey also covers Canadian and foreign air carriers that perform commercial charter services between Canada and United States using aircrafts with a maximum take-off weight greater than 8,200 kg.
The Statements have remained stable over the years, although the format and wording has been modified to maintain its relevance based on feedback from survey respondents and data users.
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 and extracted from administrative files.
Data are collected by Transport Canada under their Electronic Collection of Air Transportation Statistics (ECATS) initiative (see web site: www.tc.gc.ca/eng/policy/ecats-menu.htm)
Statement 6 data are collected daily, weekly or monthly, maintaining the information on flights by actual date.
Statement 4 data are collected quarterly.
Statement 2 data are collected monthly.
Data from all three statements are consolidated into one database and data are disseminated annually.
Upon receipt of the data from Transport Canada, the Aviation Statistics Centre of Statistics Canada applies edit programs to conduct quality checks to determine the quality and legitimacy of the information contained within flight records. Invalid entries are corrected.
Imputation is performed at the level of the individual air carrier on the basis of observed performance under similar operating conditions.
Estimation does not apply to this census survey.
The evaluation of the quality of the Airport Activity Statistics includes the comparison with results of other Aviation surveys conducted in the Aviation Statistics Centre. For each carrier, flight segments, number of passengers, available seats and volume of goods carried are compared to similar statistics collected from the Air Carriers Operations in Canada Quarterly Survey (record number 2712), Canadian Civil Aviation - Annual Report (record number 2713) and the Aircraft Movement Statistics data (record number 2715). The evaluation of data quality also includes comparison to data available from other sources, including the airport authorities.
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.
Annual estimates are provided for the reference year. The data for the previous reference year are revised if necessary. As this is an annual survey, seasonal adjustments are not applicable.
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.
