Canadian Civil Aviation - Annual Report
Detailed information for 1999
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 - February 14, 2002 (in Statistics Canada catalogue no. 51-206-XIB).
The survey collects both financial data (balance sheet, revenue and expenses statement) and operating data (e.g.: hours flown, passenger-kilometers, goods tonne-kilometers) 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 the 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.

Data sources and methodology
The universe of the Annual Civil Aviation surveys consists of all Canadian licensed carriers classified into levels I, II, III and IV. These carriers are licensed to perform commercial scheduled and/or charter transportation of passengers and/or goods. Level I includes every Canadian air carrier that, in the calendar year before the year in which information is provided, transported at least 2 million revenue passengers or at least 400,000 tons of cargo. Level II includes every Canadian air carrier that, in the calendar year before the year in which information is provided, transported at least 100,000 but fewer than 2 million revenue passengers or at least 50,000 but less than 400,000 tonnes of cargo. Level III includes every Canadian air carrier that, in the calendar year before the year in which information is provided, have revenues of at least 2 million dollars. Levels IV includes every Canadian air carrier that, in the calendar year before the year in which information is provided, have revenues of less than 2 million dollars.
The Aviation Statistics Centre has written and distributed an instructional booklet for each reporting level entitled, "Guide to the Reporting of Operational and Financial Statistics for Air Carriers". These booklets explain the correct reporting procedures to be followed in the completion of each statement. Since the completed statements submitted by the air carriers contain data at an aggregate, rather than single record level, it is not possible to identify all reporting errors. At the present time, several companies submit internally generated reports and computer listings to fulfill their reporting requirements. However, these reports provide the same information as the regular statements.
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.
Statistical data are collected under the authority of the Statistics Act. No commercial air service may be operated in Canada without a valid license issued by the Canadian Transportation Agency of Canada 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 of Statistics Canada 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.

The publication 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 similiar 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.
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
Annual estimates are provided for the reference year. The data for the previous reference year are revised if necessary. As this is an annual program, 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.
