This survey collects financial and operational data from the Canadian Level I, II, III and IV air carriers.
Data release - March 26, 2019
Description
This survey collects financial and operational data from the Canadian Level I, II, III and IV air carriers. The data are used by Transport Canada and the Canadian Transportation Agency for measuring the growth and the performance of the airline industry. 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. The information may also be used by Statistics Canada for other statistical and research purposes.
Statistical activity
The survey is administered as part of the Integrated Business Statistics Program (IBSP). The IBSP program has been designed to integrate approximately 200 separate business surveys into a single master survey program. The IBSP aims at collecting industry and product detail at the provincial level while minimizing overlap between different survey questionnaires. The redesigned business survey questionnaires have a consistent look, structure and content. The integrated approach makes reporting easier for firms operating in different industries because they can provide similar information for each branch operation. This way they avoid having to respond to questionnaires that differ for each industry in terms of format, wording and even concepts. The combined results produce more coherent and accurate statistics on the economy.

Data sources and methodology
Target population
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.
Instrument design
The questionnaire comprises 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.
Sampling
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. The carrier level and its main aviation activity are maintained on the Business Register for all Canadian licensed air companies. These specific fields are used to select carriers for each survey and to group them by homogeneous cells.
Data sources
Data collection for this reference period: 2018-05-16 to 2018-10-15
Responding to this survey is mandatory.
Data are collected directly from survey respondents.
Data are collected directly from survey respondents using an electronic or paper questionnaire.
For this survey, almost all data come from collection. Some questions are not directly asked to level I and II carriers but were already asked during the quarterly civil aviation survey (QCAS). So the data from the QCAS are annualized and used in ACAS.

Error detection
A lot of rules have been incorporated in the electronic questionnaire to make sure the submitted data are consistent. Inconsistencies will be corrected during the edit and imputation process. Other inconsistent data can be identified and corrected manually, after verification with the respondent.
Imputation
Various manual methods for imputation, such as donor imputation, ratio analysis and trend analysis are utilized.
Estimation
The survey uses the Generalized Estimation System (G-Est) developed at Statistics Canada to produce its domain estimates and quality indicators. It is a SAS based application for producing estimates for domains of a population based on a sample and auxiliary information. Estimates are computed at several levels of interest, based on the most recent classification information for the statistical entity and the survey reference period.
Population totals and population ratios of totals are calculated, as well as breakdowns by carrier levels. For Level IV carriers, only the total of revenues from reporting carriers are calculated.
Quality evaluation
The Aviation Statistics Centre of Statistics Canada examines the data, verifies the results, does coherence analysis, studies changes across cycles, and compares the results with other sources/surveys.
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.
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
Estimates are provided for the reference year and the previous reference year is revised if necessary. The data are not seasonally adjusted.
Data accuracy
Quality ratings are derived from sampling coefficient of variation and imputation rates.
Coverage rates are evaluated after sampling process.
