Linkable File Environment (LFE)
Detailed information for 2014
Through the linkage process the Linkable File Environment (LFE) leverages the single-subject ability of existing surveys and administrative data to inform on business and economic issues. It positions these surveys and administrative data to support longitudinal and cross sectional analysis and offers opportunities, amongst others, to use additional variables to assess entrepreneurship, employment, productivity, competitiveness etc.
Data release - September 30, 2016
The objective of the Linkable File Environment (LFE) 2014 is to update the linked files with the most recent year of available data for the various sources. This will provide a longer series of data for longitudinal and cross sectional analysis.
Governments, academics, international organizations and internal Statistics Canada analysts and researchers use the various variables in the LFE to study firm behaviour. Industry growth in employment, revenues and productivity are topics of interest for policy departments in developing policies on economic development and particularly in targeting programs to the small and medium size businesses. It also allows researchers and analysts to measure the impact of policy programs on targeted groups of firms. Statistics Canada survey managers can also use the LFE for frame development. The LFE is the source of data for the Entrepreneurship Indicators Program.
Reference period: Each data source has its own reference period. Linkages occur every year, to include the most recent data updates.
Collection period: In the data linkage environment, collection periods vary for each data source. Refer to data sources.

Data sources and methodology
The Linkable File Environment contains a complete, up-to-date and unduplicated list of all businesses in Canada based on Statistics Canada's Business Register. The Business Register (BR) contains stratification, collection and response information for Canadian businesses that have a corporate income tax (T2) account, are an employer or have a GST account.
The target populations of the various sources of data used in the LFE are explained in their respective SDDS numbers when available for Statistics Canada products.
This methodology does not apply.
The Linkable File Environment, being an integration of microdata from various data sources, is based on the entire universe of businesses in the Business Register.
The LFE is an environment in which administrative and survey data sources are linked. The data sources, their reference periods, and their survey/statistical program reference numbers (SDDSs) are:

The Business Register (BR), being Statistics Canada's central database for business survey operations, was used as the "base" for matching the other sources of data to obtain a one-to-one record linkage. Deterministic record linkage methodology was used in creating these BR linked files. This ensured consistency with other Statistics Canada business programs and made the linkage process more efficient. Probabilistic matching was used to match the two non-Statistics Canada patent datasets in the LFE.
Depending on the research topic, the variables of interest from the appropriate linkable files are extracted as research datasets and provided to researchers and analysts in a secured and controlled environment at the Centre for the Development of Economic Research (CDER). Analytical and research results are carefully and rigorously monitored and reviewed before release to ensure all confidentiality and disclosure rules are respected.
This methodology type does not apply to this statistical program.
As a data linkage process, the quality of the statistical outputs, which are the linked files created from linking the other source administrative or survey data to the Business Register (BR), is measured by the quality of the matching. High rates of matching of records from the BR to the other sources of data indicate good quality and low rates of matching signify poor quality. To ensure a high rate of matching, the Linkable File Environment (LFE) matching methodology goes through the following steps:
1. Match by Business Number
2. Match by Enterprise Number
3. Match by Establishment Number
The preliminary match of the other sources of data to the BR is performed using the Business Number. Unmatched records are then matched using the Enterprise Number and those that remain unmatched are matched using the Establishment Number. Records that remain unmatched after these three steps are investigated by manual review through matching to the BR by business name or by consultation with the personnel from the area where the file was created or by consultation with the Business Register Division.
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
Data available in the LFE are subject to revision if the source data and/or methodologies used are revised. Consequently, the newest version of the LFE would include revisions emanating from the sources. There are no seasonal adjustments performed on the microdata used in the Linkable File Environment.
Since the Linkable File Environment (LFE) is a data linkage of several administrative and survey data to the Business Register, it does not produce statistical estimates for which errors can be provided. Instead the (LFE) provides an indication of the match rates (99.82% in 2014), which show the extent to which the records from the surveys or administrative data sources are matched to the Business Register.
