1. Introduction

Statistics Canada, in collaboration with the provinces and territories, Employment and Social Development Canada (ESDC), and other stakeholders, has developed the Education and Labour Market Longitudinal Platform (ELMLP).

The ELMLP allows longitudinal integration of administrative data related to education with other data sources to provide customized datasets for analytical purposes.

The ELMLP Program fills data gaps and enables a greater understanding of student and apprenticeship pathways, transitions to the labour market and outcomes over time.

Data from the ELMLP can help address a wide range of policy questions pertaining to student and apprenticeship persistence, completion, mobility and pathways as well as their labour market outcomes.

These data allow policy makers to understand the different types of trajectories that students can take through their postsecondary education or apprenticeship training as well as student characteristics that may be related to these trajectories.

The target audience for the ELMLP includes provincial ministries of education, apprenticeship authorities, postsecondary institutions, federal government departments, members of the academic community, researchers, students and parents interested in graduate outcomes and other stakeholder groups involved in education and the labour market.

2. The Education and Labour Market Longitudinal Platform (ELMLP)

2.1 The key features of the ELMLP

  1. Platform – The Platform allows researchers to unlock information about past cohorts of college/university students and registered apprentices, to better understand their pathways and the ways in which education and training affected their career prospects.

  2. Securely integrated datasets - These integrated datasets allow us to know more than what a single dataset or survey can provide. Integrated datasets means that all of the datasets in the ELMLP may be linked with each other using an anonymous linkage identifier located on each file. After identifying which ELMLP datasets are needed to answer a specific research or policy question, researchers can use the anonymous linkage identifier located on each file to bring these datasets together. The integration of datasets is carried out within the Statistics Canada Social Data Linkage Environment (SDLE), which maintains the highest privacy and data security standards.

  3. Longitudinal data – The data available within the Platform are linked longitudinally, allowing researchers to better understand the behaviours and outcomes of students and apprentices over time.

  4. Accessible data – All datasets prepared for the Platform are made available to researchers through the Research Data Centre network across Canada.

2.2 Accessibility, confidentiality and privacy

The integrated datasets in the ELMLP are deemed sensitive statistical information and subject to the confidentiality requirements of the Statistics Act. Statistics Canada employees who build the integrated datasets for research purposes have access to the data only after it has been stripped of personal identifiers. Furthermore, only Statistics Canada employees and deemed employees who have an approved need to access the data for their analytical work are allowed access to the linked analytical files

These data are treated with the same level of confidentiality as surveys administered by Statistics Canada.

Findings from the ELMLP are released through Statistics Canada’s website.

The ELMLP data are also available in Statistics Canada’s Research Data Centres (RDC) to researchers with approved projects only. These researchers will be provided with access in a secure setting at the RDCs, which are staffed by Statistics Canada employees. The RDCs are operated under the provisions of the Statistics Act in accordance with all confidentiality rules, and are accessible to researchers once they have been sworn in under the Statistics Act as “deemed employees.”

2.3 Core and supplementary datasets

The ELMLP consists of two types of datasets: core and supplementary.

Core datasets are updated in the ELMLP on an annual basis and include:

  1. The Postsecondary Student Information System (PSIS) - an administrative dataset of all Canadian public college and university enrolments and graduates by type of program and credential, and field of study for each reporting year. The ELMLP includes PSIS data from 2009 onwards for all provinces and territories, as well as from 2005 onwards for the four Atlantic Provinces and from 2004 onwards for Alberta.
  2. The Registered Apprenticeship Information System (RAIS) - an administrative dataset of all Canadian (provincial and territorial) annual data on registered apprentices and trade qualifiers. The ELMLP consists of RAIS data from 2008 onward.
  3. Income tax from the T1 Family File (T1FF) - select information from income tax data from 1992 onwards is available for all PSIS and RAIS records that were linked to the T1 Family File. 

Supplementary datasets are additional datasets that are being integrated into the platform in order to add new indicators for research purposes. Over time, the number of supplementary datasets that are brought into the ELMLP will grow and could include survey data already collected by Statistics Canada, administrative data already obtained by Statistics Canada, and administrative data not yet available at Statistics Canada. The list of ELMLP files currently in the RDCs can be found by typing “ELMLP” in the Filter Items window.

3. Data sources

3.1 Data sources and record linkages

The Registered Apprenticeship Information System (RAIS) is the foremost source of information on apprentices in Canada. On an annual basis, RAIS produces cross-sectional statistics on registrations in apprenticeship programs and certifications in trades. The cross-sectional annual RAIS files are not structured to support longitudinal studies, and they do not contain information on apprentice and trade qualifiers employment incomes.

The annual RAIS files were linked longitudinally to themselves to produce longitudinal indicators on apprenticeship training. Those files were then linked to the T1 Family File to produce indicators on apprentices and trade qualifiers employment incomes.

Probabilistic record linkages were conducted in the Social Data Linkage Environment. Successful linkages were dependent on the completeness of personal identifiers available in the RAIS files. Nearly 99% of the records in each of the RAIS files were successfully linked to Statistics Canada’s Derived Record Depository. 

For more information on record linkage, visit the Social Data Linkage Environment (SDLE). For more information on tax data, visit the T1 Family File.

The Registered Apprenticeship Information System (RAIS), Apprenticeship Grants, Canadian Apprenticeship Loans, Ellis Chart, jurisdictional websites, and other data sources are linked to determine the classification of each trade as Red Seal or non-Red Seal by jurisdiction. As such, trades in certain jurisdictions may not contribute to national Red Seal or non-Red Seal totals. Additionally, not all Red Seal trades receive Red Seal endorsement in all jurisdictions, however data for these trades are still processed as Red Seal for comparison purposes.

3.2 Concepts derived from the Registered Apprenticeship Information System

The reference period for the annual RAIS file is the calendar year.

Designated trades are trades for which apprenticeship training and trade qualifications are available in Canada. These trades are governed by provincial and territorial jurisdictions, who determine the trades for which apprenticeship training is made available and certificates are granted. The jurisdictions also determine which designated trades require certification in order to work unsupervised in the trade.

Journeypersons, for the purposes of these indicators, are defined to be individuals who completed an apprenticeship program or trade qualifiers who have received a certificate of qualification.

Individuals who completed an apprenticeship program were registered apprentices who certified through a trade program. Registered apprentices are individuals in a supervised work training program in a designated trade within their provincial or territorial jurisdiction. The apprentice must be registered with the appropriate governing body (usually a ministry of education or labour, or a trade-specific industry governing body) to complete the training.

Trade qualifiers are individuals who meet the on-the-job experience required to qualify for certification within a jurisdiction, without necessarily having completed an apprenticeship program.

Red Seal programs have common standards to assess the skills of tradespersons across Canada in specific trades, referred to as the Red Seal trades. Tradespersons who pass examinations to meet these standards receive a Red Seal endorsement on their provincial or territorial trade certificates. The Red Seal endorsement certifies tradespersons to work in their trade in any province or territory, whereas other forms of certification may only be recognized by certain provinces or territories.

Non-Red Seal trades do not have interprovincial standards. Many of these trades do not have an examination requirement in order to work in the trade. Five non-Red Seal trades are selected to account for female-dominated trades; child and youth worker, developmental service worker, early childhood educator, educational assistant and esthetician.

Certifications are required to work unsupervised in a number of trades in Canada. Requirements for obtaining such a designation vary widely across jurisdictions as well as across the trades themselves. In most instances, apprentices are issued a certificate if they completed requirements such as supervised on-the-job training, technical training, as well as passing one or more examinations. Meanwhile, trade qualifiers become certified once they pass an examination.

Here is the complete list of concepts used by the Registered Apprenticeship Information System (RAIS).

3.3 Confidentiality and rounding

All data are subject to the confidentiality procedures of rounding and suppression. Suppression is primarily a data quality control measure for the earning indicators, which do not contain confidential information. To this effect, all indicators with rounded cohort sizes less than 15 were suppressed.

To protect the confidentiality of the population of interest, counts and amounts are rounded. Rounding may increase, decrease or cause no change to counts and amounts. Rounding can affect the results obtained from calculations. For example, when percentages are calculated from rounded data, results may be distorted as both the numerator and denominator have been rounded. The distortion can be greatest with small numbers.

To produce estimates of apprenticeship income, the disclosure control rules, as outlined on the T1 Family File web page, were used.

4. Methodology of the income indicators

Employment income data for the RAIS statistical tables (37-10-0194-01 and 37-10-0195-01) are obtained from the T1 Family File.

Employment income includes employment earnings (wages and salaries, commissions from employment, training allowances, tips and gratuities, and tax-exempted Indian employment income) and net self-employment income (net income from business, profession, farming, fishing and commissions). Net self-employment income may be positive, negative or zero.

4.1 Indicator definitions

Income cohorts are groups of individual who certify during the given calendar year. There are three income cohorts: journeypersons, individuals who completed an apprenticeship program, and trade qualifiers. For more details on the individual income cohorts, refer to section 3.2.

Median age at certification for all those who became certified in the given calendar year is available in both the longitudinal and cross-sectional tables. The median is determined by sorting values and selecting the middle value. When there is an even number of observations, the median is the average of the two middle values.

Median employment incomes (cross-sectional) are calculated at two and five years after certification.

Median employment incomes (longitudinal) are calculated at four years before certification, two years before certification, the year of certification, two years after certification and four years after certification for individuals who certified in selected trades.

The progression of median employment income is the percentage difference between the median employment income at certification and the median employment income at two and four years after certification.

4.2 Limitations of the income indicators

Income data for the RAIS tables (37-10-0194-01 and 37-10-0195-01) are obtained from the T1 Family File. These data may not necessarily reflect full-time or full-year employment, they do not account for the number of hours worked, and they do not necessarily reflect employment in the trades of interest. For more information on tax data, visit the T1 Family File.

Individuals who do not file taxes during the timeframes associated with the estimates are excluded from these income estimates. Percentages of tax-filers are provided in the RAIS tables (37-10-0194-01 and 37-10-0195-01) as important data quality indicators. The cross-sectional income table 37-10-0016-01 and the longitudinal income table 37-10-0017-01 were archived and replaced respectively by the tables 37-10-0194-01 and 37-10-0195-01. Some indicators values between both tables were not comparable, especially for cells where preliminary flags were raised.

Individuals with self-employment income are another consideration in tax data analysis. The 2011 Statistics Canada study “The financial well-being of the self-employed”Note 1 demonstrated that Canadians with only employment income are quite different from those with incorporated and non-incorporated self-employment income. Only individuals with non-incorporated self-employment income can be identified through current data holdings. Therefore, median employment incomes are presented as two measures, including and excluding those with non-incorporated self-employment incomes.

5. Geography and trades

Earning indicators are produced for all trades at the aggregated level and at the disaggregated level for some selected trades, including 25 Red Seal trades with the largest number of certifications in Canada. Estimates are available for Canada and all provinces, including the Atlantic region, and the Territories grouped together to obtain sufficient cohort sizes.

In Canada, apprenticeship programs and certifications in trades are administered by provincial and territorial jurisdictions. As a result, definitions that govern apprenticeship programs and the way data are reported to Statistics Canada can vary considerably across jurisdictions and across trades themselves. Thus, focusing on the most common Red Seal trades in Canada helps to reduce some of these administrative differences.

While some jurisdictions were able to contribute to the Canada-level results, some jurisdictional-level estimates or estimates for women may not be available because of small cohort sizes that fall below predetermined thresholds. These were specified to ensure estimates of acceptable quality and to ensure the confidentiality of the data.

Few estimates are available in the territories because of small cohort sizes. Quebec was excluded from the Canada- and provincial-level estimates on a number of occasions because of different administrative practices. For more information, see Appendix A and Appendix B of this document.
