Structural changes in Canadian employment from 1997 to 2022
Bibliographic record
Abstract
This paper uses the European Jobs Monitor (2017) 'jobs' approach to examine the structural changes in employment and wages in Canada between 1997 and 2022. Changes in employment and real wages reveals a long-term pattern of upgrading, particularly after the 2008 financial crisis. There is variation in these patterns within the 25-year period including a shift towards higher quality jobs after the financial crisis and evidence of wage polarisation between 2020 and 2022. Employment and wage trends by sector, sex and age were explored. Employment shifted away from manufacturing towards the healthcare and social assistance, professional, scientific, and technical services, and construction sectors since the late 1990s which accelerated after the global financial crisis. The wage gap and difference in employment shares between men and women has narrowed over time, despite recent widening following the pandemic. Canada's aging population has resulted in a growing share of mature workers in the labour market and in core-age workers becoming more concentrated in mid-to-high wage jobs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
