Mortgage-backed securities in Canada: the size of the market and prospects for the future
Bibliographic record
Abstract
Mortgage-backed securities (MBS) were introduced into the Canadian financial system in 1987. This paper describes their development and history, and compares these with the situation in other countries, through a brief review of mortgage securitisation in various parts of the world (the UK, Australia and Japan). The primary uses of MBS in Canada and positive aspects of securitisation are explored, both as they have been experienced since the inception of MBS in the late 1980s and as they relate to the basic structure of the mortgage finance system in place before MBS were introduced. The paper also contrasts the MBS markets in the USA and Canada. The proportion of national mortgage debt that is packaged into MBS in both countries is examined, and the paper discusses reasons for the significantly smaller proportion of debt in Canadian MBS versus the numbers for the USA. Future prospects for growth in the Canadian MBS market are explored. Copyright © 2005 Henry Stewart Publications

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.
