Abstract
This article is dedicated to the principles of forming a commercial bank’s mortgage loan portfolio, drawing on Canadian practices and comparing them with international approaches. The relevance of the topic is driven by the high share of mortgage assets on bank balance sheets and the increased debt burden of households. The novelty is formulated by linking regulatory requirements, insurance mechanisms, diversification, and asset-liability matching into a unified risk management framework. The paper describes underwriting standards, the logic of mandatory and portfolio insurance, diversification strategies that account for climate factors, and the impact of securitization on liquidity and capital. The study examines regulatory documents, industry reports, and academic publications on credit risk and stress testing. Particular attention is given to the consequences of short-term interest rate fixation in Canada and the impact of term renewals on portfolio stability. The work aims to develop a set of principles for maintaining an acceptable risk-return trade-off. To achieve this objective, comparative analysis, synthesis, regulatory analysis, and elements of scenario-based stress testing were employed. The conclusion describes the practical applicability of the findings for banks and supervisory authorities. The article will be useful for risk managers, regulators, and researchers of banking stability.

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.
