Sanitation, Sanity, and (Moral) Suitability: The History of the Medical Inadmissibility of Immigrants into Canada
Bibliographic record
Abstract
Study of the history of medical inadmissibility and deportation of Canadian immigrants uncovers three important themes as criteria for immigration selection and control: sanitation, sanity, and moral suitability. As the understanding of human health changed with history, so too did the basis for exclusion and deportation of Canadian immigrants for medical purposes. Immigration policy mirrored then current notions of health and disease, growing in complexity as immigration policy increased its selectivity contemporaneous to increasing immigration rates. Immigration control developed from simple quarantine measures to prevent the transmission of infectious diseases from other continents, to physical and mental health inspections to prevent the propagation of hereditary dysfunction, to selection of morally fit immigrants resembling Canadian values for easy assimilation into society. Physical, mental, and moral health were key criteria in the first century of Canadian immigration policy, highlighting Canada’s history of anti-immigrant sentiment through the medicalization of specific ethnic groups.

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.
