The History of Occupational Therapy Assistants in Canada: A Comparison with the United States
Bibliographic record
Abstract
In the middle of the twentieth century, the role of occupational therapy assistant was introduced in North America. Although the role, utilization and training of assistant personnel have raised much controversy and debate within the profession, Canada and the United States have taken very different paths in terms of dealing with these issues. This paper focuses on the history of occupational therapy assistants in Canada, using the experience in the United States for comparison purposes. The occupational therapy literature and official documents of the professional associations are used to present a chronology of major historical events in both countries. Similarities and differences emerge in relation to historical roots; training model and standards of education; certification, regulation, and standards of practice; career laddering and career mobility; and professional affiliation. The paper concludes with a summary of issues which require further exploration, debate and resolution if the profession is to move forward in Canada.

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.
