Abstract
This paper explores the means by which tax authorities worldwide seek to strengthen their tax treaties, through safeguards of varying nature and scope, in order to identify and prevent what they consider to be abuse of such treaties. These means of challenge may be grouped under two headings: purposive approaches to treaty interpretation, particularly with respect to the terms 'person', 'resident' and 'beneficial ownership'; and broader responses to unacceptable tax avoidance, specifically reliance on treaty anti-abuse principles and domestic anti-avoidance rules. The Canadian response is evinced by two recent cases in which the government unsuccessfully challenged 'treaty shopping' arrangements, MIL (Investments) SA v Canada and Prevost Car Inc v Canada. Building on the existing literature regarding tax treaty shopping and other forms of tax treaty abuse, this work seeks not only to describe and explain the responses to treaty abuse but to make a critical inquiry into the essence of such abuse, particularly as it appears to be viewed by the Canadian revenue authorities. It is argued that the Canadian response to tax treaty abuse is inadequate, largely because it conflates multiple approaches and fails to address a key concern: the existence or lack of genuine economic establishment in the treaty state. The paper concludes with some suggestions for fashioning a more coherent and intellectually honest response to tax treaty abuse.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
