Abstract
The Canadian Competition Bureau has recently offered new draft guidelines on the abuse of dominance that, in the area of joint dominance, depart from the existing guidelines in two ways: first, the bureau no longer considers as a potential abuse of joint dominance the adoption of practices that facilitate supra-competitive pricing in an oligopoly; second, while in the past some form of explicit coordination was required for an assessment of joint dominance, the bureau now considers parallel abusive conduct by jointly dominant firms as potentially infringing the abuse provisions. The first change, which we attribute to case law rather than to the bureau, is undesirable. The adoption of facilitating practices can lessen competition, and is practically remediable. Facilitating practices should be considered potential abuses of joint dominance. On the other hand, the second change is sensible: oligopolists may profitably adopt exclusionary practices in parallel without coordination. Parallel exclusionary practices may lessen competition even when no single firm has a dominant market share, and this problem is amenable to a practical remedy. The bureau's new approach is welcome on this front.

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 it
