The Pan-Canadian Carbon Tax: A Constitutional Perspective
Bibliographic record
Abstract
The use of tax policy to address environmental destruction is entering a new phase in Canadian history with the adoption of a Pan-Canadian Framework on Clean Growth and Climate Change, which features a federal carbon tax regime. This Framework is designed as a backstop to existing sub-national regimes, effectively according primary taxing rights to the provinces and territories and residual rights to the federal government. This design creates a floor for carbon taxation across the country. An important question is whether disagreement is likely to arise among the jurisdictions themselves or by those subject to the regimes. If so, Canada’s constitution will come into play as the arbiter of jurisdictional authority and conflict. This chapter accordingly analyzes the Pan-Canadian Framework against the variable landscape of environmental taxes in Canada to date, and considers the possibility for either harmonization or discord going forward.

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.
