Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Targeted industrial and sectoral subsidies (renewable energy, chip manufacturing, agriculture, green hydrogen, etc).
Canadian countermeasure tariffs in response to US tariffs imposed under the Trump administration (25% on Canadian goods and 10% on Canadian energy/potash, effective 4 March 2025 under IEEPA, subsequently modified and partially delayed for CUSMA-compliant goods). First Canadian tranche: 25% tariffs on C$30B of US imports effective 4 March 2025 covering agricultural products, consumer goods, steel/aluminium derivatives. Announced second tranche on a further ~C$125B of US imports to take effect in stages if US tariffs persisted. Sectoral escalation included 25% tariffs on US-made vehicles not CUSMA-compliant in response to US auto tariffs (April 2025), plus matching steel and aluminium countermeasures. Tariff revenue earmarked in announcements for worker and sectoral support programmes. Transition of leadership from Trudeau to Carney (14 March 2025) occurred during escalation; Carney government retained and extended the measures.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
