{"id":847,"slug":"client-bjf-project-hard-bits","title":"B&J — what was hard (for the \"what surprised us\" section)","kind":"reference","scope":"client-case-studies","status":"current","audiences":["kevin","candid-team","client-prospect"],"topics":["regulatory-compliance","client-boucher-jones","case-study-source","engagement-scope"],"reference_body":"**[Our observation]** throughout this section.\n\n1. **The regulatory layer is intricate and Ontario-specific.** O. Reg. 217/01 vs O. Reg. 213/01 is the most-confused operational question in customer conversations. Coloured fuel under Ontario's *Fuel Tax Act*. TSSA Mobile Fueling Licence requirements. The 2025 propane tax changes. The April 2026 federal excise suspension. All of this had to be researched primary-source (not Wikipedia, not industry blog posts) before it could be written into copy.\n\n2. **The lubricants OEM crosswalk.** Petro-Canada Lubricants publishes a handbook with 269 products and 95 OEM specs across John Deere, Case IH, Massey, Volvo, Mack, Cummins, Allison, etc. Translating that into a customer-facing decision tool with named approval-status labels required parsing the handbook, reconciling sub-brands, and ingesting product images — three separate Claude Code sessions to get right.\n\n3. **The Davis & McCauley transition.** B&J recently acquired Davis & McCauley Fuels in London. The digital transition is delicate: kill the brand too fast and you lose D&M's existing search equity; keep it too long and you fragment B&J's brand. The transition page strategy (the audit's \"single most important architectural decision\") puts D&M's existing URLs through a content-driven landing page rather than a hard redirect to B&J's homepage.\n\n4. **Source-attribution density.** Every page that surfaces a tax rate, a regulatory citation, or a program status needs a tooltip and a sources footer. This is visually heavy and required design discipline to keep readable.\n\n5. **The state-machine for programs.** OSCIA intake windows open and close; iMHZEV ended; the federal carbon charge went to zero but invoices still showed it through Q1 2025; the federal excise suspension is time-bounded. Modeling \"what's currently in effect\" with stale-data behavior visible to the user was nontrivial.","rationale_body":null,"metadata":null,"links":{"outgoing":[],"incoming":[{"slug":"client-bjf-case-study-source-v1","title":"Boucher & Jones Fuels — case-study source material, v1 (parent index)","kind":"reference","scope":"client-case-studies","link_type":"relates-to"}]},"created_at":"2026-05-24T00:26:55.503Z","updated_at":"2026-05-24T00:26:55.503Z"}
