BILD remains in the federation, but the underlying friction is structural — **BILD is the largest single local in OHBA's membership** (>1,000 of ~4,000 OHBA member companies), and the relationship between the largest local and the provincial body has been a recurring stress point.\n\n**Source:** Ontario Construction Report, June 2023.\n**Confidence:** Reported.\n\n## Why this matters for Candid use\n\nFor **GTA-focused builder/renovator clients**, the recommended footer logo stack should lead with **BILD**, then OHBA, then CHBA — not the reverse. BILD is the dominant brand in the GTA market and the one with the most active local-level events, awards, and advocacy presence.\n\nIf BILD ever **formally leaves OHBA**, the recommendation for GTA clients **flips** — lead with BILD branding, drop OHBA logos entirely. As of May 2026 BILD is still an OHBA member, but the trajectory is worth watching.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"renomark-origin-bild-2001-transfer-chba-2024","title":"RenoMark origin: launched 2001 by BILD (then GTHBA); trademark transferred from BILD-GTA to CHBA in June 2024","kind":"reference","scope":"business","link_type":"relates-to"}],"incoming":[{"slug":"research-brief-canadian-hba-stack","title":"Research brief: The Canadian HBA stack — CHBA / OHBA / BILD / WRHBA federated three-tier model, with marketing implications for Ontario builders and renovators (May 24, 2026)","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-24T16:32:33.775Z","updated_at":"2026-05-24T16:32:33.775Z"}
