Split February 1 2021 ([[hcra-launched-feb-1-2021-replaces-tarion-regulator]]). **Archive, not socialize**; function as ground-truth layer.\n2. **Trade associations.** BILD GTA 1,000+ member companies ([[bild-gta-2008-merger-1000-members-2023-ohba-tension]]); cascades into OHBA and CHBA. Membership directories are how members find each other.\n3. **Supplier and distributor counters.** Lumber yards, plumbing supply, electrical wholesalers. **Weak-tie infrastructure** — bridge contractors who otherwise would never meet. Information about who pays slowly, who is over-leveraged, who is a difficult site to be subcontracted to circulates at velocity no formal channel matches. Under-studied academically. (Anecdotal / Industry-consensus.)\n4. **Industry events.** BILD events incl. GTA RenoMark Awards, OHBA Awards of Distinction, Ontario Building and Renovation Forum, Construct Canada; consumer-facing Toronto/National Home Shows. **Dual function**: weak-tie generators + reputation-witnessing infrastructure (see [[events-as-trust-witnessing-not-lead-generation-infrastructure]]).\n5. **Digital channels.** Trade-specific Facebook groups, Reddit (r/Contractor, r/Construction, r/HomeImprovement), WhatsApp/Signal cohort chats coordinated through HBAs or peer-coaching cohorts. Functionally Burt-style brokerage infrastructure with weaker trust-per-tie. (Directional; rapidly evolving — revisit within 12 months.)\n\n**Confidence:** Synthesis. Layer 1-2 verified from organization-published data; layer 3-4 industry-consensus; layer 5 directional.\n\n**For Candid:** Network membership is layer-specific. Being known at the lumber yard does nothing for OHBA reputation. Reputation accrues in the layer where it accrues; cross-layer transfer is slow.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"research-brief-trust-networks-in-group-reputation-may-2026","title":"Research brief: trust, referral networks, and in-group reputation in Ontario's trades economy (May 2026 — Foundation Brief #3)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"burt-structural-holes-1992-2004-broker-advantage","title":"Burt 1992 (Structural Holes) / 2004 (AJS) — brokers spanning holes between groups capture information-arbitrage advantage","kind":"reference","scope":"business","link_type":"relates-to"}],"incoming":[{"slug":"events-as-trust-witnessing-not-lead-generation-infrastructure","title":"Events as trust-witnessing infrastructure — HBA dinners / awards nights are public ratification venues; measure share-of-voice, not leads-attributed","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"rule-network-membership-precedes-referral-program-design","title":"R1 — Network membership precedes referral-program design; \"we have a referral program\" is not a strategy until \"we are in the network\" is true","kind":"rule","scope":"business","link_type":"depends-on"}]},"created_at":"2026-05-25T13:34:11.128Z","updated_at":"2026-05-25T13:34:11.128Z"}
