OHBA: formed 1962 with 10 locals, today "over 4,000 member companies through 28 local chapter associations" (older materials cite 27/29/31), CEO Scott Andison
Claim: OHBA was formed in 1962 with 10 locals. Today represents "over 4,000 member companies in the home building, land development, professional renovation and professional services sectors through 28 local chapter associations across the province" (OHBA's authoritative September 29, 2025 brand-relaunch release).

Local-association count VARIES across sources — important editorial caveat
| Source | Local count |
|---|---|
| OHBA September 29, 2025 brand-relaunch boilerplate | 28 |
| Current ohba.ca "Who We Are" page | 29 |
| WRHBA's OHBA page (wrhba.com/pages/ohba) | 31 |
| One 2024 OHBA release | 27 |
The variance reflects mergers (e.g., Hamilton-Halton becoming West End HBA), the BILD/OHBA tension (see BILD GTA: formed 2008 from GTHBA + UDI/Ontario merger, "more than 1,000 member companies," threatened in 2023 to leave OHBA over a "one-voice" operating model dispute), and dormant chapters.
For published copy: use "28 local chapter associations" (the authoritative September 2025 boilerplate) and footnote the variance.
Economic-impact framings (also vary)
OHBA's stated economic impact:
- "the residential construction industry contributes over $66.6 billion to Ontario's economy" (2024 release)
- "over $76 billion" (2022–2023 releases)
- "more than 500,000 people" employed
- "more than 700,000 homes built in more than 500 Ontario communities" since 2007

OHBA stakeholder role with HCRA and Tarion
OHBA has a formal stakeholder relationship with both HCRA and Tarion. OHBA's website includes a dedicated "Tarion & HCRA" page describing both regulators' roles. OHBA filed a formal response to HCRA's 2025 fee consultation (see OHBA major advocacy 2022–2025: Bill 23 (More Homes Built Faster), municipal development charges, landmark 2025 AMO/OHBA joint DC modernization, HCRA fee increase pushback) and represents builders on multiple Tarion stakeholder consultations (notably the Addendum revamp).
