- research-notes Gaps: MLS-data inside-the-box brief (June 2026) — public-data register not located; counsel items
- reference Caveats: MLS-data inside-the-box brief (June 2026) — untested clauses, self-reported metrics, contested copyright status
- reference OPC PIPEDA Case #2009-004 — combining *publicly available* directory info with geo-demographic stats did NOT create new personal info requiring consent; **by analogy, sufficiently aggregated/de-identified MLS market stats likely fall outside PIPEDA consent (DS for the threshold)**
- reference OPC PIPEDA Case #2005-303 (and BCREA #409) — using OTHER agents' MLS sales records in a "top 5 sellers" ad without consent breached Principle 4.3
- reference OPC Case Summary #2009-002 — sold price + address is personal information; pulling from MLS does NOT qualify for "publicly available" consent exemption (decisive against MLS-sourced republication)
- reference Even where MLS prohibits *displaying* sold/expired/withdrawn/pending data, broker-selected comparables for a CMA are permitted ("both on a VOW and in the office")
- reference Durable member edge has shifted from headline sold price to the deeper structured layer (relisting chains, sub-market absorption, list-vs-sold spreads, off-market, ListTrac analytics)
- reference Consumer portals commoditised the "just-sold" edge — practitioner consensus; portals cannot capture local nuances, off-market activity, or hold-offer strategies
- reference HouseSigma — self-reported "2M+ registered users / 5M+ monthly visits" + "1.9M Active Users / $500M+ Yearly $ Volume"; internally inconsistent across pages — flag
- reference Cumulative DOM now displayed in Toronto / Hamilton / Niagara MLSs — eroding the reset tactic
- reference Cancel-and-relist resets DOM to zero — Pasalis-adjacent practitioner (Globe & Mail); condo relistings hit 163pct of sales in mid-October in the 416; GTA condo months-of-inventory 3.1 in September
- reference Months of inventory (absorption) = active listings ÷ monthly sales; 0-4 seller / 4-6 balanced / 6+ buyer (Ontario practitioner framing)
- reference Typical agent uses a sliver of the 1,745-field MLS dataset — active search, a handful of comps for a CMA, posting their own listing
- reference CREA — owns MLS®/REALTOR®/Multiple Listing Service® registered trademarks; licences member boards; runs REALTOR.ca + DDF; sets national By-Laws, Rules, REALTOR® Code, Three Pillars of the MLS® Mark
- reference PropTx Innovations Inc. — TRREB's wholly-owned for-profit/taxable MLS subsidiary; REALM front-end merges land-registry and MLS data; ~70,000 members
- reference Back-office feed — deepest tier, powers CRM / listing / document management; must not be public; requires broker consent
- reference VOW (Virtual Office Website) — password-protected, requires established broker-consumer relationship, carries the deeper historical/sold/off-market layer
- reference IDX (Internet Data Exchange) — NAR-governed reciprocity *policy* (not a feed), active listings + pending/sold per local option, public display no login
- reference CREA Data Distribution Facility (DDF®) — created 2012, opt-in via REALTOR Link®; multiple channels; feeds are consumer-grade (REALTOR.ca-level), NOT the deep layer
- reference RESO Web API — REST/JSON on OData v4, OAuth, calls MLS directly (no local DB duplication); NAR requires REALTOR-association MLSs to provide production-level Web API access
- reference TRREB monthly Market Watch — includes "Month's Inventory" (absorption)
- reference TRREB / PropTx REALM — bundles ListTrac listing analytics, HoodQ 450+ GTA neighbourhood guides, SkySlope forms
- reference ITSO Matrix — "more than 500 fields across property types, plus CMA tools, land registry data, neighbourhood insights, Authentisign, AnswerLink, and live market statistics"
- reference RESO StandardStatus lookups + HistoryTransactional resource — the schema that models the historical layer
- reference NAR VOW policy — minimum of 3 years of sold data required in IDX/VOW feeds
- reference PropTx / MPAC appraiser product — 3-year residential / 5-year commercial PropTx MLS sales history with full listing details and photos
- reference Competition Bureau (Canada 2014) — TRREB MLS "much more detailed than… REALTOR.ca," holds previous prices, comparables, time-on-market
- reference RESO DD 2.0 — Property resource is 652 fields, organised into 13 groups
- reference RESO Data Dictionary 2.0 — 41 resources / 1,745 fields / 3,683 lookups (ratified Oct 23 2023; effective April 15 2024)
- research-notes Research notes (capture-layer): inside the MLS box — what an Ontario member agent's account exposes, what goes unused, and what they're licensed to do with it (June 2026)
