The OHC platform is an open, modular set of layers that work together — and work independently. Adopt one layer or all five.
A short, looping walk-through of how parcel data, zoning, infrastructure, designs, and pro forma logic compose into a single delivery decision.

Looping · muted
OHC operates as a public-interest stack. Each layer is open, interoperable, and designed to be adopted by any jurisdiction, Nation, or developer in Canada.
A national, openly licensed dataset of parcels, zoning, infrastructure capacity, and program eligibility — harmonized across jurisdictions.
A curated catalogue of code-ready typologies — from laneway homes and infill to mid-rise — with permit-ready drawings and manufacturing specs.
Zoning, building, and program rules encoded as queryable logic — so any parcel can be tested against any rule, instantly and verifiably.
Models and copilots that compose the layers above into useful answers — feasibility, scenario comparison, design fit, and approvals readiness.
A single, transparent pipeline from raw geography to a deliverable, financeable housing project. Every step is open, auditable, and reusable across jurisdictions.

BuildBlox is the AI/software layer that applies OHC’s data, standardized designs, and rules-as-code to specific sites and programs. It turns the commons into operational answers — for governments evaluating supply, for developers running pro formas, and for Nations planning long-term housing.

DASH is a BC Housing program — delivered with Metro Vancouver Housing and funded by BC Housing, CMHC, and the Housing Growth Innovation Lab — that gives affordable housing builders ready-to-use digital design tools, permit-friendly blueprints, and a coordinated prefab supply chain. Open Housing Canada operates upstream: connecting builders to the data, bylaws, and design adapters the DASH toolset depends on, with BuildBlox as the application layer.
BuildBlox · the application layer
See all →BuildBlox is OHC’s AI/software layer. It applies open data, digital bylaws, standardized designs, and financial logic to a real parcel and a real project — covering site assessment, prefab planning, and manufacturer matching in one stack.
Parcel-level suitability against zoning, bylaws, and infrastructure capacity — and instant generation of permit-friendly typology fits.
Adapts the standardized design library against Canadian prefabricated component catalogues, sized to the site envelope.
Connects affordable housing builders with offsite manufacturing capacity nationally — beyond DASH's BC pilot regions.
Blueprint library
A growing digital library of permit-friendly multi-family typologies — usable across all BC climate and seismic zones — that affordable housing builders can adapt rather than design from scratch.
Where OHC fits
OHC is not a DASH operator. We supply the upstream commons that lets the DASH toolset run anywhere a Canadian builder works — parcel data, machine-readable bylaws, and design adapters across programs.
