Housing Cost Transparency Act

Summary#

Bill C-287 changes the National Research Council Act to make housing cost impacts more visible when Canada’s national model codes are updated. It requires the National Research Council (NRC) to publish plain-language cost and impact summaries for code change proposals that could affect housing. It also sets transparency rules for who is involved in proposals and creates a public registry. The goal appears to be clearer, easier-to-find information about how code changes may affect housing costs, timelines, and complexity.

Key changes:

• NRC must publish standardized “housing cost and impact summaries” for each material housing-related model code proposal at the start of public review.
• Summaries must explain the proposal’s intent, practical effect, estimated costs for a typical house or other common dwellings, expected benefits and drawbacks, who pays, and key uncertainties. Where possible, detailed cost ranges and assumptions are required.
• If detailed numbers are not possible, NRC must give the best qualitative (descriptive) assessment and explain why numbers are not practicable.
• NRC must publish the list of relevant governance bodies and committees for each proposal, including members’ names, roles, and affiliations, and a contact for technical and process questions.
• NRC must keep a public online registry with each proposal, its status, milestones, responsible committee, and dates; plus an edition-level estimate of the combined net impact for each new code edition and an annual summary of activities and recurring issues.
• The Act confirms NRC’s role in supporting and publishing national model codes and clarifies that provinces, territories, and municipalities keep sole authority over adoption, permitting, inspections, enforcement, zoning, and related matters. Failure by NRC to publish does not invalidate any code or government action.

What it means for you#

• Homebuilders, developers, and contractors

  • You would get standardized estimates of how proposed code changes could affect upfront costs, operating costs or savings, project timing, and compliance complexity.
  • You could see who advanced a proposal and who is on the relevant committees, with a clear contact during public review.
  • A public registry would let you track proposal status and view edition-level net impact estimates.

• Homebuyers and renters

  • You could access plain-language summaries that explain how proposed code changes might affect the cost of building typical homes or apartments.
  • This is an information change only. It does not by itself change prices, permitting, or enforcement.

• Provinces, territories, and municipalities

  • Your authority over code adoption and enforcement is unchanged.
  • You could use NRC’s estimates and summaries to inform decisions, but you are not required to act on them.

• Code committee members and proposal sponsors

  • Your name, role, and affiliation related to a proposal would be published.
  • Governance information for relevant bodies and committees would be public.

• Public, researchers, and advocates

  • You would have a central, bilingual, accessible registry of housing-related code proposals, their impacts, and annual and edition-level summaries.

• National Research Council

  • NRC would take on new duties to prepare, maintain, and publish cost/impact summaries, governance details, and a public registry, all in both official languages and in accessible formats.

Expenses#

The bill would likely increase NRC’s administrative and analysis costs; no official cost estimate is provided in the supplied material.

• Possible new work includes preparing cost/impact analyses, translating and formatting content for accessibility, and building and maintaining an online registry.
• NRC may need staff time or contractors (analysts, economists, technical writers) to produce estimates, document assumptions, and update materials.
• Collecting and verifying committee membership and affiliation information, and managing public contacts, could add ongoing workload.
• Proposal sponsors and committee members may face minor compliance effort to supply accurate names, roles, and affiliations.

Proponents' View#

• The bill appears intended to improve transparency around code changes that affect housing costs and project timelines.
• Standardized, plain-language summaries could help the public and industry take part in public reviews with better information.
• Publishing detailed cost ranges, assumptions, and uncertainties could make trade-offs clearer and decisions more evidence-based.
• Edition-level “net impact” estimates could show the cumulative effect of changes on a typical home, aiding affordability discussions.
• Listing committee memberships and affiliations could reduce perceived conflicts of interest and improve trust in the process.

Opponents' View#

• One concern is added workload for NRC, which could slow parts of the code development or review process.
• Producing reliable, detailed cost estimates may be difficult; results could depend heavily on assumptions, leading to disputes or confusion.
• Emphasis on upfront costs could, in practice, discourage proposals with long-term benefits (for example, safety or energy savings), even though benefits must be noted.
• Publishing names and affiliations might raise privacy concerns or deter some volunteers or experts from participating.
• The bill includes no penalty if NRC fails to publish on time; codes remain valid, which may limit incentives to fully comply.
• The term “material housing-related” leaves room for judgment about which proposals require summaries; borderline cases could create inconsistency.
