Open Nshipyard Canada · Housing cost drivers
What drove Toronto's 4.6x construction-cost rise?
We split Toronto's new-house price index into house-only and land-only, then matched the house-only series against union wages, materials prices, and building prices from 1981 to 2026. Union construction wages rose 4.55x, tracking the 4.64x construction-cost rise almost exactly. Materials rose less: fabricated metal 4.01x, concrete 3.66x, lumber 3.11x.
4.64x
rise in the house-only (construction cost) component of Toronto's New Housing Price Index, 1981 to 2026
4.55x
rise in Toronto union construction wages including supplements, 1981 to 2026; the closest tracker of the 4.64x construction-cost rise
4.01x
rise in fabricated metal products, the fastest-rising major material nationally, still below construction costs
3 gaps
drivers with no open StatCan series: development charges, code-compliance costs, Toronto-residential productivity
The decomposition
Union wages rose 4.55x since 1981, almost matching the 4.64x rise in construction costs. Materials rose less.
All series rebased to 1981=100. Toronto union construction wages (including supplements) move with the house-only construction-cost index across the full 45 years, ending at 4.55x against 4.64x. National materials prices sit below both: fabricated metal 4.01x, concrete 3.66x, lumber 3.11x with a sharp 2021-2022 spike, total industrial prices 3.12x.
…
IPPI series are national factory-gate producer prices, shown as upstream input-price shocks, not Toronto builder costs. Lumber January values are volatile; the 2021-2022 spike is flagged in the data file.
Shorter windows, shown separately
These series cannot start in 1981, so they are shown on their own base and never stretched. StatCan's residential building-type detail begins in 2017; detailed iron and steel products begin in 2010.
Toronto residential building prices, 2017=100
Single-detached 2.33x and townhouse 2.32x, 2017 to 2026, with the house-only index rebased to 2017=100 for comparison.
…
Iron and steel products, 2010=100, national
Basic and semi-finished iron or steel products rose 1.54x from 2010 to 2026, below total industrial prices at 1.64x over the same window.

Driver ranking
Five drivers, ranked by evidence.
Each driver carries one sourced number. Where the evidence comes from industry surveys instead of a Statistics Canada series, the panel says so plainly.
Productivity stagnation
Residential construction output per hour in 2024 sat about 8% below its 2000 level, falling roughly 0.4% per year; CMHC estimates lost productivity added $6-8B to housing construction costs, up to 20% of the price rise.
No open series: CSLS and CMHC analytical reports, not a downloadable Toronto-residential series.
Labour and wage costs
Toronto union construction wages including supplements rose 4.55x from 1981 to 2026, tracking the 4.64x construction-cost rise almost exactly; the national construction job vacancy rate peaked at 8.3% in April 2022.
Open series: StatCan 18-10-0140-01, Toronto CMA. Union wage-scale proxy, not all-worker earnings.
Materials
Fabricated metal products rose 4.01x and ready-mix concrete 3.66x nationally since 1981, both below the 4.64x construction-cost rise; softwood lumber rose 3.11x with a sharp 2021-2022 spike that later receded.
Open series: StatCan 18-10-0266-01, national factory-gate prices, not builder acquisition cost.
Codes and approval delays
Toronto's development approval backlog grew from 21 months in 2020 to a 32-month weighted average in 2022; CHBA estimates 2025 code changes could add over $100,000 to a typical 2,500 sq ft home.
No open series: CHBA and Altus Group surveys, not a government statistical program.
Development charges and fees
Development taxes, fees and levies rose about 700% over two decades, averaging about $82,600 per low-rise unit in 2024, up $27,500 since 2022.
No open series: CHBA municipal benchmarking surveys for 2022 and 2024.
What this means
Three levers the data points to.
Speed up approvals.
Toronto's approval backlog reached a 32-month weighted average in 2022; every month of delay adds carrying costs that compound into the final price.
Rebuild productivity.
Output per hour fell about 0.4% per year from 2000 to 2024; factory-built and modular methods attack the largest structural driver directly.
Publish the fees.
No open series tracks development charges over time; a public longitudinal series would let every municipality's fee burden be compared and debated.
Sources
Every number has a table.
All index series come from Statistics Canada -01 level tables, extracted 2026-10-10 and rebased as documented in the data file. Driver research came from three Keenable SELECT reports run 2026-10-10.

What open data cannot answer
- Development charges and municipal fees: no StatCan longitudinal series exists for any period; the 700% figure comes from CHBA benchmarking surveys.
- Building-code compliance costs: no open series; the $100,000-per-home estimate is a CHBA industry figure.
- Toronto-residential productivity 1981-2026: no downloadable series; the cited facts come from CSLS and CMHC analytical reports.
- Contractor profit margins: baked into the BCPI selling-price concept, never published separately.
Driver research: three Keenable SELECT reports (25, 39, and 55 evidence rows) run 2026-10-10, covering cost drivers, the StatCan table catalogue, and normalization fixes.
