Direct answer

For early retail construction cost planning in Montréal, the World Bank ICP reports a 2021 Canada construction price-level index of 217.0, with the world equal to 100. This is a national comparison—not a Montréal CAD/m² rate or tender estimate—so replace it with current local evidence before budgeting or procurement. The observation covers construction across Canada in 2021; it does not measure a Montréal market basket or current retail tenders. GeoNames 6077243 records the locality at 45.5088, -73.5878, with snapshot population 1,762,949. That ranks Montréal 2 of 50 listed places, while Rosemont–La Petite-Patrie is the nearest listed peer at about 3 km. Use these facts only to plan the comparable search. Obtain current local rates on a consistent area basis, then reconcile scope, taxes, fees, contingency and escalation. Retain the source, base date and reviewer when local evidence replaces the screening ratio.

What does the 217.0 construction index mean?

The World Bank ICP 2021 construction PLI for Canada is 217.0, compared with a world benchmark of 100. It is a national spatial price comparison assembled for the 2021 reference year. It does not say that retail work in Montréal costs 2.170 times a current world rate.

Which Montréal inputs are known?

The reproducible locality point is 45.5088, -73.5878 (GeoNames 6077243). Its snapshot population is 1,762,949, ranked 2 of 50 listed places; GeoNames classifies it as a second-order administrative seat in administrative area 10. These facts shape the local comparable search, not the price.

What must a project estimate add?

For a Montréal retail project, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works. Use a consistent gross-floor-area basis and record the following before reliance.

Estimate field	Screening record	Project requirement
National context	ICP 2021 PLI 217.0	Retain only as dated cross-country context
Local CAD/m² rate	Not supplied	Current comparable with named source and base date
Area and scope	Gross floor area; scope unresolved	Measurement standard, specification and procurement route
Additions	Not supplied	Taxes, fees, site work, contingency and escalation
Review	Automated source and arithmetic QA	Qualified local cost review

Price-level normalization worksheet

For a validated reference rate R from a country with construction PLI P, the transparent screening calculation is R × (217.0 ÷ P). At P = 100 the dimensionless ratio is 2.170; no world cost rate is asserted. Keep the reference rate's currency, base date, area basis and scope attached.

Input	Recorded value	Release condition
Target national PLI	217.0 (World = 100, 2021)	Screening context only
Reference construction PLI P	User-supplied from the same ICP classification/year	Must match reference rate country
Validated reference rate R	User-supplied	Named source, currency, date, area and scope
Local Montréal adjustment	Not asserted	Replace with current local comparable evidence
Result status	Screening normalization	Not a budget, quote or tender estimate

Frequently asked questions

Does the 217.0 index give a retail cost per m² for Montréal?

No. 217.0 is the World Bank ICP 2021 national construction price-level index for Canada, with the world equal to 100. It is a cross-country screening statistic, not a Montréal CAD/m² rate, escalation index, quote or tender estimate.

How should a Montréal retail estimate replace this screening benchmark?

Collect current Montréal comparables on a consistent gross-floor-area basis, reconcile shell condition, tenant fit-out, servicing, trading constraints and landlord works, and state base date, currency, taxes, fees, site work, contingency and escalation. A qualified local cost professional should review the resulting project estimate.
