Where the increase comes from

Division over time

Division

Annual price change, non-residential buildings. Select any row in the table to chart it.

Weight is the division's share of the building type's price in that place. Points = weight × annual change, the amount each division adds to the overall rate. Structural and architectural divisions are priced from a contractor survey; mechanical and electrical from administrative data.

Test a budget against the index

Apply the observed change for your place, building type and trade to a scope of work. It looks back, so treat it as a test of a budget and get current quotes before you commit.

How to read these figures

What the index measures

The index tracks quarterly changes in the price contractors charge to construct six representative non-residential buildings: an office, a warehouse, a shopping centre, a factory, a school and a bus depot. The price includes materials, labour, equipment, overhead and profit. It excludes land, design, development charges, real estate fees and value-added taxes.

Statistics Canada groups the factory and bus depot as industrial, and the office, warehouse and shopping centre as commercial. Index levels show change since 2023 and say nothing about cost per square foot between cities.

What counts as London

How LDCA made its calculations

Division points. Each division's weight in the selected index, multiplied by its annual price change. Points sum close to the published rate; the small difference arises because weights are updated once a year.

Mix and price. London's gap over Ontario is split across the six building types. The mix part is half the difference in weights times the sum of the two rates. The price part is half the difference in rates times the sum of the two weights.

Budget check. Value × observed change for the place, building type and trade selected. It is a look back, not a forecast.

Limits. Weights change once a year, so a split across four quarters is an approximation. Statistics Canada publishes no response counts or margins of error by city.
