Where the prices we show come from

This site shows building material prices from several sources, and each source is not equally reliable — prices collected by government agencies and prices typed in by stores shouldn't be mistaken for the same thing. This page says plainly what we have now, how much, and when it was last updated. Every figure is read from the live database when you open this page

Retail prices from online stores

Source: collected from store web pages that publish prices publicly

About 607,842price records

The prices online stores actually sell at, used to compare what each store charges for the same item

ReliabilityReal retail prices, but **not broken down by province**, and some include delivery while others don't, so they can't be used directly for a BOQ

What we don't have yet — the government's standard labor rate schedule and full construction reference prices haven't been imported yet, so labor costs in quotations currently come from what you enter, not from a government schedule

Every figure the system calculates always says which province and month it comes from, and if there's no data for that province, we say we used the regional or national average instead We never quietly show another province's prices
