Poly B across Canada, city by city
Poly B was a national product, but its footprint varies enormously by city depending on when each one grew. These profiles cover Canada’s 119 largest municipalities using Statistics Canada’s 2021 Census build periods.
How to read these numbers
Each city shows the share of its occupied homes built during the 1978 to 1998 Poly B installation window, weighted the same way our address checker scores any address. City averages hide the street-level story: every city below contains subdivisions that are nearly all Poly B era and districts that entirely predate it. For Calgary, Edmonton and Kelowna, the neighbourhood profiles go a level deeper.
