Built-up area, Thunder Bay census metropolitan area (CMA) and census metropolitan area-ecosystem (CMA-E), 1971, 1991, 2001 and 2011

The title of this map is Built-up area, Thunder Bay census metropolitan area (CMA) and census metropolitan area-ecosystem (CMA-E), 1971, 1991, 2001 and 2011. This map has two main components—a large map zoomed into the main CMA built-up area and an inset map locating the built-up area with respect to the boundaries for the full CMA and CMA-E.

On this map, pale pink with dark pink diagonal lines represents 1971 built-up area, light pink represents 1991 built-up area, medium pink represents 2001 built-up area and dark pink is used to represent 2011 built-up area. Census metropolitan area-ecosystem boundaries are represented by a green line, census metropolitan area boundaries are represented by a black line. Some place names are included on the map. Land areas outside of the census metropolitan area-ecosystem are coloured pale yellow and areas within the United States are coloured pale grey.

In Thunder Bay, much of the expansion of built-up area from 1971 to 2001 occurred in the areas adjacent to the 1971 built-up area, particularly to the west. There was little new built-up area between 2001 and 2011.

Note: Sources for 1971 built-up area do not contain the same level of detail as the more recent years.
