The map is zoomed  in to the Ottawa Census tracts. The dark colours represent the areas of highest median income in 2015, the most recent year for which Statistics Canada made income data available.

The city of Ottawa municipal boundaries are layered on top of the census tracts to provide a better sense of where the areas of interest are located.

Clicking inside the census tract boundaries produces a pop-up box with the median household income for 2005 and 2015, along with the percent change.

There are a few blank census tracts, which Statistics Canada says do not contain any data.

If you want to see other locations, simply zoom out, and then zoom in to the urban centre such as Vancouver, Toronto or Halifax.
