Jens von Bergmann who runs the Mountain Doodles blog has built some interesting visualizations over the years with the use of census data. The latest creation from von Bergmann is an interactive map of the changing population density in the Metro Vancouver Regional District from 1971 to 2016.
The following are samples looking at Langley City from 1991, 2001, and 2016. The population density is scaled the same, so it is an apples-to-apples comparison.

Beside population density, I found it interesting to see the growth of the single-family neighbourhoods south of the Nicomekl River. Starting with Eagle Heights and along 203rd, then filling-in moving west to east from 1981 to 1996. Another thing I saw was the decrease in population density from 1996 to 2016 in neighbourhoods south of the Nicomekl River due to decreasing household sizes.
From a technical explanation of the interactive map, please read the post Census Custom Timelines.
