Montreal Population Density

People per square kilometre on every city block of the island, from the 2021 census. Switch to census tracts to compare with 2016.

• Blocks are the census’s smallest areas, usually a single city block. Blocks with no residents (parks, industry, rail yards) are grey. Lines are borough and town limits.
• Tracts are groups of blocks with about 2,500–8,000 people, counted on the same boundaries in 2016 and 2021.
