We Used AI To Measure Canada's Urban Sprawl

We Used AI To Measure Canada's Urban Sprawl

“We’re a suburban nation,” said Sasha Tsenkova, a professor of architecture, planning and landscape at the University of Calgary, who looked at our findings. In all, 1,700 square kilometres have been added to the country’s nine biggest metropolitan areas since 2001. It’s as if the country’s urban areas have increased by three-and-a-half times the size of the island of Montreal.

- And since urban sprawl (up 34 per cent) has progressed on average faster than population growth (up 26 per cent), each Canadian occupies, on average, more space, farther away from city centres. In 2001, residents of the nine largest centres occupied an average of 317 m2 of urbanized territory. In 2021, it went up by 19 m2, an area equivalent to one to two additional parking spaces for each inhabitant. --- “Urban sprawl contributes enormously to greenhouse gas emissions,” said Tsenkova. “It has an economic, environmental and social cost.” Instead of building new neighbourhoods, we should intensify those that already exist and add services and shops within walking distance, according to experts

Vancouver's numbers don't seem right - did they annex some new, previously developed areas in that time? There is simply no way Vancouver decreased in density since 2000.

It's by urban area, not city proper.

Still doesn't seem right. The weighted density of Vancouver's urban area is higher than it was in 1950, and its ability to sprawl has been significantly restricted in the past 2 decades.
