Statistics Canada published an interesting study today looking at the
urban greenness of major centres across the country. They did it by looking at satellite images of urban areas and looking at how green pixels were.
The largest cities were all less green than smaller centres, as you might expect, and all lost green space from 2001-2019. Edmonton went from 65% green in 2001 to 60% green in 2019. However, the green was stable between 2011 and 2019. The change is mostly explained by population growth, though other factors such as drought and pests, also play a factor.
Other cities, such as Vancouver, saw much larger declines.
