Making Room for Growth: Housing Intensification in Canada’s Cities, 2016-2021 is a new study that finds despite a housing shortage in many cities across the country, the number of housing units in 26.4 per cent of Canada’s urban neighbourhoods—more than one-in-four—actually declined from 2016 to 2021. What’s more, half of all neighbourhoods in Canadian cities saw the number of housing units increase by less than one per cent.
