In Toronto’s Bridle Path, Bayview Village, and Willowdale neighbourhoods, the average resident can expect to live past 84 years of age—higher than even Japan’s world-leading life expectancy. Meanwhile, in less affluent parts of the city, such as Rexdale, Oakridge, and Moss Park, death comes more than a decade earlier—on par with countries like Tunisia and Nicaragua.

Those stark numbers, published here for the first time, are the results of a monthslong collaboration between The Local and researchers at MAP Centre for Urban Health Solutions at St. Michael’s Hospital. The project uses the latest available data from the 2021 census and 2020 and 2021 provincial death records to examine life expectancy at birth in all 158 neighbourhoods of Toronto—that is, how long a child born in a particular corner of the city would live if current patterns of mortality remain unchanged.
