Highlights of the new 2019–2046 projections for the reference scenario:
Ontario’s population is projected to increase by 31.5 per cent, or almost 4.6 million, over the next 27 years, from an estimated 14.6 million on July 1, 2019 to almost 19.2 million by July 1, 2046.
In the short-term, the growth of Ontario’s population is projected to be affected by the COVID-19 pandemic through both the disruptions to migration flows resulting from the travel restrictions and the associated slightly higher mortality. From a rate of 1.7 per cent last year (2018–19), the pace of annual growth of the provincial population is projected to decrease to 1.3 per cent in 2019–20 and 1.2 per cent in 2020–21, before rising to 1.4 per cent in 2021–22. Thereafter, it is projected to ease gradually over time, reaching 0.9 per cent by 2045–46.
Net migration is projected to account for 83 per cent of all population growth in the province over the 2019–2046 period, with natural increase accounting for the remaining 17 per cent. In the second half of the projections, the contribution of natural increase will moderate once all baby boomers will have reached their senior years, and the number of deaths will start to increase more rapidly.
The number of seniors aged 65 and over is projected to almost double from 2.5 million, or 17.2 per cent of population, in 2019 to 4.5 million, or 23.3 per cent, by 2046. The growth in the share and number of seniors accelerates over the 2019–2031 period as baby boomers turn age 65. After 2031, the growth in the number of seniors slows significantly.
The number of children aged 0–14 is projected to increase moderately over the projection period, from 2.3 million in 2019 to 2.8 million by 2046. The children’s share of population is projected to decrease gradually from 15.7 per cent in 2019 to 14.8 per cent by 2046.
The number of Ontarians aged 15–64 is projected to increase from 9.8 million in 2019 to 11.9 million by 2046. This age group is projected to decline as a share of total population, from 67.1 per cent in 2019 to 61.9 per cent by 2046. As baby boomers continue to turn age 65, the growth in population aged 15–64 slows until 2027–28 and then accelerates slightly over the remainder of the projection.
The Greater Toronto Area (GTA) is projected to be the fastest growing region of the province, with its population increasing by 2.6 million, or 36.7 per cent, from 7.0 million in 2019 to over 9.5 million by 2046. The GTA’s share of provincial population is projected to rise from 47.9 per cent in 2019 to 49.8 per cent in 2046.
The five other regions are also projected to see growing populations over the projection period. With the exception of Central Ontario, the other regions are projected to grow at a slower pace than the provincial average. As a result, the share of Ontario’s total population that each of these four regions represents is projected to decline over time.
All regions will see a shift to an older age structure. The GTA is expected to remain the region with the youngest age structure as a result of strong international migration and positive natural increase.
