Canada’s Aging Population — The Demographic Shift Defining a Generation
Canada is in the midst of a demographic transformation that is reshaping its economy, healthcare system, pension architecture, and labour market in ways that will intensify for at least the next three decades. In 2025, 8.1 million Canadians were aged 65 and older, representing approximately 20.3% of the total population — a share that has nearly doubled from 12.5% in 2000 and is projected to grow to between 21.4% and 23.4% by 2030 as the last cohorts of the baby boom generation fully cross the retirement threshold. Canada’s median age stands at 41.7 years in 2025, up from 36.8 years in 2000, reflecting a population that is ageing steadily across every province and territory. The total age dependency ratio — the proportion of dependants (those under 15 and over 64) relative to the working-age population — reached 54.4% in 2025, meaning there are roughly 54 dependants for every 100 working-age Canadians, a ratio that has been climbing consistently and is expected to continue rising as the senior population grows faster than any other age cohort.
The fiscal and social consequences of this shift are already embedded in Canada’s national accounts and are accelerating. Federal spending on Elderly Benefits — encompassing Old Age Security (OAS), the Guaranteed Income Supplement (GIS), and the Allowance — is projected to reach $88.8 to $90.1 billion in 2026/27, representing nearly one in six dollars of total federal program spending and eclipsing every other single spending category in the budget. Population ageing alone is estimated to drive 20% of all future health care cost increases in Canada, with per-person spending on Canadians aged 65 and older running approximately three to five times higher than for those under 65. The old-age dependency ratio — the number of seniors relative specifically to the working-age population — reached 30.4 per 100 working-age adults in 2024 (up from 27.2 in 2020), a figure that will continue climbing as immigration, while slowing slightly, remains the country’s primary tool for maintaining workforce participation rates against the demographic headwind.

The 20.3% senior share of Canada’s population in 2025 marks a crossing of a threshold that demographers had long projected but that carries different implications in practice than in theory. The fact that seniors outnumbered children under 15 for the first time in 2015 was a watershed moment — and the gap has widened every year since. 8.1 million Canadians over 65 is not an abstract number: it represents a population requiring specialised healthcare, income support, housing, and social services at a scale that Canada’s public infrastructure was not designed to serve simultaneously. The 3.5% annual growth rate in the senior population between 2020 and 2025 outpaces the overall population growth rate of approximately 1–2% per year, meaning seniors are growing as a share of total population even as immigration continues to add working-age adults.
The life expectancy data reinforces the challenge’s longevity dimension. At 82.88 years average life expectancy in 2025, Canadians are living longer than at any previous point in history — and the most probable age of death is now 90 for the combined population, with the median age of death at 86.4 years. Seniors who reach age 60 can expect on average 18.5 additional healthy years of life, meaning the average Canadian retiring at 65 can anticipate drawing public pensions and consuming elevated healthcare for 20+ years. This longevity premium — beneficial at the individual level — compounds the fiscal pressure on CPP, OAS, GIS, and provincial health systems that must sustain an ever-larger senior population for an ever-longer average duration.

The old-age dependency ratio’s rise from ~18 in 2000 to 30.4 in 2024 captures in a single number the structural shift reshaping Canadian public finance. In practical terms, the ratio going from approximately 5.6 working-age adults supporting each senior in 2000 to 3.3 in 2024 means that the tax base funding CPP, OAS, GIS, and health transfers has become proportionally smaller relative to the benefit-drawing population with each passing year. By 2030, projections converge on a ratio of approximately 36 to 38 — meaning roughly 2.6 to 2.8 workers per senior — a compression that will intensify pressure on contribution rates, benefit design, and healthcare funding formulas simultaneously. The CIHI’s long-range projection from earlier analyses placed the ratio at approximately 2.84 workers per senior by 2025, a figure the data confirms has been reached ahead of schedule.
What makes Canada’s trajectory particularly acute is its pace. The ratio accelerated sharply from 2020 onward as the first wave of the baby boom cohort (born 1946–1965) moved fully into the 75-and-over bracket — the age group with the highest per-person healthcare consumption and longest social service dependency. The growth of Canadians aged 85 and older to over 833,000 in 2024, and the 100-and-over cohort nearly tripling since 2000 to 11,672, illustrates that not only is Canada’s senior population growing in size but also ageing within itself — creating a growing old-old population with substantially higher care needs than the young-old population that populated the dependency ratio calculations of earlier decades. Immigration continues to partially moderate the ratio — without the working-age immigrants Canada has admitted in recent years, the dependency ratio would already be materially higher.

Healthcare cost inflation driven by population ageing is the single largest structural fiscal risk embedded in Canada’s demographic transition. The Conference Board of Canada’s estimate that ageing alone will drive 20% of all future health care cost increases understates the challenge when combined with the complexity of care required by an older patient population. Seniors diagnosed with multiple chronic conditions — combinations of heart disease, diabetes, cancer, and dementia — require multiple specialist relationships, varied medication regimens, and elevated hospitalisation risks, all of which generate disproportionate system utilisation. The Canadian Medical Association has explicitly warned that older adults’ more complex care needs will fundamentally alter the health system’s workload composition even before total patient volumes are considered.
The trajectory of Elderly Benefits spending from $44.1 billion in 2015 to a projected $104.4 billion by 2029/30 represents a 136% increase in fourteen years, compounding at 6.24% annually — well above the growth rate of the Canadian economy. By 2026/27, these benefits will consume an estimated 17.1% of all federal program spending — a proportion that is projected to grow to 18.3% by 2029/30. The OAS/GIS programme has now become the single largest spending item in the federal budget, overtaking every other programme including health transfers and employment insurance. With the CPP maximum pension reaching $1,507.65 per month in January 2026 and OAS benefits indexed quarterly to the CPI, the total annual entitlement income available to a maximum-benefit Canadian retiree continues to grow — but the sustainability of the contribution base funding these programmes is under increasing analytical scrutiny as the dependency ratio climbs toward 38 per 100 by 2030.

The cohort-level breakdown of Canada’s senior population reveals dynamics that aggregate statistics can mask. The fastest-growing group within the senior population is not the 65–74 “young-old” cohort but rather the 85-and-older population, which exceeded 833,000 in 2024 and is growing at rates well above the broader senior average. This matters because the 85+ cohort has substantially higher healthcare needs, higher long-term care rates, and higher average social programme costs than younger seniors. The near-tripling of the 100-and-over population to 11,672 individuals is largely symbolic in fiscal terms but signals the direction of travel as medical advances continue to push out the boundaries of human longevity in a high-income country like Canada.
The contrast with the 0–14 age group — which has grown only marginally from 5.88 million in 2000 to 6.26 million in 2024 — is stark. Canada’s birth rate has not kept pace with the growth of the older population, meaning natural demographic balance is not being restored from within. The government’s reliance on immigration to maintain a working-age population large enough to fund retirement entitlements is therefore a structural policy requirement, not merely an economic aspiration. The rise in senior labour force participation from 6% in 2000 to 13.8% in 2020 — more than doubling — reflects both improved senior health and financial necessity for many older Canadians, and partially offsets dependency ratio pressures. However, with approximately 1 in 5 Canadian seniors living in low-income situations, the retirement security system remains imperfect even as its aggregate cost escalates — a tension that will define social policy debates in Canada for the remainder of the decade.
