Canada's population fell by 102,436 people in 2025 — the first annual decline in Canadian history since Confederation. Statistics Canada confirmed the figure on March 18, 2026, reporting a January 1, 2026 total of 41,472,081 Canadians, down 0.2% from the previous year. For the first time, deaths outnumbered births in a quarterly period, and consecutive quarters of population loss marked Q3 and Q4 2025.
The number making headlines is striking. The implications for your retirement savings, CPP entitlements, and estate plan may matter more.
What Actually Drove the Decline
Three factors converged to produce a historic result. Non-permanent residents — international students, temporary workers, and permit holders — fell by 171,296 in the final quarter of 2025 alone, down 6% in a single quarter as the Carney government implemented its 2026–2028 immigration levels plan. Permanent immigration slowed to 83,168 new arrivals in Q4 2025, a 19.6% year-over-year drop.
Beneath the immigration story sits a longer-term structural shift: Canada's total fertility rate has fallen to 1.25 children per woman as of 2024, according to Statistics Canada's population estimates. That figure classifies Canada alongside South Korea and Japan in the "ultra-low fertility" category — the third consecutive year Canada has set a new record low. The replacement rate required to maintain a stable population without immigration is 2.1.
The combination produced Canada's first natural decrease on record: in Q4 2025, deaths exceeded births.
What a Shrinking Population Means for CPP and OAS
Canada's public pension system was designed for a different demographic reality. The Canada Pension Plan and Old Age Security both rely on intergenerational transfer — working-age Canadians fund benefits for retirees through payroll contributions and tax revenue.
The arithmetic shifts when the ratio of workers to retirees narrows. In 2026, the federal government projects $88.8 billion in OAS spending — an amount that flows, in part, to retirees with six-figure household incomes. The Parliamentary Budget Officer projected zero population growth for 2026 following the immigration cuts, removing the labour-force growth that historically underpins CPP sustainability.
For Canadians currently in their 40s and 50s, this is not a distant concern. If the working-age population shrinks while the retired population grows, the pressure to either raise contribution rates, reduce benefits, or push the eligibility age upward intensifies. The last major CPP reform — the gradual enhancement that began in 2019 — was designed assuming continued population growth.
A registered financial advisor can help you model how changes to CPP benefit timelines affect your overall retirement income, and whether your RRSP and TFSA balances can substitute for reduced public pension support.
The Fertility Rate and Estate Planning
Canada's 1.25 fertility rate has a less-obvious implication for estate planning: families are smaller. The average Canadian household in 2026 has fewer children than previous generations — and in some cases, none.
Estate structures that made sense for families with two or three children distribute assets differently when written for single-child households or for Canadians with no direct heirs. Trusts, charitable designations, blended family provisions, and beneficiary allocations all require reconsideration in the context of a society where the traditional two-child family is increasingly rare.
A notary or estate lawyer can review whether your current will reflects your actual family structure. The default rules under provincial succession law were not designed for ultra-low fertility demographics.
Regional Variation: Alberta Grows While Ontario Shrinks
Not all provinces experienced the decline equally. Alberta was the only province to grow in Q4 2025, gaining net interprovincial migrants for the fourteenth consecutive quarter. Ontario lost 54,890 people — 53% of Canada's total national loss. Quebec, British Columbia, and most Atlantic provinces also posted declines.
For Canadians considering interprovincial relocations — increasingly common as remote work makes geography flexible — these demographic trends affect local housing markets, tax environments, and service availability in ways that go beyond simple cost-of-living comparisons. Alberta's continued growth signals sustained demand for housing and services; Ontario's losses suggest continued pressure on urban housing prices, particularly in markets where supply has not kept pace with prior population growth.
A financial planner familiar with both federal and provincial tax rules can model the actual after-tax income impact of a province-to-province move against your existing asset base and projected retirement income.
Three Conversations Worth Having with a Financial Advisor
Canada's first population decline is a structural shift, not a one-year anomaly. The federal government has explicitly signaled that immigration levels will remain constrained through at least 2028. The fertility rate shows no sign of recovery. For Canadians managing household finances, retirement accounts, and estate plans, several conversations become more urgent.
Is your retirement income plan stress-tested against CPP/OAS changes? A scenario where public pension benefits are reduced or delayed by five years changes the required RRSP and TFSA balance substantially. Running that scenario now, with a professional, produces better outcomes than discovering the gap at age 65.
Does your estate plan reflect your actual family structure? Smaller families and more single-person households create different estate needs. If you last updated your will more than three years ago, it may not reflect 2026 reality.
Are you holding assets in the right province? As interprovincial migration accelerates, the tax and legal consequences of where you hold real estate, hold corporate assets, or plan to retire deserve review alongside demographic and market trends.
