Why Investment Growth Alone May Not Be Enough to Protect Family Wealth
Canadian households hold trillions of dollars in financial assets, and a large share of that wealth sits in stocks, bonds, and mutual funds built for long-term growth. Markets have rewarded patient investors over time, and it is easy to assume that steady contributions and compounding returns are enough to secure a family’s future. But growth strategies are built to manage market risk. They are not designed to absorb the sudden, personal risks that can interrupt a family’s finances long before the market ever gets a chance to recover.
A well-built diversified portfolio can smooth out volatility across asset classes, but it cannot replace a paycheque, cover a medical bill, or keep a business running while an owner recovers from illness. That is the gap insurance is meant to fill. Below are five financial risks that investments alone often cannot fully address, and how coverage can work alongside a portfolio to protect income, preserve assets, and support the people who depend on it.
1. Premature Death
The most direct risk to family income is the early death of a primary earner. A portfolio built for retirement in twenty or thirty years is not liquid enough, or large enough, to replace decades of missing income on short notice. Life insurance specialists note that Sage Advisory Corp. founder Eric Benchetrit has observed that the role of life insurance tends to grow rather than shrink as a family’s wealth increases, since larger estates often carry larger obligations, debts, and tax liabilities that need to be settled quickly. A death benefit provides immediate cash when it is needed most, without forcing a family to sell investments during a downturn.
2. Disability
Disability is statistically more likely than early death for working-age Canadians, yet far fewer households prepare for it. Government guidance from the Financial Consumer Agency of Canada indicates that long-term disability coverage typically replaces between 60 and 85 percent of a person’s income, since provincial health plans generally cover medical treatment but not lost wages. Industry research has also found that a 30-year-old in Canada faces a meaningfully higher chance of becoming disabled before age 65 than of dying in that same window. Without income replacement coverage, a prolonged disability can force a family to draw down retirement savings years ahead of schedule.
3. Critical Illness
A serious diagnosis brings costs that extend well beyond what public healthcare covers, including travel, home modifications, and time away from work during recovery. A 2025 Ipsos survey conducted for RBC Insurance found that nearly one in three Canadians would exhaust their savings within six months of a major health setback, and that the large majority of Canadians carry no critical illness coverage at all. Data compiled by the Canadian Cancer Society shows that roughly one in two Canadians will receive a cancer diagnosis in their lifetime. Critical illness insurance pays a lump sum on diagnosis, giving a family breathing room to focus on recovery instead of liquidating investments at an inopportune time.
4. Business Interruption
For entrepreneurs and business owners, personal and business wealth are often deeply connected, which means an operational disruption can threaten both at once. A 2024 survey by TD Insurance, conducted with Maru Public Opinion, found that close to one in five small business owners consider interruption their biggest risk, yet almost 40 percent carry no business insurance to address it. Coverage such as business interruption or key person insurance can replace lost revenue or offset the cost of losing a critical employee, helping a company stay solvent while it recovers rather than drawing down the owner’s personal investment accounts.
5. Unexpected Estate Expenses
Settling an estate often triggers costs that families do not anticipate, including probate fees, legal work, and capital gains taxes owed on the deemed disposition of assets at death. Wealth advisors writing for Canadian Family Offices have pointed out that life insurance can act as a hedge against these tax liabilities, giving beneficiaries the liquidity to pay what is owed without selling real estate, a family business, or other assets at a disadvantageous time. Without that liquidity, heirs may be forced into rushed sales that undermine the very wealth the family worked to build.
Building Coverage Around a Portfolio
Each of these risks shares a common thread: they create a need for cash at a moment when selling investments would be costly, poorly timed, or simply impossible. Insurance is not a competitor to investing. It is a complement that protects the plan already in place, so that a portfolio can keep growing instead of being interrupted to cover an emergency. Working through insurance considerations for buyers alongside an investment strategy helps ensure that both sides of a financial plan are working toward the same goal, rather than operating in isolation.
Family responsibilities, business interests, and financial circumstances change over time, and coverage that made sense a decade ago may no longer match current needs. A growing family, a new business venture, or a shift in estate value can all signal that it is time to review existing policies. Regularly revisiting both the investment strategy and the insurance coverage that supports it helps ensure that a family’s wealth is protected from more than just market swings, and prepared for the risks that markets were never designed to cover.
