3.2 million households. Almost no formal arrangements.
Canada has approximately 3.2 million multigenerational households — families where grandparents, adult children, and grandchildren share a roof. That number has grown steadily every census cycle, accelerated by housing costs, an aging population, and the economic pressure of the pandemic years.
The families in those households are not, in most cases, there by preference. They are there because the math stopped working for at least one generation, and proximity to each other was the only viable answer.
The wealth in these households is almost entirely illiquid. The elder generation holds the home equity — sometimes over a million dollars on paper. The younger generation holds the income. Neither can easily access what the other has, and nothing governs the exchange between them.
"His recognition isn't a whole lot. I can't wash dishes with it."
— Windsor-Essex resident, describing contribution imbalance in a multigenerational household
The generation holding income is also holding the most debt.
Canadian households aged 35–44 carry the highest debt-to-income ratio of any age group: $2.46 of debt for every dollar of disposable income. This is the generation most likely to be co-living with both aging parents and young children — and least likely to have financial slack.
Meanwhile, the senior generation has the opposite problem: strong credit profiles (average score 750 for those over 65), substantial home equity, and constrained cash flow. The home is worth more than it has ever been. It cannot be eaten, and it cannot pay for the PSW who comes Tuesday and Thursday.
Three households. The same missing document.
The arrangement looks different in every home. What doesn't change is the absence of anything written down.
Grandparents (both retired) own the home outright. Adult daughter and her husband contribute $1,800/month to household expenses and provide all transportation, medical coordination, and grocery management. The daughter also works full-time. Nothing is documented. If the grandparents pass, two other siblings — who live elsewhere — will inherit equal shares of the home.
Three-generation household: grandmother, adult son and his partner, two teenage grandchildren. Son earns manufacturing income. Partner stays home, manages the household, cares for the grandmother, and supervises the teenagers' remote schoolwork. Grandmother receives OAS and GIS. No agreement exists about what happens when the grandmother needs more intensive care, or when the teenagers leave, or if the son's income changes.
Adult daughter returns home after a separation, bringing two children. Mother is widowed, owns the home, and provides childcare while the daughter works. The arrangement was meant to be temporary. Three years later it is permanent. There is no agreement about the daughter's rent contribution, the mother's care equity, or what happens to the home when the mother eventually needs care herself.
These households are not failing. They are functioning. The problem is that nothing protects the people inside them when something changes — and something always changes.
Decades of care. No documentation. Then a dispute.
The scenario plays out the same way across families and cultures: one family member provides years — sometimes decades — of unpaid care. Drives to appointments. Manages medications. Coordinates care workers. Absorbs the household. Does this while raising children and sometimes while working.
When the elder passes, siblings who were not present inherit equal shares. The courts have no mechanism to recognize the caregiving contribution without documentation. A handshake is not evidence.
A Household Equity Agreement is not a legal document and does not change how estates are distributed under Ontario law. But it is a written, dated, signed record — created before anyone needed it — that describes what actually happened in that household for however many years it operated.
That record changes the nature of a family conversation. It does not guarantee an outcome. It provides a basis for one.
A common value for three different currencies.
The core problem in every multigenerational household is that contributions come in forms that can't be directly compared. Money is visible. Care hours are invisible. Household labour is somewhere in between. When there's no common unit, the person whose contribution is most legible — usually the one bringing income — appears to be contributing most. The others disappear.
Parvus converts all three currencies to a common equity value using Windsor-Essex market rates for PSW care ($20/hr), childcare ($18/hr), domestic labour ($16/hr), and teen supervision ($12/hr). Every household member gets an equity score. The agreement records those scores, the method used to produce them, and the triggers that should cause the household to revisit the arrangement.
