Should Couples Choose Individual or Joint Investment Accounts?

Losing a spouse is devastating. Losing access to the family’s savings on top of that can be crushing—and it happens more often than many Canadians expect. Imagine waking up after your partner’s death to find a $400,000 investment account frozen. Weeks and months pass while the estate goes through probate, thousands of dollars in fees are deducted, and you’re left scrambling to cover everyday expenses. A common cause is simple: non-registered investment accounts held in only one spouse’s name.

The hidden snag in non-registered accounts

When a non-registered investment account is held in a single owner’s name, it does not automatically pass to a surviving spouse. Instead, the account becomes part of the deceased person’s estate and is subject to probate—the court-supervised process that validates the will and confirms the executor’s authority. Depending on the province, probate can take months or more than a year, during which the surviving spouse may be unable to access the funds.

That delay comes with real costs. Probate fees differ by province: for example, Ontario charges roughly 1.5% of the estate’s value, while British Columbia charges a set rate per $1,000 of estate value above an exemption threshold. On larger accounts, those fees can amount to several thousand dollars, money that is deducted before beneficiaries see a cent.

A real-life example

Consider John and Mary from Vancouver. John’s non-registered investment account held $400,000 and Mary had her own $300,000. When John died suddenly, his account was frozen and Mary couldn’t access the funds. The executor applied for probate, and the process in British Columbia stretched on for ten months. During that period Mary covered household expenses from her savings and turned to a line of credit. More than $5,000 in probate fees were taken from John’s estate. What should have been a straightforward transfer between spouses became a drawn-out ordeal that added stress and financial strain during an already difficult time.

Joint ownership: A simple fix

Joint ownership with rights of survivorship can eliminate this problem. If John and Mary had held their investment account jointly, the assets would have passed immediately to the surviving spouse without a freeze or probate fees. Mary would have had uninterrupted access to cover living costs and bills.

Many people worry that changing an individual account to joint ownership will trigger taxes. In most cases it does not create an immediate tax event: the adjusted cost base and unrealized gains generally carry over. A deemed disposition typically occurs only when the assets are sold or at death, and spouses can often take advantage of a spousal rollover that lets the surviving spouse inherit at the original cost base. For many married or common-law couples, joint ownership is a straightforward and effective estate planning tool.

When one spouse is a U.S. citizen

For cross-border couples, joint ownership remains an option but brings additional tax and reporting complexities. Key points to consider include:

  1. Cost base continuity: Transferring assets into a joint account does not reset the original purchase price; the adjusted cost base generally carries forward.
  2. No immediate Canadian or U.S. tax event: Simply moving an account into joint ownership typically does not create an immediate taxable event in either jurisdiction.
  3. Canadian attribution rules: The Canada Revenue Agency may continue to attribute investment income to the original Canadian owner for tax purposes.
  4. U.S. tax reporting: U.S. tax reporting rules can complicate matters, especially when income is reported under one person’s Social Security number or tax ID. If a couple does not file jointly in the U.S., adjustments may be needed to avoid erroneous notices or mismatches with reported income.
  5. Gift-reporting thresholds: If a Canadian spouse effectively transfers more than a prescribed U.S. dollar threshold to a U.S. citizen spouse, additional reporting (for example, certain IRS informational forms) may be required. These filings are informational in nature but missing them can lead to penalties, so cross-border couples should be aware of requirements.

The bottom line: While transfers between spouses are usually not taxable, cross-border reporting and compliance costs can add up. In some provinces, probate savings from joint ownership may outweigh the costs of extra tax filings, but every family’s situation is different. Couples with cross-border ties should consult a cross-border advisor or qualified tax professional to weigh probate savings against additional compliance obligations.

Why children shouldn’t be added jointly

Some people try to avoid probate by adding adult children as joint owners on their accounts. It can seem like an easy solution, but that approach often creates new and potentially serious problems.

When you add a non-spouse as a joint owner, tax rules commonly treat the change as a deemed disposition. For example, a widow with a $300,000 non-registered account who adds an adult child as joint owner may trigger a deemed sale of half the account at current market value, creating a large taxable capital gain without receiving any cash to cover the tax liability.

Other risks include:

  • Family conflict: Other heirs may feel excluded, which can lead to resentment or legal challenges.
  • Loss of control: Once a child is added as a co-owner, they legally own a share of the asset. Relationships and circumstances can change, and reversing the ownership may be difficult or impossible without the co-owner’s consent.

Safer alternatives include keeping accounts in your own name and using clearly drafted wills, trusts, and beneficiary designations on registered accounts and life insurance policies. These tools preserve control, avoid immediate tax consequences, and reduce the risk of family disputes while still directing assets where you want them to go.

The takeaway

Non-registered individual accounts can leave surviving spouses facing long delays and significant probate fees just when they need access to funds most. Holding assets jointly with a spouse, where appropriate, can provide immediate access, seamless transfer on death, and tax deferral through spousal rollover rules. For cross-border couples and for those considering adding children as joint owners, the decision requires careful consideration of tax, reporting and family dynamics.

Taking a little time now to plan account ownership, beneficiary designations, and your estate documents can save your loved ones months of stress and thousands of dollars in fees later. In a time of grief, that practical peace of mind is invaluable.
