When people think about "right of survivorship," they usually picture a house or a cottage. Far fewer think about their non-registered brokerage account — the one holding stocks, bonds, or mutual funds outside a registered plan — even though it can carry exactly the same right of survivorship, and exactly the same legal risk, as jointly held real estate. If your name is on a joint investment account with a parent, adult child, or anyone else, it's worth understanding how that account actually behaves when one owner dies.
The short answer is: it depends heavily on who the joint owner is and why the account was set up that way — not just on whose name appears on the statement.
Right of Survivorship Isn't a Real Estate Concept
A joint account with right of survivorship — sometimes labelled "JTWROS" on brokerage paperwork — works the same basic way whether the underlying asset is a house or a portfolio of investments: when one joint owner dies, the surviving owner is entitled to the whole account, automatically, outside the estate and outside probate. The mechanism is identical. What differs is how easy it is to prove what everyone actually intended when the account was opened.
Registered Plans vs. Non-Registered Joint Accounts
It's worth separating two things that often get confused:
- Registered accounts (RRSPs, RRIFs, TFSAs) with a named beneficiary pass directly to that named person on death through a beneficiary designation — a completely different legal mechanism than joint ownership, and one that generally isn't affected by the resulting trust issues discussed below.
- Non-registered joint investment or brokerage accounts — held in two names, without a beneficiary designation mechanism — rely on right of survivorship the same way a jointly held bank account or piece of real estate does.
This article focuses on the second category: accounts genuinely held in joint names, not accounts with a named beneficiary.
The Same Resulting Trust Risk Applies
Just as with a joint bank account, Ontario law's default assumption depends on the relationship between the joint owners:
- Between married spouses, jointly held investment accounts are generally presumed to reflect genuine joint ownership.
- Between a parent and an adult child, the law generally presumes the opposite — that the child holds their nominal interest in trust for the parent's estate — unless there's real evidence a gift was intended.
A parent who adds an adult child to a large non-registered investment account purely so the child can help manage things, without ever intending to give away half the portfolio, can end up with exactly the outcome they didn't want: the account treated as jointly owned, with the child keeping the whole thing on the parent's death, unless the resulting trust presumption is successfully raised and proven by other beneficiaries.
Why This Catches People Off Guard
Several features of investment accounts make this issue easy to miss:
- The account can be large. Unlike a modest chequing account, an investment portfolio can represent a meaningful share of someone's estate, so getting the ownership question wrong has outsized consequences.
- The paperwork looks routine. Adding a joint owner to a brokerage account is often a short administrative form, not something that prompts anyone to think through estate consequences.
- Growth complicates the picture. If the account's value has grown substantially since the joint owner was added, questions can arise about whether contributions, growth, and withdrawals were treated consistently with a genuine gift.
What Tends to Help Clarify Intent
- [ ] A written explanation, made at the time the joint owner was added, of why and what was intended
- [ ] Records showing how the account was actually used — did the added owner ever withdraw funds for their own purposes?
- [ ] Consistency between the account arrangement and the rest of the estate plan — does the will acknowledge the account, or is it silent?
- [ ] Advice from the investment firm and a lawyer before adding a joint owner to a substantial account, rather than after a dispute has already started
Frequently asked questions
If my broker's form says "joint with right of survivorship," does that settle the question?
The account-opening paperwork is meaningful evidence, but it isn't automatically the final word — especially in a parent-and-adult-child situation, where Ontario courts start from a presumption against a gift regardless of what a standard account-opening form says. Other evidence of intent still matters.
Does it matter whether the account is registered or non-registered?
Yes. A registered plan with a named beneficiary uses a different legal mechanism (a beneficiary designation) than a jointly titled account, and generally isn't subject to the same resulting trust analysis. Make sure you know which structure actually applies to each of your accounts.
Can other beneficiaries challenge a joint investment account after the fact?
Yes. Just as with a joint bank account, other beneficiaries of an estate can raise the resulting trust presumption during estate administration, putting the burden on the surviving joint account holder to produce evidence that a gift was genuinely intended.
Does a joint investment account avoid probate?
Generally, yes — like other assets that pass by survivorship, a genuinely joint investment account passes directly to the surviving owner outside the estate, and its value is generally not counted toward the estate value used to calculate Estate Administration Tax. That benefit assumes the joint ownership itself isn't successfully challenged.
