Do I Really Need a Will If Everything Is Joint? (Ontario Reality Check)

It’s one of the most common things we hear in estate planning conversations: “We own everything jointly, so we probably don’t need wills, right?”
We understand the logic. Joint ownership with right of survivorship means the asset passes automatically to the surviving owner when one of you dies. No probate. No fuss. It feels like the problem is already solved.
But it’s not. The gap between that assumption and reality is where a lot of families run into serious problems.
How Joint Ownership Actually Works
When you own property jointly with right of survivorship in Ontario, the surviving owner does inherit automatically on the first death. Your home, joint bank accounts, and jointly-held investments pass outside your estate entirely — they don’t go through your will, and they don’t go through probate.
So far, so good. The problem is what happens next.
The “What Happens Next” Problem
Joint ownership protects you on the first death. It does nothing on the second.
When the surviving spouse dies (now holding everything in their name alone), that’s when your estate plan either exists or it doesn’t. Without a valid will, Ontario’s intestacy rules under the
For many couples, this means their estate ends up distributed in a way they never intended (particularly in blended family situations, where adult children from a first relationship may receive significantly less than expected, or more).
What About the Kids?
If you have children, especially minor children, a will does something joint ownership simply cannot: it names a guardian. Without a will, the question of who raises your children if both parents die at the same time is left entirely to the courts under the Children’s Law Reform Act. That’s a decision you almost certainly want to make yourself.
A will also lets you establish a trust for minor children so that assets are held and managed by someone you trust until the children reach an age where you’re comfortable with them managing money independently. Without that, assets may be paid out directly to a young adult who wasn’t expecting it and may not be ready for it.
Joint Ownership Can Also Create Complications
There are situations where joint ownership itself causes problems that a will could help address:
- Blended families: If your jointly-owned home passes to your spouse and they later remarry, the property may ultimately go to people you never intended.
- Family conflict: Without a clear will, disagreements about how to handle an estate often escalate. A properly drafted will reduces ambiguity and gives your family a clear path forward.
- Tax planning: Joint ownership doesn’t eliminate income tax. A well-structured estate plan can sometimes reduce the tax exposure on death in ways that joint ownership alone cannot achieve.
What a Will Actually Does for You
A will is not just a document that says who gets your stuff. It:
- Names an executor to administer your estate and deal with institutions, creditors, and the government
- Allows you to specify exactly how assets are distributed (including assets that don’t pass jointly)
- Names a guardian for minor children
- Can establish trusts to protect assets for children or family members who need structure around receiving an inheritance
- Can contain specific gifts, charitable donations, or instructions that reflect your wishes more precisely than any default rule would
Our Take
Joint ownership is a useful tool. But it’s not a substitute for a will. It’s a supplement to one. We’ve worked with families who’ve relied on joint ownership as their entire estate plan, and we’ve seen the complications that can follow when circumstances don’t unfold exactly as expected.
Getting a will done is not a major undertaking. It’s one of the most practical, caring things you can do for the people you’re leaving behind. And done right, it doesn’t need to be reviewed constantly. Just update it when your circumstances change.
