Right of Survivorship in Ontario: What It Means for Your Estate Plan

One of the most common misconceptions in Ontario estate planning is that your will controls everything you own. For many homeowners, the most valuable asset they hold — the family home — may bypass the will entirely. That is the right of survivorship at work, and understanding it is essential before you assume your estate plan is complete.

What Is the Right of Survivorship?

The right of survivorship is the legal mechanism that operates when a joint tenant dies. In a joint tenancy, all co-owners hold the property as a single, undivided whole — no one has a separate fraction. When one joint tenant dies, their interest does not become part of their estate. Instead, by operation of law, the property vests automatically in the surviving joint tenant(s).

The process requires no probate, no executor action on the property itself, and no will. The survivor simply registers what is called a survivorship application on title through the Ontario land titles system, attaching proof of death (such as a death certificate), and becomes the sole registered owner.

Why Does It Matter for Your Will?

Your will has no authority over property held in joint tenancy. Even if your will expressly states "I leave my share of 123 Main Street to my daughter," that direction is legally ineffective if the property is held jointly with someone else. The right of survivorship operates first — before the will has any say.

This is not a flaw; it is by design. Many spouses choose joint tenancy precisely because they want the home to transfer to each other automatically, avoiding estate administration delays and estate administration tax (what Ontario calls probate fees) on the property value.

The risk arises when people forget this or when circumstances change — second marriages, estranged co-owners, or a desire to leave a share to children.

The Probate Avoidance Benefit

Estate Administration Tax in Ontario (as of writing — verify the current rate with the Ontario Ministry of Finance) is levied on the value of the estate that passes through the court process. Because jointly held property passes by survivorship and never forms part of the estate, it escapes this tax.

For a home worth several hundred thousand dollars, this can represent a meaningful saving. That said, probate avoidance should not be the only reason to choose joint tenancy. If the structure does not fit the estate plan — for example, if you want to protect a share for children from a prior relationship — the tax saving is not worth the planning problem it creates.

When the Right of Survivorship Works Well

• Spouses buying together who want the survivor to have immediate, unencumbered ownership without estate administration.
• Unmarried partners who want to ensure the other person inherits the home, particularly where family members might otherwise contest the estate.
• Simplicity: avoiding the home going through the estate can ease administration significantly, especially when the estate has other complexities.

When the Right of Survivorship Can Cause Problems

1. Blended Families

If you remarry and hold your home jointly with your new spouse, your children from a prior relationship have no claim to the home when you die. Your share passes to your new spouse by survivorship — full stop. This is a common source of family conflict and litigation.

2. Simultaneous Death

What happens if both joint tenants die at the same time (for example, in an accident)? Ontario's Succession Law Reform Act contains a presumption that addresses simultaneous death — but the outcome can be counterintuitive. Wills and co-ownership agreements should address this scenario explicitly.

3. Unequal Contribution

Joint tenancy requires equal shares. If one person contributed 80% of the purchase price and both owners die without further planning, the 80% contributor's estate does not recover the extra contribution — the survivors take equally. This can be addressed with a tenancy-in-common structure or a co-ownership agreement.

4. Incapacity, Not Death

Survivorship only operates on death. It does nothing to address what happens if one joint tenant becomes incapacitated. A Power of Attorney for Property is the instrument for that.

The Survivorship Application Process

After a joint tenant dies, the surviving owner (or their lawyer) registers a survivorship application at the land registry office. The application requires:

• Proof of the deceased joint tenant's death (typically a death certificate)
• Confirmation of the property description and registration number
• Registration fee (verify the current amount with ServiceOntario)

Once registered, the title is updated to show the survivor as sole owner. The process is generally faster and less expensive than administering an estate through probate — one of the key practical advantages of joint tenancy.

Planning Around the Right of Survivorship

If you want the home to not pass entirely to your co-owner on your death, your main options are:

1. Sever the joint tenancy — convert to tenancy in common, then address your share in your will.
2. Sign a co-ownership agreement — contractually address what happens if one owner dies, including any option for your estate to sell the share back to the survivor at a specified price.
3. Review and update your will — once the joint tenancy is severed, your will controls your share, so make sure it says what you actually want.
