Joint Tenants vs. Tenants in Common: How You Own Your Home Matters

November 26, 2025

Why a Simple Checkbox on Your Deed Can Overrule Your Will

When you buy a home in Ontario, you sign a mountain of paperwork. Amidst the mortgage documents, land transfer tax affidavits, and insurance forms, there is a critical legal election that many buyers glaze over in the excitement of the moment.

Your lawyer will ask you a simple question: "How do you want to take title?"

You are usually given two choices: Joint Tenants or Tenants in Common.

To most people, these sound like interchangeable legal jargon—a distinction without a difference. But from a legal perspective, they are worlds apart. The option you choose dictates who actually owns your home, how it can be sold, the taxes your estate will pay, and—most importantly—what happens to your biggest asset when you pass away.

In this guide, we will break down exactly what these terms mean, the hidden tax traps of each, and how to choose the right structure for your family.

Option 1: Joint Tenants (The "Standard" for Couples)

Joint Tenancy is the most common form of ownership for married couples in Ontario. The defining characteristic of this structure is "unity." In the eyes of the law, you do not own a specific "share" of the house (e.g., 50%); instead, you both own 100% of the property together as a unified whole.

The Key Feature: The Right of Survivorship

The engine that drives Joint Tenancy is the Right of Survivorship.This legal principle states that if one joint owner dies, their interest in the property effectively evaporates, and the surviving owner is automatically left as the sole owner of the entire property.

This process happens instantly at the moment of death. It does not require a court order, and it does not look at your Will.

The Pros:

Speed and Simplicity: The property transfers automatically. The survivor simply files a "Survivorship Application" on title to remove the deceased's name.
Probate Tax Savings: This is the biggest financial driver. In Ontario, assets that pass through your Will are subject to Estate Administration Tax (Probate Tax), which is roughly 1.5% of the asset's value. Because a Joint Tenancy home bypasses the Will, it bypasses this tax. On a $1,000,000 home, that is an immediate savings of $15,000 in taxes.

The Cons (The "Blended Family" Trap):

Because the property transfers automatically by right of survivorship, it overrules your Will entirely.

This is a frequent point of failure for blended families (couples with children from previous relationships).

Scenario: John and Sarah marry. Both have children from prior marriages. They buy a home as Joint Tenants. John's Will states, "I leave my half of the house to my children."
The Outcome: If John dies first, Sarah automatically owns 100% of the house. John's clause in his Will is invalid because the house never entered his estate. Sarah is now the sole owner and can leave the house entirely to her children, effectively disinheriting John's family.

Option 2: Tenants in Common (The Strategic Choice)

Tenants in Common is a very different legal arrangement. Here, each owner holds a specific, separate percentage of the property. It could be 50/50, or it could be 99/1 (common when parents act as guarantors for a child).

The Key Feature: No Right of Survivorship

If you die as a Tenant in Common, your share does not disappear or go to the other owner. Instead, your specific percentage acts like any other asset you own: it flows into your estate and is distributed according to your Will.

The Pros:

Control: You have absolute authority over your share. You can leave it to your children, a sibling, or a charity. This is the only safe way for blended families to ensure their respective children inherit their share of the equity.
Flexibility: It allows for unequal ownership. If one friend puts up 75% of the down payment and the other puts up 25%, a Tenancy in Common allows the deed to reflect that reality accurately.

The Cons:

Probate Tax: Because your share passes through your estate, it is subject to the 1.5% Estate Administration Tax. However, for many clients, paying 1.5% tax is a small price to pay to ensure the remaining 98.5% actually goes to the correct beneficiaries.

The Hidden Traps: What Most Lawyers Won't Tell You

Beyond the basics, there are two complex legal traps that commonly catch Ontario homeowners off guard.

Trap #1: The Capital Gains "Gift"

We often see aging parents add an adult child to the title of their home as a "Joint Tenant" to avoid probate fees. They think they are being smart. Unfortunately, they often accidentally trigger a massive income tax bill.

If your child does not live in the home, they cannot claim the Principal Residence Exemption on their share.

Example: You add your son to your title. You bought the house for $200,000, and it is now worth $1,000,000. When you pass away or sell the home, your son's 50% share may be subject to Capital Gains Tax on the growth in value. You might save $15,000 in probate fees, only to cost your family $50,000+ in income tax.

Trap #2: The "Resulting Trust" (The Pecore Principle)

In a famous Supreme Court case (Pecore v. Pecore), the court ruled that when a parent gratuitously adds an adult child to an asset, the law presumes the child is holding it in trust for the estate, not as a true gift.

This means that even if you make your daughter a Joint Tenant, your other children could sue after your death, claiming the house should still be divided equally among all siblings. Without clear legal documentation (like a Deed of Gift) prepared at the time of the transfer, your "simple" probate-avoidance strategy could lead to a $100,000 family lawsuit.

The Boutique Advantage: Unilateral Severance

This is where having a dedicated lawyer at Cabinet Sauvé Law becomes your greatest asset. We know that life changes. Sometimes, a marriage breaks down, but the divorce isn't final for months or years.

In that dangerous window of separation, if you hold the matrimonial home as Joint Tenants and you pass away, your estranged spouse could inherit the entire home—leaving your children or other heirs with nothing.

The Solution: In Ontario, a lawyer can perform a "Unilateral Severance."We can register a deed transferring your interest from yourself to yourself. This sounds odd, but legally, it breaks the "joint" nature of the title and instantly converts it to a Tenancy in Common.

The Result: You regain control of your 50%. You can now leave it to your children in your Will.
The Power: Crucially, you can do this without your spouse's consent. It is a powerful, immediate shield we can deploy to protect your estate during a separation.
