Joint Tenancy vs Tenants in Common: How Ontario Co-Owners Hold Title

Two people buying a property together in Ontario hold it one of two ways. Joint tenancy means when one of you dies, the other automatically owns the whole thing, and it never touches the estate. Tenants in common means each of you owns a defined share that passes through your will to whoever you name. Most married couples buying a home together choose joint tenancy. Most friends, siblings, business partners and second marriages should at least look hard at tenants in common. Your lawyer puts this on the transfer at closing, and changing it later is possible but not free.

The one difference that matters most

It is called the right of survivorship. Under joint tenancy, a deceased owner’s interest does not become part of their estate. They simply come off title and the survivor owns all of it. There is no will to read, no executor to appoint, no probate application for that asset.

Tenants in common works the opposite way. Your share is yours. You can sell it, mortgage it or leave it to anyone you like, and when you die it goes through your estate to whoever your will names. Shares also do not have to be equal. Two people can hold 70 and 30 if that is what they each put in.

What the probate difference is worth

Ontario charges Estate Administration Tax on the value of assets passing through an estate. Nothing on the first $50,000, then $15 per $1,000, which works out to 1.5 percent, on everything above that. Property held in joint tenancy skips it, because the interest never enters the estate.

Ontario Estate Administration Tax: nil on the first $50,000, then $15 per $1,000. Figures show tax on the half interest alone, assuming a tenants in common holding and no other estate assets. Rates current as of August 2026. Your lawyer or accountant should run your actual numbers.

Worth keeping in proportion. On an $800,000 property that is $5,250, which is real money but it is well under one percent of the asset. People sometimes structure ownership badly to dodge a probate bill that turns out to be smaller than the problem they created. The tax is one input, not the decision.

Severance, or how a joint tenancy comes apart

A joint tenancy is not permanent. Any one owner can sever it on their own, without the other owner’s agreement, which converts the holding to tenants in common. The right of survivorship disappears and each party keeps their proprietary half. To be effective against third parties, the severance has to be registered on title.

This surprises people, and it is the reason we tell separating couples to raise it with their family lawyer immediately rather than in six months. If nothing is severed and one spouse dies mid separation, the survivor can end up owning the whole property regardless of what either will said.

The matrimonial home has its own rules

Ontario’s Family Law Act treats the matrimonial home differently from every other asset. A spouse cannot sell or mortgage their interest in it without the other spouse’s written consent, whatever title says. Courts have held that severing a joint tenancy is not the same as disposing of an interest, so a spouse can still sever unilaterally, but the consent requirement on a sale or mortgage stands.

There is also a provision that catches people out. Where a spouse holds a matrimonial home in joint tenancy with someone other than their spouse, a parent or a sibling for instance, the joint tenancy is deemed severed immediately before death. The survivorship the family was counting on does not operate. If that describes your title, it is worth a conversation with an estates lawyer.

How we would think about it

Married and buying a home together with no children from previous relationships: joint tenancy is the usual answer, and the probate saving and simplicity both point the same way.

Second marriage, children from a first: tenants in common deserves a serious look, often paired with a spousal trust in the will. Joint tenancy hands the whole property to the surviving spouse, and whatever your will says about your children is simply overridden. That is the single most common regret we see.

Friends, siblings or investors buying together: tenants in common, almost always, with a written co-ownership agreement covering who pays what, how one party exits, and what happens if somebody wants out. Unequal shares are common here and joint tenancy cannot express them.

Parent going on title to help a child qualify: get advice first. It affects the parent’s principal residence exemption, exposes the property to the parent’s creditors, and can trigger land transfer tax on a later change. The financing convenience is real and the tax consequences can be larger than the benefit.

The counterpoint on all of this: joint tenancy is popular because it works, cheaply, in the ordinary case. Two spouses, one home, one set of beneficiaries, and the survivor gets the house without a court process at the worst possible time. What would change our thinking is any complication in the family structure, unequal contributions, or a property held with someone other than a spouse.

One caveat we will repeat: we are real estate brokers, not lawyers or tax advisors. Everything above is the general shape of the rules in Ontario as of August 2026. The instruction on your transfer should come from your own lawyer, who will ask questions about your family and your will that we do not.
