When two or more people purchase a property together in Ontario, they need to decide how title will be held. This is not a formality — it is a legal decision with real implications for what happens to the property if one owner dies, if the relationship breaks down, or if one party wants to sell their share.

The two options in Ontario are joint tenancy and tenancy in common. Your lawyer will ask you about this at closing, and it is worth understanding the difference before you get to that conversation rather than making a rushed decision at the table.

Joint Tenancy — What It Means and When It Makes Sense

In a joint tenancy, all owners hold an equal, undivided interest in the entire property. Two owners each hold 50%. Three owners each hold one third. The shares must be equal — you cannot hold title as joint tenants with unequal ownership percentages.

The defining feature of joint tenancy is the right of survivorship. If one joint tenant dies, their interest in the property automatically transfers to the surviving joint tenant or tenants — outside of the estate, without going through probate, and regardless of what the deceased person’s will says. The property does not become part of the estate; it passes directly to the surviving owners by operation of law.

This makes joint tenancy the standard choice for married couples and common-law partners purchasing a home together. If one partner dies, the surviving partner automatically becomes the sole owner without delay, legal complexity, or probate fees. The property does not need to pass through the estate, which means it is not subject to estate administration tax on that asset and is not accessible to estate creditors.

Joint tenancy also has implications during the owners’ lifetimes. Either joint tenant can sever the joint tenancy unilaterally — converting it to a tenancy in common — without the other owner’s consent, simply by registering a document on title. This is worth understanding if you are purchasing with a partner and the relationship later changes.

Tenancy in Common — What It Means and When It Makes Sense

In a tenancy in common, each owner holds a distinct, separately transferable share of the property. The shares do not have to be equal — one owner might hold 60% and another 40%, or any other division the parties agree to. Each owner’s share is their own property, which they can sell, mortgage, or leave to whoever they choose in their will.

The key difference from joint tenancy is that there is no right of survivorship. When a tenant in common dies, their share of the property does not automatically pass to the other owners — it passes according to their will, or if there is no will, according to Ontario’s intestacy rules. The deceased owner’s share becomes part of their estate.

Tenancy in common is typically the right structure for people purchasing together who are not in a committed relationship — business partners, friends, siblings, or investors. It allows each owner to hold a share that reflects their financial contribution, leave their share to their own heirs, and deal with their interest independently of the other owners.

It is also sometimes chosen by couples who want to ensure their share of the property passes to their own children from a previous relationship rather than automatically to a surviving spouse. This comes up frequently in blended family situations and is worth a specific conversation with your lawyer and estate planner if it applies to you.

Practical Implications — What Happens If Things Change

The choice between joint tenancy and tenancy in common is not necessarily permanent, but changing it later requires deliberate action and legal work. Understanding the implications from the start is better than discovering them when circumstances force the issue.

If joint tenants want to change to tenancy in common — perhaps because their relationship has changed or because estate planning considerations have shifted — one owner can sever the joint tenancy by registering a transfer on title. The other owner does not need to consent. Once severed, the joint tenancy becomes a tenancy in common and the right of survivorship no longer applies.

If tenants in common want to change to joint tenancy, both owners need to agree and the transfer needs to be registered on title — it cannot be done unilaterally.

If one tenant in common wants to exit the ownership arrangement entirely and the other owner does not agree to a sale or buyout, they can apply to the court for a partition and sale — a legal process that can force the sale of the property and division of the proceeds. This is a last resort and genuinely disruptive, but it is available. It underscores why the choice of ownership structure and the relationship between co-owners matters from the beginning.

What Your Lawyer Will Ask You — and What to Think About Before Closing

At closing, your real estate lawyer will ask how you want to hold title. If you have not discussed it beforehand, you may feel pressure to make a quick decision. The answer depends on your situation, your relationship with your co-owner, and your estate planning goals — and it is worth thinking through before you are sitting at a closing table.

A few questions to consider before that conversation. Are you purchasing with a spouse or long-term partner with whom you want the simplest possible survivorship arrangement? Joint tenancy is likely the right choice. Are you purchasing as an investment with a business partner or friend, where each party’s share should be independently owned and transferable? Tenancy in common is almost certainly more appropriate. Do you have children from a previous relationship whose inheritance you want to protect regardless of what happens to your relationship with your co-purchaser? Speak to an estate lawyer about the right structure before you close.
