Joint Tenancy vs. Tenants in Common

How to navigate co-ownership of real property.


When two or more people buy property in Ontario, they must decide how they will hold title. That choice is often made quickly during a purchase, but it has important consequences for estate planning, family law, and taxes. The two main options are joint tenancy or else tenancy in common.

 

Joint Tenancy

 

In a joint tenancy, each owner holds an equal interest in the entire property. The key feature is the right of survivorship. When one co-owner dies, their interest passes automatically to the surviving owner(s).  The deceased co-owner’s interest in the real property does not form part of the deceased’s estate and does not pass under their Will.

 

Joint tenancy is the common option for spouses. A joint tenancy simplifies matters on death because the real property transfers automatically and avoids the Estate Administration Tax (also known as “probate fees”). A joint tenancy overrides the deceased co-owner’s Will, even where they purport to deal with their co-ownership interest.  Clients must be careful that their choice of tenure aligns with broader estate planning goals or where the co-owners have contributed unequally to the purchase of the real property.

 

Tenancy in Common

 

Tenancy in common offers greater flexibility, but no survivorship. Owners can hold unequal shares, often based on how much value each person contributed toward the purchase. While each owner has a defined share, all have the right to use and occupy the entire property.

 

Without survivorship, a deceased co-owner’s share passes into their estate and is subject to their Will (or Ontario’s intestacy rules if there is no Will). This preserves control over who inherits the interest. Estate Administration Tax will almost certainly apply.

 

Tenancy in common is often appropriate where:

 

  • Owners contribute different amounts
  • Co-owners are not spouses (or do not intend to benefit their co-owner on death)
  • The property is primarily an investment
  • One co-owner wants their interest to pass to someone other than the other co-owner

 

Because co-owners may have different goals or timelines, a written co-ownership agreement is advisable. Such an agreement can address expense sharing, mortgage obligations, use of the property, and how disputes or buyouts will be handled. Without one, disagreements can lead to court proceedings under the Partition Act (Ontario), which may result in a forced sale.

 

Changing Ownership Structure

 

A joint tenancy can be converted into a tenancy in common by “severing the joint tenancy”. This can be accomplished by agreement of the co-owners. But more often than not, one co-owner takes unilateral steps to terminate the joint tenancy.

 

Moving from tenancy in common to joint tenancy requires the co-owners to agree.

 

Choosing the Right Approach

 

There is no universal solution. The right structure depends on factors such as:

 

  • Who should inherit each co-owner’s share
  • How much each co-owner is contributing
  • Estate planning and probate considerations
  • Family law implications
  • Whether a co-ownership agreement is needed
  • Long-term plans for the property

 

While these issues are best addressed at the time of purchase, ownership can be restructured later if circumstances change. Co-owning property can work well — but only if the legal structure aligns with the owners’ financial and estate planning objectives.  Careful planning at the outset can prevent unintended consequences later.

In Ontario, ODSP recipients are generally not permitted to hold more than $40,000 in non-exempt assets without risking their benefit qualification. As a result, receiving an inheritance—especially an unexpected one—can be stressful and confusing. Many recipients are left wondering whether the inheritance will reduce or interrupt their ODSP support. When families don’t know whether their intended-beneficiary collects ODSP or not, it can lead to the preparation of a Will that includes no planning to structure the gift properly-to protect the recipient's qualification for ODSP benefits. When that happens, the recipient (or, if they are incapable, their legally appointed representative) must consider whether there are ways to protect the intended beneficiary’s qualification. The ODSP $40,000 asset limit applies to non-exempt property and funds. However, certain exempt assets are not counted when determining ODSP eligibility. If an inheritance is not planned properly, a recipient who wants to remain eligible can consider whether enough of the inheritance can be transferred into exempt assets. This would mean that their non-exempt total stays within the allowable $40,000 limit. Examples of exempt assets under ODSP include: An interest in a principal residence One motor vehicle Funds held in a Registered Disability Savings Plan (RDSP) A trust created by the ODSP recipient using inherited funds, provided the trust capital does not exceed $100,000 A pre-paid funeral Household goods and furnishings required for the reasonable enjoyment of a home There are a number of planning tools available to skillful Wills practitioners to assist in protecting a beneficiary’s entitlement to ODSP - a prime example is a Henson Trust. If you are preparing your Will and you have a family member collecting ODSP benefits, getting good advice early is crucial. - Ian Keay

Ontario’s Will validation rules are meant to prevent unfair outcomes where a person clearly intended a document to be their final Will, but the signing formalities weren’t perfect. However, there are limits — especially when the only “Will” is an unsigned draft that exists as a digital document only. A recent Ontario case, Madhani v. Fast, 2025 ONSC 4100, is a reminder that an unsigned electronic draft generally cannot be validated under Ontario law. The common scenario: lawyer takes instructions to draft a Will for Client lawyer prepares draft Will a signing appointment is booked the client dies before the Will is signed Will was not printed out - it exists in digital form only In Madhani , the draft Will was never printed and never executed. The draft existed only as an electronic file. Can the Court “validate” the draft anyway? Ontario’s validating provision is found at Section 21.1 of the Succession Law Reform Act (“ SLRA ”). Section 21.1 allows the Court to validate a document that does not comply with execution formalities provided it reflects the deceased’s testamentary intentions. In Madhani , the Court held Section 21.1 cannot be used to validate a Will that exists only in electronic form. Why not? Another piece of Ontario legislation, the Electronic Commerce Act, 2000 (“ ECA ”) explicitly limits the Court’s validating power. Section 31 of the ECA excludes Wills from electronic recognition. Section 21.1(2) of the SLRA explicitly makes Will validation subject to the exclusion under Section 31 of the ECA. In short: Ontario law still requires a physical testamentary document for validation to even be possible. Testamentary intention still matters Nevermind the “electronic draft” problem, which is significant on its own. There must also be evidence before the Court that supports that the digital draft was a valid reflection of the deceased Client’s fixed and final intention. Did the Client read the final draft? Did the Client sign the final draft? What evidence can be produced that shows what was drafted is an accurate reflection of the Client's "fixed and final intention"? Ontario courts often use the “deliberate, fixed and final intention” test drawn from George v. Daily, 1997 CanLII 17825 (MB CA). In Madhani , the draft Will was to be reviewed and confirmed at the signing meeting — only the signing meeting never happened – which means no evidence could be produced to decide whether the draft Will reflected the deceased Client’s fixed and final intention. The Court was not reasonably satisfied in Madhani . How this differs from other validation cases Ontario courts have validated Wills with execution defects where the document was physical and clearly authentic, for example: Cruz v. Public Guardian and Trustee , 2023 ONSC 3629 Vojska v. Ostrowski , 2023 ONSC 3894 But those cases involved paper documents that were physically present and clearly connected to the deceased’s fixed and final intention. Practical takeaways The Madhani case is a caution for both lawyers and families: print important drafts (especially when a signing meeting is imminent) try to obtain direct confirmation from the client (not only through intermediaries) digital drafts on devices may not be legally usable as Wills in Ontario Bottom line Madhani confirms that Ontario’s Will validation paradigm under Section 21.1 SLRA is helpful — but it is not a workaround for electronic-only drafts. Until legislation changes, a Will must exist in physical form before Ontario’s courts can consider validating the unsigned draft under SLRA s. 21.1.
