Choosing the wrong ownership structure for your home or investments can cost your beneficiaries tens of thousands of dollars in probate fees, taxes, or legal disputes.
Joint tenancy vs tenants in common: key differences
| Feature | Joint tenancy | Tenants in common |
|---|---|---|
| Right of survivorship | Yes — auto-transfer to survivor | No — share goes through estate |
| Share proportions | Must be equal in most provinces | Can be unequal (40/60, 25/75, etc.) |
| Governed by will | No — survivorship overrides will | Yes — share distributed per will |
| Probate on death | No | Yes — share enters estate |
| Creditor exposure during lifetime | Both owner’s interests exposed | Only each owner’s own share |
| Can be severed unilaterally | Yes | N/A — already separate shares |
| Common for spouses | Yes, very common | Sometimes used in second marriages |
| Common for investment partners | Less common | Yes — proportional ownership |
Probate savings from joint tenancy (Ontario example)
| Property value | Without joint tenancy (probate) | With joint tenancy (no probate) | Savings |
|---|---|---|---|
| $600,000 home | $8,250 | $0 | $8,250 |
| $800,000 home | $11,250 | $0 | $11,250 |
| $1,200,000 home | $17,250 | $0 | $17,250 |
Formula: (value − $50,000) × 1.5% Ontario estate admin tax.
Risks of adding an adult child to property title
| Risk | Likelihood | Mitigation |
|---|---|---|
| Capital gains triggered on transfer | Moderate-high | Legal advice on ACB tracking and principal residence exemption |
| Child’s creditors can claim their share | Low to moderate | Consider whether child has business/personal liability risk |
| Child’s divorce includes property as family asset | Low | Consider tenancy in common with clear ownership documentation |
| Child refuses to sign on future sale | Low but possible | Relationship risk — choose a trusted person |
| Resulting trust finding (property back to estate) | Moderate | Document intent in writing at time of transfer |
Converting from tenants in common to joint tenancy
Used when: spouses bought originally as tenants in common and wish to add survivorship protection for estate planning.
Steps:
- Consult a real estate lawyer — a transfer/transmittal deed is required
- Register the change at the provincial land registry
- Typically costs $1,000–$2,500 in legal and registration fees
- Update property insurance to reflect the ownership change
- No capital gains triggered when spouses transfer between themselves (spousal rollover applies)
Which structure is right for you?
| Situation | Recommended structure |
|---|---|
| Married couple buying principal residence | Joint tenancy — simple, auto-transfers on death |
| Common-law couple, unequal contributions | Tenants in common — document the ownership split |
| Parent and adult child buying together | Tenants in common — preserves parent’’s share for estate |
| Business partners buying investment property | Tenants in common — each party controls their share |
| Siblings inheriting cottage together | Tenants in common — allows independent estate planning |
| Blended family (second marriage) | Tenants in common — protects children from first marriage |
Tax implications of each structure
Joint tenancy — on death: The surviving joint tenant inherits the full property by right of survivorship. In Canada, a deemed disposition occurs at the time of death. The deceased’’s share is valued at fair market value, and any capital gain (minus the principal residence exemption if eligible) is reported on the deceased’’s final T1 return.
Tenants in common — on death: The deceased’’s share passes according to their will (or intestacy rules). The estate must go through probate for the property share. Probate fees apply on the value of the deceased’’s share. The surviving owner retains only their own proportional interest.
Frequently asked questions
Can joint tenancy be changed to tenants in common? Yes. Either joint tenant can sever the joint tenancy unilaterally in most provinces by registering a document (a severance) at the land titles office. In Ontario, this is done by registering a Transfer to Sever Joint Tenancy. No consent from the other co-owner is required in most provinces.
Does joint tenancy avoid probate in Canada? Yes — the right of survivorship means the property passes directly to the surviving owner without going through the deceased’’s estate. This avoids probate fees on that property. However, at the death of the last surviving joint tenant, the property does form part of the estate.
Can a joint tenant sell their share without the other owner’’s consent? No. Joint tenants cannot sell their share independently — the entire property must be sold with both owners’’ agreement. Tenants in common, however, can sell their individual share (or force a court-ordered partition if co-owners disagree).
Probate fees by province and impact on each structure
Because joint tenancy bypasses the estate, the property value is excluded from probate calculations. For tenants in common, the deceased’’s share is included in the estate and subject to provincial probate fees:
| Province | Probate fee rate | On $500,000 share |
|---|---|---|
| Ontario | ~1.5% | ~$7,500 |
| BC | ~1.4% (over $50,000) | ~$7,000 |
| Alberta | Max $525 flat | ~$525 |
| Quebec | Notarial wills exempt | $0 |
| Nova Scotia | ~1.7% | ~$8,500 |
For a $1M investment property held as tenants in common between two siblings, each sibling’’s 50% share ($500,000) would trigger approximately $7,500 in Ontario probate fees on death. Joint tenancy avoids this entirely — but only if the co-owners survive each other.
Common mistakes with property ownership in Canada
Mistake 1: Assuming marriage means joint tenancy Property is not automatically joint tenancy just because you are married. The title must explicitly state “joint tenants.” Many married couples hold property as tenants in common without realizing it.
Mistake 2: Adding an adult child to title for probate avoidance Adding a child to your home title as a joint tenant can backfire: it may trigger land transfer tax, a deemed disposition at fair market value, and the child’’s creditors could claim against the property. A better alternative is a power of attorney.
Mistake 3: Not updating after divorce In most provinces, divorce does not automatically sever joint tenancy. A separated spouse may still receive the property by right of survivorship. Legal advice is needed to sever joint tenancy after separation.
