Joint Tenancy vs. Tenants in Common in Ontario (2026): How Title Affects Your Mississauga Home & LTT Rebate
2026 Ontario Property Title & Land Transfer Tax Advisory by Fernando Borges Mora, REALTOR® (eXp Realty) — Co-Signing Parents, 99%/1% Tenants in Common & Probate Protection.
The Decision Every Mississauga Co-Buyer Makes With Their Lawyer Before Closing
In 2026, over 35% of First-Time Home Buyers in Mississauga purchase property alongside a spouse, a sibling, a business partner, or a parent co-signing the mortgage to pass the federal mortgage stress test.
When two or more people are registered on the Transfer/Deed of Land in Ontario's Teranet land registration system, Ontario property law requires you to elect one of two forms of co-ownership:
- Joint Tenancy (With Right of Survivorship)
- Tenants in Common (Defined Percentage Shares, e.g., 50%/50% or 99%/1%)
Led by Fernando Borges Mora, licensed Ontario REALTOR® with eXp Realty, this guide explains how each structure works under Ontario law—and how the Ontario Ministry of Finance calculates your $4,000 First-Time Homebuyer Land Transfer Tax Refund when a parent goes on title.

Side-by-Side Comparison: Joint Tenancy vs. Tenants in Common in Ontario
| Legal & Financial Feature | Joint Tenancy (Right of Survivorship) | Tenants in Common (Percentage Shares) |
|---|---|---|
| Ownership Share Structure | All owners hold an equal, undivided 100% interest together (cannot be split 99% / 1%). | Owners can hold equal (50/50) or unequal shares (e.g., 99% Child / 1% Parent, or 70/30). |
| What Happens Upon Death of One Owner? | Right of Survivorship: Title automatically passes to the surviving joint owner(s) outside of the deceased's Will, bypassing Ontario's 1.5% Estate Administration Tax (Probate). | No Right of Survivorship: The deceased owner's percentage share passes to their beneficiaries according to their Will (and goes through Estate Probate). |
| Best Used By Whom? | Married or Common-Law Couples purchasing a shared family home where both want the surviving spouse to inherit 100% automatically. | Parents Co-Signing for a First-Time Buyer Child (99%/1%), siblings buying together, unmarried co-investors, or blended families. |
| Impact on $4,000 Ontario LTT Rebate When Co-Buying With a Non-First-Time Buyer Parent | Severe Penalty: Because ownership is deemed 50%/50%, the first-time buyer child loses 50% of their LTT rebate (loses $2,000). | Protects 99% of Rebate: By registering 99% First-Time Buyer Child / 1% Parent, the child keeps 99% of the $4,000 rebate ($3,960)! |
The $2,000 Trap: How Parents Co-Signing a Mississauga Mortgage Should Register Title
Here is the exact scenario that happens every week in Mississauga:
- A first-time buyer is purchasing a $600,000 Square One condo, where the Ontario Land Transfer Tax is $8,475.
- Because the buyer has never owned a home anywhere in the world, they qualify for the maximum $4,000 Ontario First-Time Homebuyer LTT Rebate.
- However, to qualify for the mortgage with an A-lender, the bank requires one of their parents (who already owns a house in Mississauga) to be added as a co-borrower and co-owner on title.
Under Section 9.2 of the Ontario Land Transfer Tax Act, the $4,000 first-time buyer refund is reduced proportionally by the ownership share of any co-buyer who is not a first-time home buyer (unless the co-buyer is your legal/common-law spouse):
- Mistake #1 — Taking Title as 50/50 Joint Tenants With Your Parent: Because Joint Tenants hold equal 50%/50% interests, the Ontario Ministry of Finance only grants the first-time buyer child 50% of the $4,000 refund ($2,000)—costing you $2,000 out of pocket on closing day.
- Solution #1 — Taking Title as Tenants in Common (99% Child / 1% Co-Signing Parent): Most Canadian major banks allow a co-signing parent to hold just a 1% Tenants in Common share on title while the first-time buyer child holds 99%. Under this structure, the child receives 99% of the maximum refund ($3,960 out of $4,000), losing only $40!
- Solution #2 — Parent as "Guarantor Only" (Off Title) or Bare Trustee: Even better, ask your mortgage broker if the lender will accept your parent strictly as a Covenantor / Guarantor (signing the mortgage guarantee without going on title at all) or via a Bare Trust Agreement where the child holds 100% beneficial ownership—preserving 100% of the $4,000 LTT Rebate and protecting the parent from capital gains complications on their 1% share.
