- Ontario land transfer tax applies to conveyances of land — transfers of ownership — not simply to registering a new mortgage or discharging an old one on a property you already own.
- A mortgage is a security interest registered against your title — it gives your lender a claim against the property if you default, but it doesn't transfer ownership of the property itself.
- The straightforward case above assumes ownership stays exactly the same.
Homeowners renewing or refinancing their mortgage sometimes worry they're about to trigger the same land transfer tax bill they paid when they first bought the property. It's a reasonable question to ask before signing anything — and for most straightforward refinances, the concern isn't warranted. But "usually not" isn't the same as "never," and knowing where the line sits matters.
Short Answer: Usually No
Ontario land transfer tax applies to conveyances of land — transfers of ownership — not simply to registering a new mortgage or discharging an old one on a property you already own. A straightforward refinance, where you keep the same ownership and simply change or increase your financing, typically doesn't involve a conveyance at all, and so typically falls outside land transfer tax's scope.
Why Mortgages Aren't Treated as "Conveyances"
A mortgage is a security interest registered against your title — it gives your lender a claim against the property if you default, but it doesn't transfer ownership of the property itself. Discharging an existing mortgage and registering a new one are standard, routine registration mechanics, distinct from transferring the property to someone else. Since Ontario's land transfer tax is triggered by a conveyance of land (or certain unregistered transfers of a beneficial interest in land), and a refinance-only transaction doesn't change who owns the property, it generally doesn't trigger the tax.
When Refinancing COULD Raise Land Transfer Tax Questions
The straightforward case above assumes ownership stays exactly the same. Refinancing situations that also involve a change in who's on title are different, and worth flagging before you proceed:
- Adding someone to title — a spouse, family member, or anyone else — as part of restructuring your financing
- Removing someone from title, for example after a relationship change
- Moving the property into or out of a trust or corporation as part of a broader restructuring
- Any refinance bundled with a separate transaction that itself involves a transfer of an interest in the property
Because land transfer tax is calculated on the value of the consideration for a transfer, whether any of these situations actually creates a tax bill — and how much — depends on the specific facts: what's being transferred, whether any consideration (including assumed mortgage debt) changes hands, and whether an exemption might apply. This is genuinely fact-specific, and not something to assume your way through.
A Straightforward Refinance: What Actually Happens
In an ordinary refinance with no change in ownership, your existing mortgage may be discharged and a new one registered, or your existing lender may register an increase or renewal directly. These are standard closing mechanics, typically coordinated by a lawyer, and they don't involve registering a transfer of the property itself — which is why they generally sit outside land transfer tax altogether.
Questions to Ask Before You Refinance
- [ ] Is anyone being added to or removed from title as part of this refinance?
- [ ] Is the property moving into or out of a trust, corporation, or other ownership structure?
- [ ] Has your lender or lawyer flagged any land transfer tax considerations specific to your situation?
- [ ] Have you confirmed the current rules with a lawyer if your refinance is anything other than a straightforward renewal or increase with no change in ownership?
Frequently asked questions
Does switching lenders at renewal trigger land transfer tax?
No, on its own — switching lenders while keeping the same ownership is a financing change, not a conveyance of land, so it doesn't trigger land transfer tax by itself.
What about adding my spouse to title as part of a refinance?
It depends on how the addition is structured and whether any consideration — including assumed mortgage debt — changes hands as part of it. Because land transfer tax is calculated on the value of the consideration, a straightforward addition with little or no consideration involved may result in little or no tax, but the details genuinely matter here — confirm with a lawyer before you proceed rather than assuming either way.
Do I need a lawyer just to refinance my mortgage?
Not always — many straightforward renewals and refinances are handled directly through your lender. But anything involving a change to who's on title benefits from a lawyer's review, both for the land transfer tax question and to make sure the registration itself is done correctly.
Will my lender flag it if land transfer tax applies?
Not necessarily — lenders are focused on the mortgage transaction itself, not on assessing your land transfer tax exposure. That gap is exactly why it's worth a quick legal check before a refinance that involves anything beyond a straightforward renewal.
