The client
A Midland couple separating after years in a $512,000 matrimonial home, with the keeping spouse buying out the departing spouse's interest for $235,000 under a written separation agreement, financed by a refinance in the keeping spouse's sole name.

What almost got charged
$2,075 in land transfer tax on the transfer
The problem
Registering the transfer of the departing spouse's interest looked, on its face, like an ordinary conveyance — and the file was initially set up to calculate and remit land transfer tax on that basis. Ontario's Land Transfer Tax Act taxes transfers of an interest in land by default; it does not automatically know or apply a family-law exemption on its own.
The exemption the file almost missed
- ▸Ontario Regulation 70/91, made under the Land Transfer Tax Act, exempts a matrimonial-home transfer between spouses made in compliance with a written separation agreement or court order
- ▸The exemption is never automatic — it has to be properly claimed on the registration itself
- ▸Without it, the transfer would have been taxed exactly like an ordinary purchase
Nothing about the couple's own facts was in question; the separation agreement was in writing and the transfer matched it exactly. The tax question was purely about whether the exemption got claimed.
The numbers
Confirming the exemption applied was worth more, in dollar terms, than anything else in this file's math.
| The buyout | Amount |
|---|---|
| Buyout payout to the departing spouse | $235,000 |
| Land transfer tax if taxed as an ordinary transfer | $2,075 |
| Land transfer tax actually paid, under the O. Reg. 70/91 exemption | $0 |
| Total debt service | Figure |
|---|---|
| Payment at the qualifying rate (6.90%), 25 years | $1,631/mo |
| Property tax | $305/mo |
| Heat (lender estimate) | $125/mo |
| Car loan | $260/mo |
| Total debt service, keeping spouse's income alone | 29.4% |
29.4% comfortably clears on the keeping spouse's own income, well before the tax question ever came into it. See the full land transfer tax rules across Canada for how family-law exemptions compare province to province.
The solution
A mortgage agent licensed under Ontario's Mortgage Brokerages, Lenders and Administrators Act flagged the tax question to the couple's real estate lawyer before the transfer was registered, rather than after a tax bill arrived.
First, confirmed the transfer's own paperwork matched the separation agreement. The buyout amount, the parties, and the property all lined up exactly with what the written agreement set out.
Second, confirmed Ontario Regulation 70/91's exemption applied. A matrimonial-home transfer between spouses made in compliance with a written separation agreement is exempt from land transfer tax under the Act's own exemptions regulation.
Third, made sure the exemption was actually claimed on registration. The exemption does nothing on its own if the transfer is registered as though it were an ordinary conveyance.
The outcome
The buyout refinance funded at 4.90%, with total debt service at 29.4% on the keeping spouse's income alone, and no land transfer tax paid on a transfer that Ontario's own regulation exempts.
This is an uninsured buyout refinance, so the 29.4% TDS figure is informational, not a CMHC ceiling.
What to take from this file
- 01Land transfer tax exemptions are never automatic. Ontario Regulation 70/91's spousal exemption has to be claimed on the registration itself, not assumed to apply.
- 02A written separation agreement is the key document. The exemption turns on the transfer being made in compliance with one, not simply on the parties being spouses.
- 03The exemption's dollar value can be real money. On this file it was worth more than the buyout's own qualifying-payment math.
- 04Flag the tax question to the real estate lawyer before registration, not after. Once a transfer registers as an ordinary conveyance, unwinding the tax treatment is far harder than claiming it correctly the first time.

Illustrative in this file — lender-specific, not rules:
- ▸4.90% contract rate — rates move daily; not a quote.
- ▸the avoided land-transfer-tax figure — shown using the buyout amount as the illustrative tax base; the exact basis for calculating land transfer tax on a partial-interest spousal transfer depends on the conveyance's own structure, so this demonstrates the exemption's value, not a tax opinion.
- ▸the TDS figure — this is an uninsured buyout refinance, so there is no CMHC ratio ceiling — the number is informational.
