The problem
A newcomer to Canada, and to how Ontario condominiums are legally structured, assumed a parking space listed in the purchase agreement was simply part of the unit being bought. It is not always: under Ontario’s Condominium Act, 1998, a condominium parking space is frequently registered as its own separate unit, with its own PIN, a distinct piece of real property sold together with a residential unit rather than folded into that unit’s own legal description.
What a single-PIN closing would have missed
- ▸The residential unit and the parking space were registered years earlier as two separate condominium units, each with its own PIN
- ▸A transfer naming only the residential PIN would leave the parking unit’s ownership entirely unaddressed
- ▸A mortgage charge naming only the residential PIN would leave the parking unit unsecured, and financeable by no one
Nothing about the deal itself was unusual. The buyer simply had no way of knowing a condominium parking space could be its own separate unit — nobody had told them, and nothing in the listing said so.
The numbers
Financing the combined purchase across both PINs together turned out to be the easy part; getting both PINs onto the closing paperwork in the first place was the actual work.
| The insured purchase, financed across two PINs | Amount |
|---|---|
| Combined purchase price (both PINs) | $412,000 |
| Down payment (10%) | $41,200 |
| CMHC premium (3.10% at 90% LTV) | +$11,495 |
| Total insured mortgage | $382,295 |
| Ratio check at the qualifying rate | Figure |
|---|---|
| Payment at the qualifying rate (6.95%), 25 years | $2,666/mo |
| GDS (payment + $305 tax + $125 heat) ÷ $8,900 income | 34.8% |
| TDS (GDS numerator + $215 car loan) ÷ $8,900 income | 37.2% |
34.8% and 37.2% sit comfortably inside CMHC’s 39% GDS and 44% TDS maximums; the two-PIN registration changed nothing about the mortgage arithmetic itself, since the charge simply secures the same total loan across both units together — a routine ratio outcome consistent with first-time homebuyer statistics once the registration itself is sorted out.
The solution
A mortgage agent licensed under Ontario’s Mortgage Brokerages, Lenders and Administrators Act treated the parking space as what the land registry actually showed it to be, rather than what the listing implied it was.
First, confirmed directly with the land registry office which PIN carried the parking unit. A quick title search settled the question the agreement of purchase and sale had simply glossed over.
Second, had the real estate lawyer prepare a second transfer instrument alongside the first, so the parking unit’s ownership actually transferred to the buyer on closing, not just the residential unit’s.
Third, registered one mortgage charge naming both PINs together, so the lender’s security actually covered the parking unit the buyer believed they were financing all along.
The outcome
The purchase funded insured at 34.8% GDS and 37.2% TDS, with title and the mortgage charge correctly registered against both PINs.
Both ratios sit comfortably inside CMHC’s 39% GDS and 44% TDS maximums. Ontario’s land transfer tax on the $412,000 combined purchase came to $4,715.
What to take from this file
- 01A condominium parking space can be its own separately-titled unit, with its own PIN. Never assume it is folded into the residential unit’s own legal description just because the listing sold them together.
- 02Confirm PINs directly with the land registry, not from the listing or the agreement of purchase and sale alone. Those documents describe the deal; they do not always describe the title structure underneath it.
- 03A multi-PIN condominium purchase needs a transfer for each PIN and a mortgage charge naming all of them. Missing one leaves that piece of property unaddressed on closing.
- 04This is a registration-mechanics problem, not a financing problem. Once both PINs are identified, the mortgage math itself is no different from any other insured purchase.
