Sold an Ontario Rental at a Loss? The Tax Rules Treat the Land and the Building as Two Separate Losses

The price on your closing statement is really two numbers — land and building — and when you sell at a loss the Income Tax Act sends each one down a different track. One half can become a usable capital loss; the other was never a capital loss at all.

I’m Arthur Zhao, a Toronto real estate broker. Look at the closing statement from the day you bought your rental and you will see a single purchase price. The tax system does not. To the Income Tax Act that one number is really two — the price of the land and the price of the building that sits on it — and when you later sell at a loss, those two numbers go their separate ways. A loss on the building is handled under one regime; a loss on the land under another; and the same sale can produce a usable loss on one part and nothing at all on the other. Before you can ask whether your loss is deductible, you have to split it in two. Here is how each half is treated, and what quietly zeroes each of them out.

One Price, Two Assets

Start with the thing that makes this confusing: you never really bought a “property” as a single item. You bought land, and you bought whatever was built on it, and for tax purposes those are two different kinds of asset with two different life stories.

The building is depreciable property — over the years you owned it, the capital cost allowance system let you treat part of its cost as an expense. The land is not depreciable; it just sits there as capital property. That single distinction — depreciable versus not — is what sends a loss on each part down a different track. It is also why the allocation of your purchase price between land and building — the split your appraisal or your closing documents assigned — quietly controls how much of your loss is even eligible to be a loss.

The Building and the Land: Two Different Tracks

The Building Part: A Loss That Was Never a Capital Loss

Here is the first surprise. A loss on the building is not a capital loss at all. s.39(1)(b)(i) takes losses on depreciable property out of the capital-loss definition. Instead, the building sits in the capital cost allowance (CCA) system. Under s.20(16), if at the end of the year you no longer own any property of that CCA class and undepreciated cost remains, the excess is deducted as a terminal loss — a CCA-system deduction, not a capital loss.

That matters because a terminal loss and a capital loss behave very differently — but the detail of how a terminal loss is calculated is a conversation for your accountant. What you should know at the planning stage is the trap: s.13(21.2), titled “Loss on certain transfers,” tests the situation on the 30th day after the sale. If, on that day, you (or a person affiliated with you) still own the building or have a right to reacquire it, the rule limits the loss the seller can take. It is built to stop a loss from being crystallized while the same economic group keeps the asset. The mechanics are technical; the principle is simple: selling the building to someone in your own circle does not hand you a clean loss.

The Land Part: A Real Capital Loss — Until Something Zeroes It Out

The land is where an actual capital loss can live. But two situations reduce even that to nil.

One — you were really using it yourself. If the property was personal-use property — a home or a vacation place used primarily by you or certain family members rather than held as a true investment — s.40(2)(g)(iii) makes the loss nil. The tax system simply does not recognize a capital loss on personal-use property; the definition of that term sits in s.54.

Two — you sold to someone in your own circle who still holds it. Under s.54, a loss is a superficial loss if, within the window that runs from 30 days before the sale to 30 days after it, you or a person affiliated with you acquires the same — or an identical — property, and still owns it (or has a right to acquire it) at the end of that window. When that happens, s.40(2)(g)(i) makes the loss nil.

The loss is not simply erased, though. s.53(1)(f) takes the denied superficial loss and adds it to the cost base of the property in the hands of the person who acquired it — so it rides along on that asset until they eventually sell.

When the Buyer Is Your Spouse, a Different Rule Comes First

There is a wrinkle that sits on top of everything above, and it changes the order of the analysis whenever the buyer is your spouse or common-law partner. Before you ever reach the superficial-loss rules, s.73(1) steps in. When an individual transfers capital property to a spouse or common-law partner and both are resident in Canada, the property is deemed by default to be disposed of at the transferor’s own cost — the adjusted cost base for non-depreciable property such as land, and a proportionate share of the un-depreciated capital cost for the building (s.73(1.01)).

Read that again: at the default setting, no loss is realized at all, whatever price appears on the transfer, because you are treated as selling at your own cost. A superficial loss only enters the picture if you actively elect out of this rollover in your tax return for the year — and only then do s.54, s.40(2)(g)(i), and, for the building, s.13(21.2) do their work.

One boundary worth flagging: this spousal rollover is specific to a spouse or common-law partner. A sale to a company you control is not a s.73 transfer, so there is no automatic roll-to-cost there; the affiliated-person and superficial-loss analysis applies to that sale directly.

The Price on the Contract: Selling Cheap to Someone Close

Cutting across both the land and the building is a question about the price itself. If you sell — or give — the property to someone you are not dealing with at arm’s length for less than its fair market value, s.69(1)(b) deems your proceeds to equal that fair market value anyway. Setting a low price on a family sale does not manufacture a bigger loss; the result is calculated as if you had sold at market.

This is also where an assumption about “selling to the kids” needs a boundary line. The affiliated-person test that drives the superficial-loss rules is narrow: under s.251.1(1)(a) an individual is affiliated with a spouse or common-law partner, and under s.251.1(1)(b) with a corporation that the person (or their spouse) controls — but that provision does not list children, parents, or siblings. A sale to an adult child, then, is generally not caught by the superficial-loss rule. That is a separate question from whether the sale is at arm’s length for s.69, which turns on the facts of the dealing — so a below-market sale to a child can still be pulled up to fair market value even where the superficial-loss rule never applies.
