Subject-To Deals in Alberta: Are They Legal and Smart?

 

Scroll through real estate investing content for five minutes and someone will tell you about "subject-to" deals. Take over a seller's mortgage, skip the bank, buy with little money down, and collect cash flow. It's a strategy built largely on American law and American mortgages, and it gets repeated in Canada as if it works the same way here. When it comes to subject to real estate Canada investors need to be far more careful.

In a subject-to deal, the buyer takes ownership while the seller's existing mortgage stays in place, in the seller's name. In some situations, with full disclosure, lender involvement, and proper legal advice, variations of this can be done. But the typical online version runs straight into Canadian mortgage terms, Alberta law, and real risks for both buyer and seller.

This guide explains how subject-to deals work, why they're different in Alberta, what a recent Alberta court decision tells us, and the safer alternatives. For the wider strategy picture, see our guide to investment real estate in Edmonton.

 

How a Subject-To Deal Works

In the classic version:

•        The seller transfers title to the buyer.

•        The seller's mortgage stays registered against the property, in the seller's name.

•        The buyer makes the mortgage payments, often while renting out the property.

•        The lender may not be told, which is where the trouble starts.

The appeal is obvious: the buyer avoids qualifying for a new mortgage and may inherit a lower interest rate. The seller gets out from under payments they can't afford. But both sides take on risks that the online pitch rarely mentions.

Why Subject To Real Estate in Canada Is Different

Canadian mortgage terms

Most Canadian residential mortgages include terms that restrict selling or transferring the property without the lender's consent. If the lender learns of a transfer, it may be able to demand full repayment. Canadian mortgages also usually renew every few years, so a buyer relying on a seller's mortgage faces a renewal in the seller's name, which the seller has to cooperate with and qualify for.

Alberta's deficiency rules cut both ways

Alberta has an unusual protection. Under section 40 of the Law of Property Act, lenders generally can't sue individual borrowers for a shortfall after foreclosure on a conventional residential mortgage. They're limited to the land.

But that protection doesn't apply to CMHC-insured and other high-ratio mortgages. A University of Calgary law faculty analysis of assuming high-ratio mortgages in Alberta describes how, in CIBC Mortgages Inc v Abdallah, 2015 ABQB 363, a buyer who assumed a mortgage was held personally liable because it had been high-ratio when it was first given. The court called it a "trap for the unwary."

Mortgage type	Lender can sue individual for shortfall?	Why it matters in a subject-to deal
Conventional, uninsured	Generally no, limited to the land	Seller still faces credit damage from default
CMHC or privately insured high-ratio	Yes	Seller, and possibly an assuming buyer, can be personally liable

 

A 2026 Alberta decision on "assuming" mortgages

In Moran v. 1715664 Alberta Inc., 2026 ABKB 50, owners of ten Lethbridge condos transferred title to a company for $1, with the company to "assume" the mortgages. The company made payments while the original owners stayed on the loans and kept renewing them for years. The Court of King's Bench found the deal required the buyer to actually replace the sellers as borrowers, not just make payments, and ordered it to do so within 30 days or sell the units and pay out the mortgages.

The takeaway: courts recognize that leaving sellers exposed on mortgages they no longer control is a real harm.

The Risks for Sellers

•        You remain on the mortgage. If the buyer stops paying, it's your credit and possibly your liability.

•        You may struggle to qualify for your next home because the old mortgage still shows as your debt.

•        Insurance problems. If you no longer own or live in the home, the existing insurance may not respond properly.

•        Renewals. You may have to renew a mortgage on a home you don't own.

If you're behind on payments and someone has offered to "take over your mortgage," talk to a lawyer first. There may be better ways to protect your equity and credit.

The Risks for Buyers

•        The lender can call the loan. If that happens, you need to refinance immediately or risk losing the property.

•        You don't control the mortgage. The seller could refinance, default on other debts, or face a claim that affects the property.

•        Possible personal liability on high-ratio mortgages.

•        Reputation and regulatory risk. Deals that rely on hiding information from lenders can cross into misrepresentation. Licensed agents face additional professional obligations.

Safer Alternatives to Subject-To

Strategy	How it works	Key advantage
Formal mortgage assumption	Buyer applies to the lender to take over the mortgage	Lender consents and the seller can be released
Vendor take-back mortgage	Seller lends part of the price, registered as a mortgage	Transparent and enforceable
Rent-to-own	Tenant rents with an option to buy later	Gives time to build down payment or credit
Joint venture	Investor partners with a homeowner or another investor	Shared risk with clear written terms

If You're Considering a Subject-To Structure

•        Get independent legal advice for both buyer and seller. Our guide to real estate lawyer fees in Edmonton shows what to budget.

•        Read the mortgage terms for any transfer restrictions.

•        Find out whether the mortgage was high-ratio when it was first given.

•        Talk to the lender about a formal assumption.

•        Put everything in writing, including what happens at renewal, default, or sale.

•        Avoid any arrangement that depends on concealing information from a lender or insurer.

 

Choose Structures That Survive Daylight

The best creative financing deals are ones you'd be comfortable explaining to the lender, the court, and your own family. If a structure only works because someone doesn't know about it, it's not a strategy. It's a risk. Start with transparent tools, get independent legal advice for both sides, and build a portfolio that lasts. This article is general information, not legal advice.
