Mortgage Default

Definition

Mortgage default occurs when a borrower fails to meet the terms of the mortgage agreement — most commonly by missing scheduled payments — giving the lender the right to pursue remedies set out in the mortgage and provincial law.

What actually counts as a default, and what happens next?

Missed or late payments are the most common trigger, but a mortgage can also go into default for other breaches of the agreement, such as letting property taxes or insurance lapse. Once a borrower falls behind, the account is typically reported as being in arrears before more serious remedies begin.

What a lender can do next depends heavily on the province, because mortgage enforcement is governed by provincial law, not one national process. In some provinces the typical route is power of sale; in others it is judicial foreclosure. Lenders generally prefer to work out a solution — a repayment plan, a deferral, or a refinance — before pursuing either remedy, since enforcement is costly and slow for everyone involved.

How it’s used in Canada

Provincial, not national: the legal process that follows a default — power of sale versus judicial foreclosure — is set by provincial law and varies across Canada.

Early contact matters: lenders typically prefer borrowers reach out as soon as payments become difficult, since early options are usually broader than options available once a file is deep in arrears.

Insured mortgages involve the insurer: on a default-insured mortgage, CMHC, Sagen, or Canada Guaranty may become involved once a lender pursues a claim, alongside the lender’s own recovery process.

Broker’s role stops at origination: mortgage agents, submortgage brokers, mortgage associates, and courtiers hypothécaires arrange financing but are not the party managing default and enforcement — that is handled directly between borrower and lender, often through legal counsel.
