Key takeaways
  • A second mortgage is registered like a first one and ranks behind it because the first has the earlier serial number.
  • Registration order, not the date you sign, decides who ranks first.
  • If payments are missed, a lender's recovery is generally limited to the land, though corporate borrowers and insured high-ratio first mortgages are exceptions.

You may be thinking about borrowing against the equity in your home without touching your existing mortgage. A second mortgage is one way people do that, but it sits behind the first lender, and that ranking shapes the cost, the risk and how easily it can be arranged.

This article explains in plain terms how a second mortgage is registered in Alberta, how its priority works, what the registration levy looks like and what can happen if you fall behind. It is general information, not advice on your own file.

This article covers the law of Alberta.

What a second mortgage is in Alberta

Under the Land Titles Act, a mortgage is a charge on land created merely to secure a debt or loan. A second mortgage is simply another mortgage registered against the same land while the first one is still there.

A registered mortgage works as security only. It does not transfer the land, so you remain the registered owner. To register one, the borrower signs a mortgage in the prescribed form or to the like effect.

How a second mortgage is registered

A second mortgage is registered the same way as a first mortgage and carries its own levy. Documents go to a Land Titles office on the prescribed form, by mail or drop-off, and fees are required when you submit. The alberta.ca page notes that in-person service was paused in Edmonton and Calgary, so confirm your options by phone.

Some lenders use a standard form mortgage. The lender files its standard terms with the Registrar, and a mortgage registered using them must say it consists of those terms, set out the principal sum, and be dated and signed by the borrower.

Once accepted, the document is recorded in the Alberta Land Titles Automation (ALTA) database with a registration number, and the submitter receives a registration notice.

How priority works behind the first lender

The Registrar gives an instrument a serial number only after the request is examined and found complete and in proper form. Priority between mortgagees is decided by that serial number. Instruments on the same land rank by registration, not according to the date they were signed.

That is why a second mortgage ranks behind the first: the first has the earlier serial number. A registered mortgage also keeps its priority for the advances and obligations it secures, including advances made after another instrument is registered. A revolving line of credit up to a stated principal sum has the same feature.

Rankings can be changed by agreement. A person entitled to a registered mortgage can postpone their rights by filing a postponement in the prescribed form, which puts those rights behind the others as if registered later. This is how a first mortgagee can agree to rank behind a later lender, or the reverse.

What registration costs

The mortgage levy payable to the Registrar is $50 plus $5 for each $5,000 or portion of the principal secured. The levy grows with the principal secured, so a larger second mortgage means a higher levy. For submissions received on or after October 20, 2024, the rate rose from $1.50 to $5 per $5,000.

What happens if payments are missed

In a mortgage enforcement action, a lender's right is generally restricted to the mortgaged land, and a borrower cannot waive that protection. On a foreclosure order, the default redemption period is six months for land other than farm land and one year for farm land.

There are exceptions. Those protections do not apply to mortgages given by corporations. They also do not apply to a high-ratio mortgage as defined in the regulations, so they may not help a borrower on an insured high-ratio first mortgage. Whether your situation falls into an exception depends on the facts.

Interest terms also matter. No fine, penalty or higher interest rate may be taken on arrears of principal if it raises the charge above the rate on principal not in arrears. Charging interest at an annual rate above 35 per cent is a criminal offence, and interest includes all charges and expenses for advancing credit.

What to do next

Frequently asked questions

Why does a second mortgage rank behind the first?

Priority is set by the serial number the Registrar assigns, and the first mortgage has the earlier one. Registration order, not the signing date, decides the ranking.

Can a second mortgage ever rank ahead of the first?

Only by agreement. A mortgagee can file a postponement that puts its rights behind another instrument as if registered after it.

How much is the registration levy on a second mortgage?

It is $50 plus $5 for each $5,000 or portion of the principal secured. A reduced levy can apply only in limited cases, such as when the same lender's new mortgage supplements, is collateral to, substitutes for or partially replaces its existing mortgage against one condominium unit.

Can a second mortgage lender sue me personally if I default?

Generally the lender's right in an enforcement action is restricted to the mortgaged land. That protection does not apply to corporate borrowers or high-ratio mortgages as defined in the regulations, so a lawyer should confirm your position.
