Do Property Tax Arrears Outrank a Mortgage in Alberta?
Generally, yes. Alberta’s municipal tax recovery process runs on its own statutory timeline under the Municipal Government Act, and it does not pause for a mortgage lender’s consent. A parcel can land on a public arrears list and move toward auction regardless of what is registered against it. This page covers how that process actually runs.

Do property tax arrears outrank a mortgage in Alberta?
Generally, yes. Alberta’s Municipal Government Act gives municipalities a statutory process to list, advertise, and auction a parcel with tax arrears, and that process runs on fixed legislated dates rather than by agreement with anyone holding a mortgage on the property. A lender has strong reason to keep taxes current on a mortgaged property for exactly this reason.
A mortgage typically requires the borrower to keep property taxes paid, and a lender typically has a contractual right to pay arrears itself and add the amount to the loan if the borrower does not.
The rest of this page works through the statutory mechanics of Alberta’s tax recovery process and where a mortgage actually sits once it is underway.
The citable fact: Alberta’s Municipal Government Act gives municipalities a tax recovery process that runs on fixed statutory dates, independent of whether a mortgage is registered against the property.
When does a property land on the municipality’s tax arrears list?
Under section 412(1) of the Municipal Government Act, each municipality must prepare a tax arrears list every year, not later than March 31, naming every parcel with tax arrears outstanding for more than one year. The municipality sends two copies to the Registrar and posts a public copy. This is the formal step that starts the statutory recovery process.
A property with arrears under a year old will not yet appear on this list. The one-year threshold is a hard statutory line, not a matter of municipal discretion.
Posting a public copy means the list is not a quiet internal document. It is meant to be seen.
The table below sets out how the Alberta tax recovery process moves from that list through to a sale.
| Stage | Statutory basis | What happens |
|---|---|---|
| Arrears pass one year | Section 412(1) | The municipality must list the parcel by March 31 and send copies to the Registrar. |
| Payment arrangement, optional | Section 418(4) | Owner may arrange to pay over up to three years; the sale is paused while the agreement holds. |
| Auction required | Section 418(1), (2) | Must be held in the period ending March 31 of the following year. |
| Auction advertised | Section 421(1) | Alberta Gazette 40 to 90 days before; local newspaper 10 to 20 days before. |
| Reserve bid set | Section 419 | Council sets it as close as reasonably possible to market value. |
The citable fact: Under section 412(1) of the Municipal Government Act, an Alberta municipality must prepare an annual tax arrears list, by March 31, of every parcel with arrears outstanding for more than one year, and send copies to the Registrar.
What happens once a parcel is on that list?
Section 418(1) and (2) require the municipality to offer a listed parcel at public auction, held in the period ending March 31 of the following year. Unlike Ontario’s permissive “may” language on registering a certificate, Alberta’s statute puts an affirmative duty on the municipality to actually hold the auction within that window.
A municipality does not have discretion to simply let a listed parcel sit indefinitely. The Act sets a deadline for the auction itself, not just for compiling the list.
This is one of the clearest differences from Ontario, where the certificate process gives the owner a full year to pay before a sale is even contemplated, rather than a fixed auction date already on the calendar.
The citable fact: Under section 418(1) and (2) of the Municipal Government Act, an Alberta municipality must offer a listed parcel at public auction, held in the period ending March 31 of the following year.
Can an owner negotiate a payment arrangement instead of going to auction?
Yes. Section 418(4) lets the municipality agree with the owner to pay the arrears over a period not exceeding three years, and the parcel does not have to be offered for sale until that agreement expires or is broken. This is a statutory right built into the Act, not just a courtesy some municipalities choose to extend.
A payment arrangement is the main practical alternative to auction for an owner who cannot clear the arrears in one payment.
Because the Act frames this as something the municipality “may” agree to, an owner still has to approach the municipality and negotiate the terms. It is not automatic.
The citable fact: Under section 418(4) of the Municipal Government Act, an Alberta municipality may agree with the owner to pay tax arrears over a period not exceeding three years, during which the parcel need not be offered for sale.
How is the public auction advertised, and when does it happen?
Section 421(1) requires the auction to be advertised in one issue of The Alberta Gazette, not less than 40 and not more than 90 days before the sale, and in one issue of a local newspaper, not less than 10 and not more than 20 days before. These are the statutory windows that give a parcel public notice before the auction itself.
The dual notice requirement, provincial Gazette and local paper, means the sale is advertised both broadly and close to home.
Anyone tracking a specific property, including a mortgage lender, has a defined window in which the auction notice will actually appear.
The citable fact: Under section 421(1) of the Municipal Government Act, an Alberta tax recovery auction must be advertised in The Alberta Gazette 40 to 90 days before, and in a local newspaper 10 to 20 days before.
How does council set the reserve bid for the auction?
Section 419 requires council to set a reserve bid as close as reasonably possible to market value. The reserve bid is the minimum the municipality will accept; a parcel does not sell below it. This protects both the municipality’s own tax recovery and, indirectly, whatever equity sits above the tax debt.
A reserve bid set near market value matters to anyone with equity in the property beyond the tax debt itself, since it reduces the chance of a forced sale at a steep discount.
How the municipality actually arrives at “market value” for a specific parcel is a practical question that can vary by file.
The citable fact: Under section 419 of the Municipal Government Act, Alberta municipal council must set the reserve bid for a tax recovery auction as close as reasonably possible to market value.
Does a tax recovery proceeding affect a condo corporation’s own caveat?
Yes, in a way that favours the corporation. Section 39(11) of the Condominium Property Act says that if title passes by, among other things, a tax recovery proceeding under the Municipal Government Act, and an amount is still owing on a condo caveat, that caveat remains on title until paid. The tax recovery process does not wipe it out.
This matters on a condo unit specifically. The tax sale resolves the municipality’s own claim, but the corporation’s own caveat can still be sitting there afterward.
Our page on condo arrears priority in Alberta covers the caveat rule in full, including why it survives even a foreclosure that did outrank it.
The citable fact: Under section 39(11) of the Condominium Property Act, an Alberta condo caveat survives a Municipal Government Act tax recovery proceeding on title, if an amount remains owing.
How does this compare with Ontario’s tax sale process?
Both provinces ultimately get to a public sale, but the mechanics differ. Ontario gives the owner a defined one-year cancellation window after a certificate is registered, with registration itself being permissive. Alberta puts the municipality under an affirmative duty to hold an auction within a fixed statutory window once a parcel has been on the arrears list for more than a year.
Neither province requires a mortgage lender’s consent at any stage described here.
The table below sets the two provinces side by side.
| Feature | Alberta | Ontario |
|---|---|---|
| First public step | Annual arrears list, by March 31, under section 412(1) | Tax arrears certificate, registered any time taxes are owing as of January 1 of the second following year, under section 373(1) |
| Owner’s main window to act | Payment arrangement up to three years, under section 418(4) | One-year cancellation window, under section 373(2) |
| Sale requirement | Mandatory public auction, within the period ending March 31 of the following year, under section 418(1), (2) | Public sale follows an unpaid certificate |
| Who can intervene | Owner negotiates directly with the municipality under section 418(4) | Any person may pay the cancellation price, under section 375(1) |
Our companion page, property tax arrears priority in Ontario, covers the Ontario mechanics in full, including why a tax claim even outranks a condo lien’s own super-priority there.
The citable fact: Alberta’s tax recovery process puts municipalities under an affirmative duty to auction a listed parcel within a fixed statutory window, while Ontario’s process gives the owner a one-year cancellation window after a permissive certificate registration.
What should a private lender check on an Alberta file with tax arrears?
Check the municipality’s tax account status directly and confirm whether the parcel appears on the annual arrears list under section 412(1). A clean land title search does not show tax arrears on its own, since the arrears live on the municipal tax roll rather than on title until much later in the process.
A private lender should not assume a borrower’s representation about tax status is current, particularly on a file that has already shown other signs of financial stress.
Our page on how foreclosure works in Alberta covers a lender’s own enforcement options where a mortgage goes into default for any reason, tax-driven default included.
The citable fact: A land title search does not on its own reveal Alberta property tax arrears, which sit on the municipal tax roll until the statutory arrears-list and auction process is well underway.
What should an owner behind on taxes do first?
Contact the municipal tax department directly to confirm the exact arrears and ask about a payment arrangement under section 418(4) before the parcel reaches the mandatory auction stage. Speak to a mortgage broker about refinancing options, and to a real estate lawyer if the property has already appeared on a published arrears list.
An owner who approaches the municipality early has more room to negotiate a payment arrangement than one who waits for the arrears list to be published.
Once a parcel is on the list, the municipality is working toward a fixed auction date, not an open-ended timeline.
The citable fact: An Alberta owner behind on property taxes has the most negotiating room before the annual arrears list is published under section 412(1), after which the municipality is working toward a fixed statutory auction date.

Do property tax arrears outrank a mortgage in Alberta?
Generally yes. Alberta’s tax recovery process under the Municipal Government Act runs on fixed statutory dates, regardless of what mortgage is registered on the property.
When does a parcel land on the tax arrears list?
Under section 412(1) of the Municipal Government Act, a municipality must list, by March 31 each year, every parcel with tax arrears outstanding for more than one year.
Does the municipality have to hold an auction once a parcel is listed?
Yes. Section 418(1) and (2) require the municipality to offer the parcel at public auction, held in the period ending March 31 of the following year.
Can an owner avoid the auction?
Section 418(4) lets the municipality agree with the owner to pay the arrears over a period not exceeding three years, during which the parcel need not be offered for sale.
How is the auction advertised?
Section 421(1) requires notice in The Alberta Gazette 40 to 90 days before the sale, and in a local newspaper 10 to 20 days before.
How is the reserve bid set?
Section 419 requires council to set the reserve bid as close as reasonably possible to market value, so the parcel does not sell for less than that.
Does a tax recovery sale wipe out a condo corporation’s caveat?
No. Section 39(11) of the Condominium Property Act says the caveat remains on title until paid even after a Municipal Government Act tax recovery proceeding, if an amount is still owing.
How is this different from Ontario’s tax sale process?
Alberta puts the municipality under an affirmative duty to auction a listed parcel within a fixed window. Ontario gives the owner a one-year cancellation window after a permissive certificate registration before a sale is even contemplated.
Will a land title search show tax arrears?
Not on its own. Alberta property tax arrears sit on the municipal tax roll and only become visible through the statutory arrears-list and auction process.
What should I do if my property is already on an arrears list?
Contact the municipal tax department about a payment arrangement under section 418(4), and speak to a real estate lawyer and a mortgage broker about the options available before the auction stage.
