Alberta’s Municipal Government (Restoring Tax Accountability) Amendment Act, 2021 changes how municipalities recover unpaid taxes on linear property—such as pipelines and utility infrastructure—and on machinery and equipment. It makes the owner jointly and severally liable with the assessed person, gives municipalities a broad priority lien, and extends the payment period for these taxes to 120 days after the tax notice is sent.
The legislation targets a narrow but consequential category of municipal revenue. The debt may arise from property that is difficult to seize or from an assessed person other than the asset’s owner, so the amendments give municipalities more parties and more property against which to enforce collection.
The lien also applies to qualifying debts that became due before the provision comes into force.
At a Glance
What It Does
The bill adds linear property to the Municipal Government Act’s improvement-related framework and makes its owner jointly and severally liable for unpaid taxes, alongside the assessed person. It creates a special lien over the debtor’s assessable property in the municipality, gives tax on linear property and machinery and equipment priority over most claims, and sets a 120-day payment period for those taxes.
Who It Affects
Municipalities collecting taxes on linear property, machinery and equipment, and specified property under section 304(1)(f) receive expanded recovery tools. Owners, assessed persons, secured creditors, lenders, insolvency professionals, and operators of pipelines, utilities, telecommunications systems, and other linear infrastructure must account for the expanded liability and lien exposure.
Why It Matters
The bill changes the risk profile of municipal tax arrears by reaching beyond the assessed person and beyond the specific taxed asset. Its retroactive application to existing debts may affect priority analysis, transactions, financing arrangements, and insolvency disputes involving assessable property located in an Alberta municipality.

What This Bill Actually Does
The bill focuses on two property categories: linear property and machinery and equipment. Linear property generally covers infrastructure assessed for municipal taxation, while machinery and equipment are already included in the Act’s definition of an improvement.
The amendment expressly adds linear property to that definition and updates related cross-references, including the clean energy improvement provisions.
For unpaid taxes, the bill creates joint and several liability. Once a tax on linear property or machinery and equipment remains unpaid after the due date shown on the tax notice, the owner becomes liable together with the person assessed for the property.
A municipality can therefore pursue the full tax debt from either liable party, rather than being limited to the assessed person alone. The text does not divide liability proportionally between them; a party that pays may need to resolve any contribution issue separately.The bill also creates a special statutory lien.
If the tax debt is not satisfied when due, the lien attaches to all of the debtor’s assessable property in the municipality, including assessable improvements, rather than only to the property that generated the tax. The lien ranks ahead of every claim except the Crown’s and continues until the debt is fully paid.
The provision applies whether the tax debt became due before or after the new section comes into force.The legislation pairs those stronger remedies with a longer payment window. For tax on linear property, machinery and equipment, or property covered by section 304(1)(f), the period for payment becomes 120 days after the municipality sends the tax notice.
Other property retains differentiated periods based on whether the person liable to pay is a resident or non-resident. The bill also updates tax-receipt language so that a municipality must provide a receipt when requested by the person who paid the tax, not only by the assessed person.The changes operate through amendments to the Municipal Government Act and take effect on proclamation.
That means the operative date is determined separately from the bill’s text, while the retroactive lien rule is expressly written to capture qualifying debts that arose before that date.
The Five Things You Need to Know
The owner of linear property or machinery and equipment becomes jointly and severally liable with the assessed person when the applicable tax remains unpaid after the tax notice’s due date.
The new lien covers all of the debtor’s assessable property in the municipality, including assessable improvements, not just the asset that generated the tax.
The lien has priority over every claim except the Crown’s and ends only when the tax debt is fully satisfied.
The special lien applies to qualifying tax debts that became due before or after the new provision comes into force.
The payment period for tax on linear property, machinery and equipment, and section 304(1)(f) property is 120 days after the municipality sends the tax notice.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Amends the Municipal Government Act
This provision identifies the Municipal Government Act as the statute being amended. The substantive changes that follow therefore operate within the Act’s existing assessment, tax collection, lien, and clean-energy-improvement framework.
Adds linear property to the improvement definition
The amendment adds linear property to the list of improvements in section 284(1)(j). That change ensures linear property is captured by provisions that rely on the statutory meaning of improvement and supports the bill’s related cross-reference changes.
Makes owners jointly liable for specified tax debts
Section 331 is amended so that the owner of linear property or machinery and equipment becomes jointly and severally liable with the assessed person when the tax remains unpaid after the due date. Municipalities gain a direct claim against the owner, even where the owner and assessed person are different parties.
The change strengthens collection but also creates diligence issues for owners, purchasers, lenders, and operators. Parties cannot assess exposure solely by checking who appears as the assessed person; they must also consider ownership and the payment status of the related municipal tax.
Allows the actual payer to request a receipt
Section 342 replaces “assessed person” with “person who paid the tax.” The municipality must therefore provide a receipt to the person who actually made the payment when that person requests one.
This is a targeted administrative correction. It accommodates situations in which an owner, lender, purchaser, agent, or other party pays the tax even though another person remains the assessed person.
Creates a priority lien over assessable property
New section 348.1 gives municipalities a special lien for unpaid taxes on linear property and machinery and equipment. The lien attaches to all of the debtor’s assessable property located within the municipality, including assessable improvements, and takes priority over every claim except the Crown’s.
The lien arises when the debtor fails to pay when due and expires when the debt is fully satisfied. Because the provision reaches property beyond the original taxed asset, it can affect unrelated municipal assets held by the same debtor and must be considered in secured lending, asset transfers, and insolvency analysis.
Updates clean-energy improvement cross-references
The bill updates section 390.1(1) so its exclusion for certain improvements refers separately to linear property, machinery and equipment, and designated manufactured homes. This preserves the intended connection between the new statutory classification and the clean energy improvement regime.
Sets the payment period for specialized property
Section 437 establishes a 120-day payment period after the municipality sends the tax notice for tax imposed on linear property, machinery and equipment, and property described in section 304(1)(f). The longer period replaces the ordinary resident and non-resident deadlines for those categories.
The amendment separates these specialized property taxes from the shorter periods that continue to apply to other property. The due date remains important because the owner-liability and lien provisions turn on failure to pay by that date.
Provides for commencement by proclamation
The Act comes into force on proclamation. The bill therefore does not set an automatic calendar date for the amendments to become operative.
The special lien provision separately states that it applies to qualifying debts due before or after commencement. That wording is the key transition rule for pre-existing arrears.
This bill is one of many.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Municipalities with unpaid linear-property tax accounts gain two additional recovery routes: direct recourse against the owner and a lien against the debtor’s other assessable property in the municipality.
- Municipal taxpayers generally benefit from a stronger municipal revenue-collection framework because improved recovery can reduce pressure to fund local services through other tax bases or spending reductions.
- Persons who pay municipal tax on behalf of an assessed person, including owners, purchasers, lenders, and agents, receive a clear statutory right to obtain a payment receipt.
- Municipal finance and collections departments gain a defined priority position that can simplify the municipality’s claim in competing-creditor and insolvency situations.
Who Bears the Cost
- Owners of pipelines, utilities, telecommunications infrastructure, and other linear property face direct liability for arrears even when another party is the assessed person.
- Companies that own machinery and equipment or operate across multiple municipalities must monitor tax notices and payment status more closely because a default can encumber other assessable property in the same municipality.
- Secured lenders and other creditors may face reduced recovery prospects because the new municipal lien ranks ahead of their claims, except for Crown claims.
- Insolvency professionals and restructuring advisors must account for potentially retroactive municipal liens when valuing or distributing assessable property located in Alberta municipalities.
- Municipalities must administer the longer payment period, identify the correct liable parties, and manage lien enforcement and receipt requests under the amended rules.
Key Issues
The Core Tension
The bill gives municipalities a reliable way to collect taxes from hard-to-reach infrastructure and its owners, but it does so by placing a powerful claim over parties and property that may not have caused the default. The central trade-off is between protecting local tax revenue and preserving the predictability of ownership, secured lending, and creditor priority—especially when the bill reaches debts that predate the new lien.
The bill trades a longer payment window for substantially stronger consequences after default. A 120-day period gives owners more time to arrange payment or challenge an assessment, but the resulting lien can reach every assessable asset of the debtor in the municipality.
The practical boundary between reasonable collection protection and overbroad encumbrance will depend on how municipalities identify debtors, property, and competing claims.
The retroactive application is the sharpest legal and commercial complication. A creditor, purchaser, or insolvency estate may have assessed its position before the new lien existed, yet the bill directs that the lien applies to debts that became due earlier.
The text gives the lien priority over every claim except the Crown’s, but it does not spell out all registration, notice, enforcement, or conflict rules that may determine how that priority operates in practice.
Joint and several liability also shifts risk within ownership and assessment arrangements. The owner may be pursued for the full amount even where the assessed person controlled the tax account or was contractually responsible for payment.
That may encourage stronger contractual protections and transaction diligence, but it can also generate disputes over ownership, reimbursement, and the allocation of tax risk.
