Taxes and assessment

Tax bill

Each year, tax bills are mailed out in early January. You can also view your tax bill online at municipal.acceo.com/immonet/Saint-Lambert.

If the total amount of your annual tax bill is $300 or more, you may pay it in four equal instalments. For 2025, the instalment due dates are:

February 10 April 14 June 16 August 18

Payment can be made directly at the recreation centre counter (600, Oak avenue) or by electronic transfer via your bank's website (allow 2 to 3 business days before the due date to avoid interest and a late penalty).

If you have any questions, you can contact the Info-Taxes line at 450 672-4444 or by email at finances@saint-lambert.ca.

If, for any reason, you do not receive your tax bill, you are still under obligation to pay your taxes within the deadlines stipulated by the City.

Special cases

Following the sale of a property, the new owner will not receive a tax bill or a statement in his or her name. The purchaser must ask the notary for a copy of the tax bills for the current year and enquire as to the state of the account at the Info-tax line at 450 672-4444.

If you receive the tax bill after the sale of your home, please send it to the new owner or to your real estate agent so that they can forward it.

If your mortgage creditor pays your taxes, make sure that their name appears in the appropriate box on your tax bill. If your mortgage creditor’s name does not appear in this box, you should ask them to add your name to the list they send to the City for future payments. It is possible that your mortgage creditor will ask you to send them a copy of your bill to meet the tax payment deadlines.

Payment of your taxes

Payment methods are as follows (Canadian money only):

  • In person at the Recreation centre tax office in cash, by debit card, by cheque or money order made out to 'Ville de Saint-Lambert'.
  • In person or via the Internet at most financial institutions (To find it more easily, enter only "lambert" in the search engine.). You must then enter the 20-digit electronic payment file number that appears on your tax account coupons. Do not enter the matricule or invoice number.
  • By mail to: Recreation centre, 600 Oak Avenue, Saint-Lambert, Quebec, J4P 2R6. Please note that last year we opted to go green and no longer include a return envelope when sending out tax bills.

To avoid interest charges, we strongly recommend that you allow at least three business days for payments made at financial institutions or by mail. Since January 1, 2023, overdue accounts carry annual interest charges of 10% and an annual penalty of 5%.

If you wish to cancel a cheque or postpone the date of cashing, you should call INFO-TAXES Saint-Lambert at 450-672-4444 at least 5 days before the date indicated on your cheque. Please note, however, that a fee of $10.00 per cheque will be added to your file for this transaction.

Please note that the Ville de Saint-Lambert will charge bank fees for NSF cheques. These fees are $40.00.

A copy of your tax bill is sufficient for income tax purposes or for your mortgage creditor. If you wish, you can come to the tax office in person to obtain a copy of your tax bill, at a cost of $5.00, or a payment receipt, at a cost of $5.00.

If you don’t pay your tax bill, your property will eventually be liable for tax proceedings due to non-payment of taxes. The next sale will take place in 2025. This sale will include properties for which taxes due in 2023 have not been paid in full.


Are you 65 or over? Has your tax bill increased? You may be eligible for assistance from the Quebec government to pay your municipal taxes.

Provided by Revenu Québec when you file your annual income tax return, this grant is offered to seniors to help offset an increase in the municipal taxes payable on their residence following a significant increase in its value.

For more information, to find out the eligibility criteria or to obtain the form, visit Revenu Québec’s website.

You can also call Revenu Québec at 418-266-1016.

Access your tax account

This section explains the different ways you can access your municipal tax account.

You can view your tax account online by registering for free on our online platform. This will provide you with a copy of your tax account, as well as secure access to a wide range of information about your property, such as your actual balance and bills.

Once you've registered, you will no longer receive your tax bill by mail. Instead, you'll receive an e-mail notification that your new account is available for viewing online. You'll also receive a reminder a few days before each due date.

To access your tax account online, you must first register on the platform. To do this, you'll need your last annual tax bill issued in January, in paper format, showing your tax bill number and the amount of your first payment.

This is a tax account consultation platform, not a tax account payment platform. To pay your tax bill, visit the “Paying your taxes” section above.

For more information, watch this video:

You can access the tax roll and assessment roll for any property in Saint-Lambert. This is a document on which the owner's statement of account and contact details do not appear.

Are you a recognized professional? Notary, real estate agent, mortgagee or other? For a fee, you can access additional information on a tax bill or assessment roll for a Saint-Lambert property.

You may already be registered on the portal for another city. If so, you can use the same account as for the other city. If you don't have a business account to use the portal, you can create one now.

As well as making your online application experience more pleasant, you'll find that fees are deducted as you use the wallet.

Property tax rate

For 2025, the property tax rate has been set per $100 valuation, according to the following:

Catégories 2025 rate ($) Saint-Lambert ($) Progressive cash payment program ($) Agglomeration and CMM ($)
Non residential 2.5300 1.0632 0.1796 1.2872
Industrial immovables 2.5445 1.0693 0.1806 1.2946
Residential buildings - 6 or more dwellings 0.9015 0.3788 0.0640 0.4587
Serviced vacant land 2.9080 1.2220 0.2064 1.4796
Residual 0.7270 0.3055 0.0516 0.3699

When the valuation roll is deposited, if the value of your home entered on the roll increases, your taxes will not increase by the same amount. The tax rate takes into account the services provided by the City as well as the valuation of all buildings, not just the increase in value of your home.

In addition to property taxes, other offsets may be payable, such as for the supply of water for a residential swimming pool. For more information, consult the By-law 2024-238 concerning the imposition and levying of the general property tax and compensations for fiscal year 2025 (in French).

Local or sector improvement tax

Local or sector improvement tax is used to pay back, over periods varying from 15 to 30 years, loans taken out by the municipality to finance part or all of the cost of new municipal infrastructures such as sewers, water mains, paving, and street lighting.

The work is first authorized by means of a by-law ordering the funds that need to be borrowed through the issue of renewable bonds for 5-, 7- or 10-year periods during the term of the by-law. The cost of the work is distributed on a pro-rata basis, usually according to property frontage or surface areas affected by the work.

The amount of sector tax shown on your municipal tax bill is the sum of all the by-laws affecting your property. It is important to point out that sector taxes vary across the municipality because not all new infrastructures were built at the same time.

Property assessment roll

The property assessment function is under the jurisdiction of the Longueuil agglomeration. For the territory of Saint-Lambert and the other related municipalities, it is overseen by the agglomeration’s Assessment Department.

Visit the Property Assessment page of the Ville de Longueuil website to consult the assessment roll, register a change of address, or apply for a review of your property assessment. You can also call the agglomeration’s Info-évaluation service at 450-463-7177.
