The CARM Client Portal changes the importer’s role from approving broker paperwork after the fact to managing an account with the Canada Border Services Agency. The importer remains responsible for the accuracy of the customs accounting, the duties and taxes owing, payment controls and any financial security required for participation in the Release Prior to Payment program, even when a licensed customs broker prepares and submits transactions.
For a company receiving freight through Pearson, a distribution facility in Mississauga or a warehouse serving Brampton and Toronto, that distinction affects accounting close, cash forecasting and document retention. The broker can handle customs work, but the importer needs a working process for reviewing entries and the account balance in CARM.
What CARM changes for the importer
CARM is the CBSA’s commercial accounting system and client-facing portal. It gives importers direct access to their account information, customs transactions, statements of account, payment arrangements and delegation relationships. A broker may continue to transact on an importer’s behalf, but the importer’s portal account is not simply a replacement inbox for broker documents.
The practical change is ownership of the accounting record. Importers generally need to:
- Register the business and maintain its legal-entity and contact information in the portal.
- Review the customs broker relationship and the authority granted to that broker.
- Understand which importer account and business number are attached to each import transaction.
- Monitor customs accounting declarations and statements of account.
- Arrange payment of duties and taxes by the applicable due date.
- Maintain any financial security required for the importer’s chosen release and payment arrangement.
This does not mean an importer has to perform every data-entry task internally. It means the importer needs controls around the data and the liability. A broker’s transmission of a declaration does not eliminate the importer’s obligation to provide complete commercial information or to identify an error after it is found.
The accounting sequence under CARM
1. Release and the import record
Release is the point at which goods are authorized to move from customs control, subject to the applicable program and transaction requirements. Release is not the same as final accounting. A shipment can move to a GTA warehouse while the importer still has to confirm the final accounting information, duties and taxes.
The information used at this stage normally includes the importer of record, seller, buyer, origin, tariff classification, customs value, currency, terms of sale and any applicable trade-program or tariff treatment. For air cargo arriving at Pearson or truck freight moving along the 401/407 corridor, the commercial documents supplied to the broker become the foundation for the accounting record.
Common operational mistake: treating a release notification as proof that the customs entry is complete and correct. A release message does not replace a review of the final accounting declaration or the resulting statement of account.
2. The Commercial Accounting Declaration
CARM uses the Commercial Accounting Declaration, commonly called the CAD, for the accounting of imported commercial goods. The CAD contains the information used to calculate duties and taxes and to establish the importer’s account liability. The broker may prepare and submit it, but the importer should have a way to compare the declaration with the purchase order, commercial invoice, freight records and receiving data.
Review should focus on fields that can change the amount payable or the future compliance position:
- Importer account and legal entity.
- Tariff classification and any applicable tariff treatment.
- Country of origin and supporting origin evidence.
- Value for duty, currency and valuation adjustments.
- Quantities, units of measure and product descriptions.
- Brokerage, assists, royalties, freight or other value elements where relevant to valuation.
- GST, excise or other tax treatment where applicable.
The appropriate review method depends on the importer’s volume and risk. A high-volume importer may use an exception report comparing broker data with its enterprise resource planning system. A smaller importer may use a shipment-level checklist. In either case, the control should identify who reviews the entry, what evidence is retained and how a discrepancy reaches the broker or internal trade-compliance owner.
3. The statement of account
CARM consolidates account activity into statements of account. The statement is the document the importer should use for the payable balance and payment planning, rather than relying only on individual broker invoices or shipment releases.
Finance and customs teams should reconcile the statement to the company’s import subledger. Useful matching fields include the accounting declaration number, transaction date, importer account, duty and tax amounts, adjustments, credits, payments and outstanding balance. The reconciliation should also identify items that were released but are absent from the expected accounting population, as well as duplicate or unexpected transactions.
A broker invoice may include a service charge or an amount advanced on the importer’s behalf. That document is not necessarily the same as the importer’s CBSA statement. Separating broker charges from government-account liability prevents an importer from paying the wrong party or overlooking a balance in the portal.
4. Payment and cash forecasting
Importers generally need to decide whether payment will be managed directly through CARM or through an agreed broker arrangement. The operating model should be documented before freight begins moving under the new process.
The importer’s finance team should know:
- Which entity owns the CARM account.
- Who can view statements and initiate or approve payment.
- Which payment method is being used.
- How the portal balance is reconciled to the general ledger.
- How payment evidence is retained.
- What happens when a payment, declaration or adjustment does not match the internal records.
This is particularly important for importers with regular inbound freight into Peel Region warehouses. A shipment may be physically received before the related customs liability has been fully reconciled, so receiving, accounts payable and customs teams need a common transaction reference.
Release Prior to Payment and financial security
Release Prior to Payment, or RPP, allows eligible importers to obtain release of qualifying goods before paying the duties and taxes at the time of release. Under CARM, importers participating in RPP generally need to meet the applicable financial-security requirements directly through the available security options.
The key accounting implication is that RPP is not free credit and is not a broker-controlled convenience. It creates a payment obligation that is collected through the importer’s account. The importer needs to understand its security arrangement, the amount or coverage required under the applicable rules, renewal or maintenance responsibilities and the effect of a lapse on release privileges.
Broker authorization and financial security are separate controls. Giving a broker authority to transact does not, by itself, transfer the importer’s responsibility for maintaining the security arrangement or paying the account balance. A broker can help explain the transaction flow and identify an operational problem, but the importer should own the decision about cash security, a surety arrangement and internal treasury approval.
What the broker does—and what remains with the importer
| Activity | Broker’s typical role | Importer’s control responsibility |
|---|---|---|
| Data preparation | Translate commercial documents into customs data and identify missing information. | Provide accurate documents, product details, origin information and valuation facts. |
| CAD submission | Prepare and transmit the accounting declaration under the agreed authority. | Review material fields and retain evidence supporting the declaration. |
| Statement review | Explain transaction-level discrepancies and assist with account research. | Reconcile the statement, approve payment and investigate unexplained balances. |
| Corrections | Submit an adjustment or other correction when the facts and authority support it. | Identify the error, provide evidence and approve the corrective treatment. |
| RPP operations | Coordinate release activity within the broker’s system and mandate. | Maintain the importer’s financial-security and payment arrangements. |
The exact division of work belongs in the broker agreement and operating procedure. A strong process states whether the broker or importer monitors statements, who approves corrections, who handles portal access and how urgent release issues are escalated.
Corrections, adjustments and audit readiness
Errors are easier to correct when an importer can connect the original declaration, the corrected commercial fact and the supporting evidence. Examples include a wrong tariff classification, a currency or value error, an incorrect origin claim, an omitted adjustment or a tax treatment that does not match the transaction.
When a discrepancy is found, the importer should generally:
- Record the transaction identifier and describe the error precisely.
- Collect the invoice, purchase order, product specification, origin record, freight document or other evidence relevant to the issue.
- Determine whether the problem affects duty, tax, tariff treatment, statistical information or more than one field.
- Send the broker a written correction request with the supporting record and the desired accounting result.
- Confirm that the adjustment was submitted and that the resulting account activity appears in the appropriate statement or transaction history.
- Update the internal import ledger and retain both the original and corrective records.
Do not treat a credit or debit on a broker invoice as proof that the customs account was corrected. The importer’s reconciliation should confirm the status in CARM and preserve the correspondence supporting the change.
Failure modes to prevent
Portal registration without process ownership
Registering the business is only the first step. If no one owns statement review, payment approval and access maintenance, the account can exist without being controlled. Assign responsibilities across customs, finance, purchasing and information technology, and establish a backup for each critical task.
Broker data accepted without product-level review
Descriptions copied from an old shipment can carry forward an incorrect classification, origin or valuation assumption. Importers should maintain product records and tell the broker when a product, supplier, material composition, packaging method or transaction structure changes.
Physical receiving separated from customs accounting
Warehouses may receive cartons while accounts payable sees only a supplier invoice. Match receiving records to customs transaction identifiers so that goods released into Toronto, Mississauga or Brampton facilities are included in the customs reconciliation.
Security and payment treated as broker issues
A broker may flag an account or release problem, but the importer needs its own calendar for payment, security maintenance and access reviews. Treasury should know the operational consequence of an unpaid balance or an unavailable security arrangement before a shipment is time-sensitive.
A practical monthly CARM control
A workable monthly close can be simple but should be repeatable. Export the relevant statement and transaction data from CARM, match it to the broker’s shipment report and the company’s receiving or purchase records, investigate unmatched items, approve corrections and document the final reconciliation. Review unusual changes in duty, tax, origin, classification or transaction volume rather than checking only the total balance.
For a GTA importer, this control connects the customs account to the physical flow through Pearson, local trucking routes and Peel Region distribution sites. It also gives the broker better instructions: instead of a general request to “check the entry,” the broker receives a transaction reference, a defined discrepancy and the evidence needed to assess the correction.
CARM does not remove the value of a customs broker. It makes the importer’s governance role more visible. The broker remains a technical and operational resource for classification, valuation, accounting submissions, corrections and release coordination. The importer, however, needs to own the account, understand the statement, control payment and maintain the records that demonstrate why the duties and taxes were calculated as reported.
For current portal procedures, account functions and program requirements, consult the CBSA CARM information and the applicable CARM client-portal guidance. A broker can help translate those requirements into a shipment and accounting workflow, but the correct process depends on the importer’s transactions, authorities and internal controls.
