If you're importing into Canada and haven't yet dealt with the CBSA CARM portal, you're about to. The Assessment and Revenue Management initiative isn't new—CBSA started talking about it years ago—but the mandatory cutover date is firm: May 2025. After that, the legacy systems that handled your commercial accounting, duty deferrals, and security arrangements will be turned off. We've been guiding clients through CARM onboarding since the portal went live, and the transition has been uneven. Some importers breeze through. Others discover gaps in their corporate records or outdated Power of Attorney forms that stall enrollment for weeks. This article walks through what CARM is, what changed, and what you need to do if you haven't enrolled yet.
What the CBSA CARM Portal Actually Replaces
CARM consolidates three legacy systems: the Release Prior to Payment (RPP) program, the Revenue Management framework, and the paper-based financial security process. Under the old model, most commercial importers held RPP privileges tied to their Business Number (BN15), allowing goods to clear customs before duties were paid. Payment happened monthly through a manual reconciliation process, and financial security—typically a bond or cash deposit—was administered outside the electronic customs pipeline.
The CARM portal digitalizes all of this. Your financial security is now tied to your CARM Client Portal (CCP) account. Duty and tax payments happen through the portal on a commercial account-by-account basis. Release still happens before payment in most cases, but the legal and administrative framework is entirely new. Customs Act Section 32 now references CARM, and CBSA D-Memorandum D17-1-9 sets out the updated security requirements. If you were comfortable with the old RPP workflow, CARM is not a one-to-one replacement—it's a structural overhaul.
Enrollment and Delegated Authority: The Part That Trips People Up
To enroll in CARM, you need a valid Business Number and a My Business Account (MyBA) login with the Canada Revenue Agency. The authorized officer on your BN must either enroll personally or delegate authority to someone inside your organization—or to your customs broker.
This is where we see delays. If your registered officer left the company two years ago, if your corporate address on file doesn't match your current location, or if your BN was suspended for GST filing issues, you can't complete enrollment until those problems are fixed. CRA doesn't make exceptions. We've had clients spend four weeks untangling corporate registry mismatches before they could even access the portal.
Once you're in, you can delegate your broker. At CanFlow, we handle customs brokerage services for mid-market importers across the country, and we recommend delegating portal access early. Brokers need permission to view your statements of account, submit release requests, and in some cases manage your financial security. If you wait until the week before cutover, you'll be troubleshooting access issues while shipments sit at the border.
Financial Security: How Much and in What Form
CARM requires importers to post financial security to cover estimated duties and taxes. CBSA calculates your security requirement based on historical import volumes, typically covering your highest monthly duty obligation over the past year, plus a buffer. For mid-market importers, we commonly see security amounts between $25,000 and $500,000, though the range varies widely.
You can post security in three forms: a bond issued by a qualified surety, a certified cheque, or an irrevocable letter of credit. Bonds are the most common. Surety companies charge an annual premium—usually 1% to 3% of the bond value, depending on your creditworthiness and import history. If your company is new to importing or has uneven financials, expect the higher end of that range, or expect the surety to ask for collateral.
CBSA reviews security levels quarterly. If your import volumes climb, you may receive a notice to top up. If you don't, release privileges are suspended. This is stricter than the old RPP regime, where security reviews were less frequent and enforcement was spottier.
Statement of Account, Payment Cycles, and Penalties
Under CARM, CBSA issues a consolidated Statement of Account for each import transaction. You have until the last business day of the month following the accounting date to pay. Miss that deadline and interest starts at 6% annually, compounded daily, plus a penalty of 1.25% per month. These penalties are automatic—no grace period, no phone call.
For importers used to batching payments manually or relying on their broker to remind them, this is a culture shift. The portal sends email reminders, but if your accounts-payable team isn't checking the portal or if notifications are going to an inactive inbox, you'll miss deadlines. We recommend setting up at least two authorized users per company, with distinct logins and active email addresses.
If you also handle bonded warehouses, sufferance sites, or duty relief programs like duty drawback, those transactions now flow through CARM as well. Form B2 warehouse entries and Form B15 drawback claims are logged in the portal, and any errors or overpayments are reconciled there.
What Happens If You Don't Enroll by May 2025
After the cutover, importers without CARM enrollment won't be able to defer payment. Every shipment will require immediate payment at the time of release—either by your broker advancing funds or by you paying at a CBSA office. Your goods won't be held indefinitely, but the administrative friction will be significant, and brokers may decline to advance payments without a standing agreement and a deposit.
We've seen CBSA extend deadlines before, but the infrastructure for the legacy systems is being decommissioned. There's no technical fallback. If you're importing regularly, enrollment isn't optional.
How CanFlow Helps Mid-Market Importers Navigate CARM
We've onboarded more than a hundred CARM accounts over the past eighteen months. The smoothest transitions happen when the importer, the broker, and the accounting team coordinate early. We start by auditing your current BN and CRA standing, confirming your authorized officers, and mapping your typical duty cycle to estimate security needs. If you need help with compliance reviews, HS classification under the new portal workflow, or coordinating with sureties, we handle that as part of our service.
For importers who also need freight forwarding or multimodal logistics, we integrate CARM workflows with shipment tracking and documentation so you're not toggling between five different platforms.
