CARM Is Fully Enforced. Here's What That Actually Means for Importers.
CBSA's Assessment and Revenue Management system — CARM — completed its second release in January 2026. After years of delays, extensions, and partial rollouts, the system that fundamentally restructures Canada's customs accounting is now live and enforced.
Most Canadian importers know CARM exists. Far fewer understand what changed on their side of the ledger.
What CARM R2 actually changed
Before CARM, the relationship between importers and CBSA was mediated almost entirely by customs brokers. Brokers filed entries, managed payments, posted security, and handled reassessments on the importer's behalf. The importer's direct interaction with CBSA was minimal.
CARM R2 changed the principal relationship. The importer is now the account holder on their own customs account in the CBSA Client Portal. This means:
Financial responsibility is direct. Duties, taxes, and penalties assessed by CBSA are owed by the importer directly. The importer must post financial security — a bond, deposit, or surety — to cover potential reassessments. The amount is calculated based on import volume and compliance history.
Reassessments go to the importer. When CBSA questions a classification, valuation, or origin determination, the notice goes to the importer's account. The importer must respond. A broker can assist, but the obligation is the importer's.
Self-assessment is expected. CARM's architecture assumes the importer takes an active role in verifying their own compliance. The system provides tools for importers to review entries, request corrections, and manage their account — functions that were previously handled almost exclusively by brokers.
The broker relationship changes, not disappears. Licensed customs brokers remain essential for filing entries and navigating regulatory requirements. What changes is the assumption that the broker is the sole compliance owner. Under CARM, the importer and the broker share that responsibility, with the importer bearing the financial and legal exposure.
The 86% problem
As of early 2026, approximately 86% of Canadian importers had not established a fully CARM-compliant workflow. That means most importers have not:
- Registered and configured their CBSA Client Portal account
- Posted the required financial security
- Established internal processes for reviewing entry data before and after filing
- Set up delegation to brokers within the CARM framework
- Tested their ability to respond to reassessments through the portal
Some of these importers are operating on grace period goodwill. Others are simply unaware that their obligations changed. In either case, the enforcement clock is running.
CBSA has been clear that the transition period is over. Importers who have not established their CARM accounts risk having their entries held, their financial security requirements increased, or their compliance history flagged for review.
Why documentation matters more under CARM
Under the previous regime, documentation gaps were a broker problem. A missing invoice, an inconsistent origin declaration, a valuation discrepancy — these landed on the broker's desk, and the broker resolved them as part of the filing process. The importer often didn't know there was a problem until the broker asked for clarification.
Under CARM, documentation gaps are an importer problem. The importer is the account holder. The importer's compliance history is tracked. The importer's financial security is calculated based on that history.
This is where the upstream documentation problem meets CARM head-on. The same inconsistencies that cost importers $50,000–$250,000 annually in the US context carry equivalent exposure in Canada — but now with a direct line between the documentation gap and the importer's CBSA account.
An importer who sends inconsistent documentation to their broker is no longer just creating rework. They are generating a compliance record under their own name, on their own account, with financial consequences that CBSA can assess directly.
The financial security calculation
CARM requires importers to post financial security — an amount calculated by CBSA based on the importer's volume, commodity risk, and compliance history. This is new. Under the previous system, brokers typically posted security on behalf of their clients through continuous bonds.
The financial security requirement creates a direct financial incentive for clean documentation. Importers with strong compliance histories and low reassessment rates qualify for reduced security amounts. Importers with compliance issues — missed responses, frequent corrections, reassessments — face higher requirements.
Over time, this creates a feedback loop. Clean upstream documentation leads to fewer reassessments. Fewer reassessments lead to a better compliance history. A better compliance history leads to lower financial security requirements. The upstream investment pays for itself through reduced CBSA carrying costs.
The opposite loop is equally real. Poor documentation leads to reassessments. Reassessments worsen the compliance record. A worse record increases the security requirement. The importer is paying a premium for documentation problems they could have prevented upstream.
What CARM-ready looks like
A CARM-ready importer has three things in place:
Account infrastructure. CBSA Client Portal configured, financial security posted, broker delegations established, internal owner assigned to monitor the account.
Documentation discipline. Every entry filed on their behalf is supported by consistent, complete documentation assembled before filing — not reconstructed after a reassessment notice. This is pre-border trade readiness applied to the Canadian regulatory context.
Response capability. When CBSA issues a reassessment or a request for information, the importer can respond within the required timeframe with supporting evidence. This requires knowing what was filed, why it was filed that way, and where the supporting records are.
None of this replaces the customs broker. A licensed broker remains the filing expert, the regulatory navigator, and the authority on how entries should be structured. What CARM changes is the assumption that the broker alone is responsible for the evidence behind each entry.
The importers who recognized this shift early — who built upstream documentation practices and established their CARM accounts before enforcement began — are now operating with a structural advantage. Lower security requirements, faster clearances, fewer reassessments, and a compliance record that works in their favor rather than against them.
The importers who haven't are part of the 86%. The compliance clock is running.
