If you're importing commercial goods into Canada, you've probably been told you need a canadian customs broker. But what does that actually mean beyond filing paperwork? We've cleared more than 40,000 shipments in the last five years, and we still see confusion about what brokers do, what they cost, and when you're legally required to use one versus when it just makes sense.
What a Canadian Customs Broker Does on Every Entry
Every time commercial goods cross into Canada, someone has to file a B3 Customs Coding Form with the Canada Border Services Agency. That filing includes the tariff classification (HS code), declared value, country of origin, applicable duty and GST calculations, and any trade agreement claims like CUSMA. Your broker submits this electronically through the CBSA Assessment and Revenue Management system (CARM), posts security if required, and arranges release of your shipment.
We also submit the cargo control document (CCI or ACI, depending on mode) before the goods arrive. Miss that deadline and your shipment sits at the border accruing storage fees while CBSA issues an administrative monetary penalty that starts at $250 for a first offence under the Customs Act.
After release, we prepare the final accounting (Form B2) within five business days. That's where duty and tax are finalized. If your importer account isn't enrolled in the Commercial Accounting Declaration program, you pay immediately at release. Most of our mid-market clients use CAD to defer payments to a monthly cycle, which helps with cash flow when you're bringing in $100,000+ worth of product every month.
When You're Legally Required to Use a Licensed Broker
You're not always required to hire a customs broker. Section 32 of the Customs Act lets any person account for their own goods. Walk up to a CBSA office with your commercial invoice, packing list, and a completed paper B3, and you can clear a small shipment yourself.
But here's the practical reality: CBSA moved almost all commercial processing to CARM Client Portal in 2024. To use the portal as an importer of record, you need a business number, a CARM enrollment, financial security posted with CBSA (often $5,000 to $25,000 depending on your monthly duty liability), and someone on staff who knows how to classify products to the eight-digit HS level and navigate origin determinations.
We see companies try the self-clearance route when they're doing one or two shipments a year. It works until it doesn't. A misclassified tariff code can mean you underpaid duty by thousands of dollars, and CBSA can audit and reassess up to four years back. A missed anti-dumping declaration can trigger penalties equal to the value of the goods. For most businesses importing regularly, the risk isn't worth the $75 to $150 per-entry brokerage fee.
How Brokerage Fees Actually Work
Most brokers charge a per-entry fee that varies by shipment complexity and volume. For a standard LTL or courier shipment with straightforward HS classification, expect $100 to $175. If you're a high-volume client clearing 50+ entries a month, that often drops to $60 to $90 per entry under a retainer agreement.
Additional services cost extra. If we need to apply for a CBSA ruling on tariff classification, that's usually $400 to $800 depending on research required. Duty drawback claims to recover duties on re-exported or destroyed goods run $500 to $1,200 depending on how many entries we're tracing. Compliance reviews and preparing for a CBSA verification typically start around $1,500.
You'll also see brokers charge for disbursements: duty, GST, and any advances for things like CFIA inspections or fumigation. We collect those on CBSA's behalf and remit them. Some brokers mark up disbursements by 1% to 2% as a financing fee. We don't. You pay exactly what CBSA and other agencies assess.
Tariff Classification and Why It Matters More Than You Think
The single biggest compliance risk we see is misclassification. Every product imported into Canada must be assigned a 10-digit HS code from the Canadian Customs Tariff. The first six digits are internationally harmonized. The last four are Canada-specific and determine your duty rate, whether you qualify for a trade agreement, and which regulations apply.
Misclassify a garment as woven when it's knit, and you might pay 18% duty instead of 16%. Misclassify an electrical component and you might trigger certification requirements you weren't prepared for, delaying your shipment for weeks.
We use the HS classification tool on every new product line and confirm it against CBSA's Customs Tariff and any applicable D-Memoranda. If there's any ambiguity, we apply for an advance ruling (Form B2G) so you have written confirmation from CBSA before the first shipment moves. That ruling is binding, and it protects you in an audit.
CARM, Financial Security, and What Changed in 2024
CBSA's full CARM rollout in 2024 changed how importers interact with the agency. If you're the importer of record, you now manage your own CARM account, post your own financial security, and receive assessment and adjustment notices directly in the portal.
That means your broker is no longer the intermediary for everything. We still file entries and manage compliance on your behalf, but you're responsible for monitoring your portal, paying invoices, and keeping security topped up. If your security drops below the threshold, CBSA stops releasing your shipments until you post more.
We help clients calculate security requirements, set up their CARM enrollment, and train their A/P teams on the monthly statement cycle. For most mid-market importers bringing in $50,000 to $500,000 in goods per month, expect to post $5,000 to $50,000 in security, either as a cash deposit or a bonding company surety.
Choosing a Broker: What Actually Matters
Not all brokers are the same. The big multinational brokerages tied to courier companies excel at high-volume, low-touch clearances. If you're shipping 500 identical parcels a month, that model works. If you're a mid-market importer bringing in industrial components, food products, or anything requiring duty relief programs or regulatory coordination, you need a broker who picks up the phone.
We're licensed customs brokers, which means we've passed the CBSA professional examination and we're accountable under the Customs Brokers Licensing Regulations. We carry errors and omissions insurance. And we work with the same clients for years because we learn your products, your supply chain, and your risk tolerance.
When you're evaluating brokers, ask how they handle classification disputes, how quickly they respond to CBSA queries, and whether they have in-house freight forwarding if you need help coordinating the full move. Ask for a sample entry summary so you can see how they document their work. And ask what happens if CBSA selects a shipment for examination—do you get a call, or do you find out when the truck is three days late?
Work With a Broker Who Knows Your Business
If you're importing into Canada on a regular basis, you need a broker who understands compliance, communicates clearly, and doesn't treat you like a transaction. We work with mid-market importers who value accuracy and transparency, and we're happy to walk you through what a partnership looks like.
Get in touch and we'll review your supply chain, explain exactly what we'd do on each entry, and give you a clear quote with no surprises.
