Canadian Customs for Freight: A Shipper's Guide to CBSA

If you’re shipping freight into Canada, CBSA (Canada Border Services Agency) is the gatekeeper you need to understand. Getting through customs smoothly means getting your documentation right, using the PARS pre-clearance system, and avoiding the common mistakes that hold freight at the border for days.

This guide focuses specifically on the Canadian import side. For the complete cross-border shipping picture including US exports and documentation requirements, see our Cross-Border LTL Shipping guide.

How goods enter Canada

Every commercial shipment entering Canada goes through a customs release process:

1. Pre-arrival documentation. Your customs broker electronically submits the entry data to CBSA before the freight reaches the border.

2. CBSA review. CBSA reviews the submission and makes a release decision: clear to cross, or held for inspection.

3. Border crossing. The carrier presents the freight at the border. If pre-cleared via PARS, the truck moves through quickly. If not pre-cleared or flagged for inspection, the truck waits.

4. Duty and tax assessment. CBSA assesses applicable duties and taxes based on the goods’ classification, value, and origin.

5. Release. Once cleared, the goods enter Canada and continue to their destination.

The PARS process in detail

PARS (Pre-Arrival Review System) is the key to smooth customs clearance. Without it, your freight waits at the border while paperwork is processed manually.

How PARS works

Step 1: Cargo Control Number. The carrier creates a Cargo Control Document with a unique number that identifies your shipment.

Step 2: PARS barcode label. A barcode sticker with the cargo control number is placed on your freight at the origin terminal (before it reaches the border).

Step 3: Broker filing. Your customs broker submits the entry data to CBSA electronically, linked to the cargo control number.

Step 4: CBSA review. CBSA reviews the submission. If everything checks out, they release the shipment electronically.

Step 5: Border scan. When the truck arrives at the border, the driver presents the PARS barcode. The border officer scans it, sees the electronic release, and waves the truck through.

The whole border crossing takes minutes when PARS is done properly. Without PARS, it can take hours or days.

PARS timeline

File your PARS entry at least 24-48 hours before the truck reaches the border. This gives CBSA time to review and process. Last-minute filings risk delays.

Required documents for Canadian imports

Canada Customs Invoice (CCI)

Required for commercial shipments valued over $2,500 CAD. The CCI provides detailed information CBSA needs to assess duties and taxes:

• Vendor (seller) name and address
• Purchaser name and address
• Consignee name and address
• Country of origin of the goods
• Detailed description of goods
• HS tariff classification
• Number of packages
• Total value in the currency of sale
• Terms of sale

Even when not legally required (under $2,500 CAD), including a CCI speeds up processing because it provides all the information CBSA needs in their preferred format.

Commercial invoice

Your standard commercial invoice must include the same key details: complete buyer/seller information, product descriptions, quantities, values, HS codes, and terms of sale.

The commercial invoice and CCI should match exactly. Discrepancies between documents are one of the top causes of CBSA holds.

Bill of Lading

Your BOL serves as the contract of carriage and is part of the customs documentation package. Cross-border BOLs must clearly show origin and destination countries.

USMCA Certificate of Origin

Required if you’re claiming preferential duty treatment under the United States-Mexico-Canada Agreement. This certifies that the goods meet the rules of origin for duty-free or reduced-duty treatment.

Duties and taxes

How duty rates work

Canadian duty rates are based on:

• HS code classification of the goods
• Country of origin (US, Mexico, and other USMCA countries may qualify for preferential rates)
• Trade agreements that apply

For US-origin goods under USMCA, many categories enter Canada duty-free. But “US origin” has a specific legal meaning under USMCA rules of origin. Goods manufactured in the US from Chinese components may not qualify.

For goods that don’t qualify for preferential treatment, duty rates vary by commodity, typically 0-25%.

GST and provincial taxes

All goods imported into Canada are subject to the federal Goods and Services Tax (GST) at 5%. Depending on the province of destination, you may also owe provincial sales tax (PST) or the combined Harmonized Sales Tax (HST):

Taxes are assessed on the total of: goods value + duty + freight cost + insurance.

De minimis thresholds

Canada’s de minimis thresholds are relatively low:

• Duties: Shipments valued under $150 CAD are exempt from duties
• Taxes: Shipments valued under $40 CAD are exempt from taxes

For most commercial freight shipments, these thresholds don’t apply because the value exceeds them.

Common causes of border delays

Incomplete documentation

The number one cause of customs delays. Missing commercial invoices, wrong HS codes, or mismatched information between documents. Always double-check that your commercial invoice, CCI, and BOL are complete and consistent.

No pre-clearance

Skipping PARS pre-clearance means manual processing at the border. This alone can add 1-3 business days to your transit time.

HS code disputes

If CBSA disagrees with your HS classification, they’ll hold the shipment while the correct code is determined. This can result in higher duties and delays. When in doubt, get a ruling from your customs broker before shipping.

Regulated goods

Certain goods require additional permits or inspections:

• Food products: Canadian Food Inspection Agency (CFIA) requirements
• Health products: Health Canada approval
• Textiles and clothing: Origin and labeling requirements
• Firearms and weapons: Strict import controls
• Plants and wood: Phytosanitary certificates

If your goods fall into a regulated category, work with your customs broker to ensure all permits are in place before the freight ships.

Incomplete country of origin declaration

CBSA requires country of origin for all imported goods. If your goods were manufactured in a third country (e.g., China) and shipped from the US, the country of origin is China, not the US. Getting this wrong can result in incorrect duty assessments and penalties.

Working with a customs broker

For any regular cross-border shipper, a customs broker is essential. They handle:

• HS code classification
• Duty and tax calculations
• Electronic filing with CBSA
• PARS processing
• Resolving customs holds
• Compliance with changing regulations

A good customs broker pays for themselves by avoiding delays and ensuring you don’t overpay on duties. Broker fees for standard LTL entries typically range from $40-$100 per shipment.
