What Is Customs Clearance in Canada?
Customs clearance in Canada is the formal process of declaring imported goods to the Canada Border Services Agency (CBSA), classifying them under the correct HS tariff code, calculating and paying applicable duties and taxes, and obtaining authorization for the goods to be released into Canadian commerce. All commercial shipments entering Canada must go through customs clearance.
The process is governed by the Customs Act and administered by CBSA. Importers can file customs entries themselves — a process called self-clearing — or authorize a licensed customs broker to act as their agent. Most commercial importers use a licensed customs broker to ensure accuracy and compliance.
Customs clearance happens at the port of entry — the Canadian airport, seaport, land border crossing, or rail crossing where the goods first arrive. CBSA officers review the customs entry and either release the goods, request additional information, or select the shipment for examination.
The Step-by-Step Customs Clearance Process
The process begins before the goods arrive. For ocean shipments, pre-arrival filing allows the customs entry to be submitted to CBSA before the vessel docks — often enabling release authorization before the ship arrives. This is strongly recommended for time-sensitive cargo.
Once the goods arrive and the customs entry is filed, CBSA reviews the entry electronically. The majority of low-risk entries are released quickly — often within hours — without physical examination. CBSA's automated risk targeting system identifies entries that require closer review.
After CBSA releases the shipment, the carrier or terminal operator releases the goods to the importer or their agent. The importer receives release documentation (the B3 entry or equivalent) and duty payment confirmation. For importers using Release Prior to Payment (RPP) under CARM, duties are paid through the monthly CBSA Statement of Account rather than at the time of release.
Documents Required for Customs Clearance in Canada
The standard document set for import customs clearance includes: the commercial invoice (showing seller, buyer, description of goods, quantity, unit price, and total value), the packing list (detailed breakdown of packages, weights, and dimensions), and the bill of lading or airway bill (the transport document issued by the carrier).
Depending on the commodity, additional documents may be required. Food products often require CFIA import permits or certificates. Certain chemicals, medical devices, and consumer products require Health Canada authorization. Controlled goods require Transport Canada permits. Ezcustoms reviews your specific commodity and confirms the complete document checklist before your shipment arrives.
All documents should state values in the currency of the transaction. CBSA converts foreign currency values to Canadian dollars using the Bank of Canada exchange rate for the week of import.
How Long Does Customs Clearance Take in Canada?
For routine commercial shipments with complete, accurate documentation, customs clearance in Canada typically takes a few hours to one business day. Pre-arrival filing — submitting the customs entry before the vessel or aircraft arrives — can result in release authorization before the shipment even lands.
CBSA examinations add significant time. A simple exam at a port examination facility may be completed in a few hours. A detailed exam involving full container devanning, laboratory testing, or document review can extend to several days. Ezcustoms coordinates examination logistics to minimize delay.
Missing documents, permit requirements, or CBSA queries about valuation or classification are the most common causes of clearance delays beyond the standard timeline. Ezcustoms proactively reviews documents and resolves any issues before the shipment arrives whenever possible.
What Causes Customs Clearance Delays in Canada?
The most common cause of clearance delays is incomplete or inaccurate documentation. A commercial invoice with missing information — no country of origin, incorrect valuation, or a vague product description — gives CBSA reason to hold the entry and request corrections.
Incorrect HS tariff classification is another frequent source of delay. If CBSA believes the goods are misclassified, they may reassess the entry and charge additional duties, or select the shipment for examination to verify the contents against the declaration.
CBSA examination is perhaps the most disruptive delay factor. Once a shipment is selected for examination, it must be physically inspected before release — and the importer bears the cost of container movement, devanning, and storage during the examination period.
