For Canadian importers, few things are more frustrating than a shipment getting stuck at the border. Whether it’s a last-minute compliance issue or an unexpected customs inspection, border delays can derail delivery timelines, strain supplier relationships, and cost businesses real money, especially for small and mid-sized importers who rely on consistent turnover.

Fortunately, with proper planning, many of these delays can be entirely preventable. In this blog, we’ll explore the most common reasons shipments get held up at the Canadian border and share practical steps to reduce disruptions and keep your supply chain moving smoothly.

Why Shipments Get Delayed at the Canadian Border

Here are the most common reasons your goods might be flagged or delayed:

  • Incomplete or inaccurate documentation (e.g., missing commercial invoice details or wrong HS codes)
  • Improper tariff classification, leading to extended reviews or reclassification
  • Non-compliance with Canadian regulations (especially for regulated goods like food, electronics, or pharmaceuticals)
  • Random inspections by CBSA (Canada Border Services Agency)
  • Unpaid duties, surtaxes, or Goods and Services Tax (GST) owed at the time of clearance
  • Seasonal congestion at ports or border crossings

Delays don’t just disrupt schedules—they drive up warehousing costs, increase the risk of stockouts, and weaken customer trust. Even worse, repeated issues can raise red flags for CBSA, increasing the likelihood of future scrutiny.

Ensure Documentation is Complete and Accurate

The first and most crucial step to avoiding delays is to ensure your paperwork is accurate. Missing fields, unclear item descriptions, or mismatched data between forms are major red flags for customs officers.

What to check every time:

  • Commercial Invoice: Ensure that product descriptions match your Harmonized System (HS) codes
  • Packing list: Confirm quantities, units, and weights
  • Certificate of origin: This is especially important for goods under free trade agreements
  • Import permits are required for certain goods, including alcohol, pharmaceuticals, and dairy products

Discover how misclassified imports can impact duties and compliance, and learn what steps to take to address the issue.

Use the Correct HS Codes and Know the Duties

Incorrect tariff classification leads to more than just delays; it can result in overpayment, penalties, or missed opportunities for preferential treatment.

Be especially cautious when importing goods that are subject to high tariffs, have special regulatory conditions, or trigger additional inspections. For example, certain electronics and food products are assigned specific codes that trigger inspections or require further documentation.

Be Aware of Tariff and Surtax Changes

Canada’s tariff landscape has changed in response to international trade tensions. Surtaxes on U.S. goods and retaliatory measures mean that goods you’ve imported for years could now carry added costs or delays.

If your goods are affected by new trade policies or are listed on CBSA’s retaliatory surtax list. These goods may be subject to additional inspection, documentation requirements, or surtaxes upon arrival.

Stay Ahead of Seasonal and Port Delays

The holidays, Chinese New Year, and back-to-school season often see significant surges in cargo volume. These seasonal spikes result in longer clearance times and congestion at ports of entry, such as Vancouver and Montreal.

What you can do:

  • Plan by building lead time into your procurement schedule
  • Choose less congested ports when possible.
  • Work with a broker who knows the seasonal flow of goods and can pre-clear shipments when appropriate.

Leverage a Customs Broker Who Works Proactively

Even the best internal logistics teams may lack the up-to-date knowledge or experience necessary to navigate border rules, particularly when handling multiple product categories or countries of origin.

A licensed Canadian customs broker does more than just process entries. They can:

  • Pre-audit documentation to reduce the risk of rejection
  • Monitor for policy changes that may affect your products
  • Handle permits, licenses, and temporary importation if needed
  • Clear shipments electronically to minimize hold times

Understand Product-Specific Requirements

Many categories, such as medical devices, dairy, food supplements, and electronics, require compliance with federal agencies like Health Canada, the Canadian Food Inspection Agency (CFIA), or Innovation, Science, and Economic Development Canada (ISED).

Missing documentation from these agencies is a common cause of border delays.
