Loading boxes into cargo hold

Weight, dimensions and how to package general cargo

Know how to package your shipment with the following weight, size and packaging guidelines:


For general cargo, maximum weight per piece is 136 kilograms or 300 pounds. Please contact us for shipments exceeding this weight. For seafood, the maximum weight per piece is 36 kilograms or 80 pounds. We are unable to ship seafood beyond this weight.


The maximum height of any single piece of cargo must not exceed 70 centimetres or 31 inches.

Total size

A package may not exceed a combined total of 228 centimetres or 90 inches. A package’s total size can be determined by adding the length plus the width plus the height of the shipping container. Please contact us for packages exceeding these dimensions.

Volumetric weight

The cost for each shipment is based on actual or volumetric weight, whichever is greater of the two. Here is how to determine the weight of a shipment:

Dimensions in centimetres: Multiply length by width by height. Divide the total by 6000. The result represents the volumetric weight in kilograms.

Example: box weighing 42 kilos measuring 70cm x 70cm x 70cm = 343000. Results divided by 6000 = 57kg. Cost is based on 57kg.

Dimensions in inches: Multiply length by width by height. Divide the total by 366. The result represents the volumetric weight in kilograms.

Example: box weighing 26 kilos measuring 20cm x 10cm x 15cm = 3000. Results divided by 366 = 8kg. Cost is based on 8kg.

Packaging and marking requirements

Transport Canada regulations specify that every package must be secure before being loaded on board an aircraft. In order to make sure that your package is secure, warehouse personnel at your shipment’s origin must complete a verification of all pieces in your shipment. Please also ensure that:

  • every shipment contains a packing list of all the items included;
  • the shipment is prepared to ensure safe carriage assuming ordinary care and handling;
  • fragile shipments prone to damage under ordinary care and handling, high or low atmospheric pressure, or changes in temperature are packaged and labelled appropriately;
  • Styrofoam is not used as a form of outer packaging;
  • every piece of the shipment is legibly and durably marked with the name and address of the shipper and consignee;
  • the packaging of human remains meets all appropriate shipping requirements.
