Printer toner cartridges
Effective immediately, passengers are not permitted to transport printer toner cartridges in checked baggage on any flights departing from Canadian or U.S. airports if those cartridges weigh 454 grams (16 ounces) or more. These large, office-size toner cartridges are between 20 centimetres and 30 centimetres in length (8 to 12 inches respectively, or approximately the size of a loaf of bread). Smaller toner cartridges, such as those typically used in home printers, are still permitted.
In addition, passengers travelling on flights between Canada and the United States are not permitted to travel with cartridges in carry-on baggage.
Air carriers are not permitted to transport large printer cartridges in cargo carried on passenger flights departing from airports in Canada. For more information, visit the Transport Canada website.
