Effective Monday, November 8, 2010, at 12 p.m.:
•Passengers are not permitted to transport printer toner cartridges in checked bags on any flights departing from Canadian 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.
•Passengers on outbound flights from Canada to the United States are not permitted to travel with cartridges in carry-on bags.
•Air carriers are not permitted to transport large printer cartridges in cargo carried on passenger flights departing from airports in Canada.
•All cargo and mail from or transiting through Yemen or Somalia are also banned from entering Canada.
These measures are being put in place as a result of two packages found in the United Kingdom and United Arab Emirates on October 29, 2010. They reflect discussions with domestic and international partners and respond to new requirements announced by the United States today.
bolding mine.
