Transport Canada is amending the list of items that it will permit through security checkpoints for both domestic and international flights, adding restrictions around certain powders and granular materials but permitting smaller knives.

Starting November 27, 2017, Transport Canada will no longer permit certain powders and granular material with a volume of 350 ml (the size of a soda can) or more at all screening checkpoints in Canada. Prohibited material includes items such as bath salts, sea salt, baby powder, foot powder, cooking powder and sand, however, items such as baby formula, protein powder, tea and coffee will still be permitted in any quantity.

At the same time, in what it says is “consistent with international practice”, Transport Canada will now permit very small knife blades of 6 cm or less (about the size of a large paper clip). Although falling within the new size guidelines, razor blades and box cutters of any size will still be prohibited at all screening checkpoints.

While this applies to all domestic and international flights, Canada’s security screening agreement with the United States does not permit knife blades of any kind and therefore, all knife blades of any length will remain prohibited on flights to the United States through Canadian preclearance facilities.

“Adjustments to screening procedures are necessary from time to time to reflect changes in the security environment and to harmonize with international standards and partner countries.” said a release from Transport Canada.

"The safety and security of Canadians, the travelling public, and the transportation system are Transport Canada's top priorities.” said The Honourable Marc Garneau, federal minister of transport. “These changes to screening procedures will bring Canada in line with international standards and our partner countries, while continuing to keep passengers safe. The Government of Canada remains vigilant in continuously assessing security risks."

The Transport Canada website, listing prohibited items, has not yet been updated but will likely be updated by the end of the month.
