The Canadian government is amending its list of items prohibited on commercial flights to include certain powders and granular material, to come in line with international standards.
According to Transport Canada, beginning Nov. 27, 2017, passengers on all domestic and international flights will not be allowed to carry on "certain powders and granular material with a volume of 350 ml (the size of a soda can) or more, including items such as bath salts, sea salt, baby powder, foot powder, cooking powder and sand."
Items such as baby formula, protein powder, tea and coffee will still be permitted in any quantity.
In the same announcement, Transport Canada reminded airline passengers that very small knife blades (6 cm or less, or about the size of a large paper clip) will be allowed on domestic or international flights. "To respect our security screening agreement with the United States, knife blades of any length will remain prohibited on flights to the United States through preclearance facilities. Razor blades and box cutters of any size will remain prohibited at all screening checkpoints."
