Compressed gas cylinder (non-medical)
Not Allowed
According to CATSA guidelines, this includes small gas cylinders containing carbon dioxide (CO₂), oxygen (O₂), or butane (C₄H₁₀), often used in curling irons, Thermacell units, or portable stoves. These are not allowed in carry-on baggage. You may be able to pack them in checked baggage, but only with your air carrier’s approval. Always check with your airline before you travel.
The final decision rests with the CATSA officer on whether an item is allowed through the checkpoint. Official CATSA Rules →
