I happen to be travelling next month, and I did find this useful link as to what can and cannot be brought on the plane, for carry on luggage: http://www.catsa-acsta.gc.ca/english/travel_voyage/list.shtml#explosivesThe reason why I was looking was to make sure I could bring my knitting.... But, sadly, it looks like I have to leave my morning stars and nunchucks at home... Of course, always check with your airline just to make sure before leaving.
