I think its because paintball and airsoft were always around in the United States and has gained acceptance regarding law enforceable and the like where as Canada hasn't been so forward. Give it some time, I'm pretty sure the age will drop due to more and more people becoming interested in the sport.
(BTW T7 and Pus found out why the orange tip is required, its federal law to have it on and if you don't you'll be facing weapons charges.)
