That's the minimum age for a PPL. Additionally, there is the Recreational Pilot Permit (1 passenger max) with a minimum age (in Canada) of 16, and the Student Pilot Permit (solo only) with a minimum age here of 14.
That's the minimum age for a PPL.
That's the minimum age for a PPL with an Airplane rating. The Glider rating is 14/solo and 16/certificate. (I knew some kids who did this, but unfortunately I didn't go for it myself.) Also, while I think you can get a student pilot certificate in the U.S. at 14, you still have to be 16 to solo.
