Is laser surgery good for children?

Hey,
My son is 14 years old, and he suffers from myopia. He used to say that he couldn't read anything from a long distance, and I realized that he feels more strain on reading. So, I took him to the clinic in Toronto, and they prescribed for glasses. He is a good ice hockey player. So he said that it would be difficult for him to carry glasses. So I searched for possible remedies and came to know about clinics providing laser eye surgery in Toronto. But one of my friends mentioned that laser surgery can only be done to people age above 18. Is that true? Are contact lenses safe for children? What are other possible remedies to remove spectacles other than laser surgery? Any help would be highly appreciated.
