All magazines, certainly all Canadian magazines, are very niche oriented, so whatever interests people in a particular age group is what they'll be going to. Interestingly, technology and computer magazines are very popular in print, and young people read a lot of those magazines. Canada does not specialize in celebrity magazines per se, but we certainly have a lot of interests, such as Canadian history and various niche products.
Young people do not seem to have focused in any particular area, but they do have their own interests, including the astronomy magazine I mentioned.
