most players of all Toronto sports teams are involved in many different foundations/charities of all types but for the most part th involve children who are disadvantaged in some way. It's a wonderful way to make the athlete's more approachable to the community. Much of it never makes it to the media and a lot of players do things on their own volition as well.
I'm sure the same is true of most teams in other cities.
