This website is explaining how and where you can sign up for BC lacrosse.

It is important to know where to sign up if you intend to play or understand the game. It is not a big deal if you don’t intend to play, but if you would like to play then you should know where to sign up. The math part about this is the amount it costs to sign up, the time span you have to sign up, and the time span of how long you will play for. Time spam being the amount of time you will be able to lay for as well as the months throughout the season.
