Welcome to THUNDER LACROSSE. We used to be known as the MARKHAM THUNDER: Markham Minor Lacrosse Association (MMLA). Our club is growing with many new players of all ages from Richmond Hill, Thornhill, Stouffville, and Markham!

Registration for this year is online now. We look forward to seeing all the returning players and new players this season.
